Bizarre rogue planet discovered wandering in our galaxy

A bizarre rogue planet without a star is roaming the Milky Way just 20 light-years from the Sun. And according to a recently published study in The Astrophysical Journal, this strange, nomadic world has an incredibly powerful magnetic field that is some 4 million times stronger than Earth’s. Furthermore, it generates spectacular auroras that would put our own northern lights to shame.

The new observations, made with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA), not only are the first radio observations of a planetary-mass object beyond our solar system, but also mark the first time researchers have measured the magnetic field of such a body.

Sizing up SIMP

The peculiar and untethered object, succinctly named SIMP J01365663+0933473 (we’ll call it SIMP for simplicity’s sake), was first discovered back in 2016. At the time, researchers thought SIMP was a brown dwarf: an object that’s too big to be a planet, but too small to be a star. However, last year, another study showed that SIMP is just small enough, at 12.7 times the mass and 1.2 times the radius of Jupiter, to be considered a planet — albeit a mammoth one.

“This object is right at the boundary between a planet and a brown dwarf, or ‘failed star,’ and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets,” said Arizona State University’s Melodie Kao, who led the new study on SIMP, in a press release.

For a planet, SIMP is also pretty hot: The world has a surface temperature of over 1,500 degrees Fahrenheit (825 Celsius). For comparison, the hottest planet in our solar system is Venus, which sports an average temperature of around 875 F (470 C), while the Sun, a relatively small and cool star, has a surface temperature of about 10,000 F (5,500 C). However, it’s important to note that Venus gets most of its heat from the Sun. And since solitary SIMP is not orbiting a star, its heat must be leftover from its initial formation some 200 million years ago. So, over time, the planetary goliath will continue to radiate away its warmth.

Unparalleled magnetism

According to the most recent study, SIMP is not only gigantic by planetary standards, but it also possesses a magnetic field that is millions of times stronger than that of our home planet. And although this magnetic field helps SIMP produce stunning light shows, the auroras are not generated in the same way as they are here on Earth.

The paper: The Strongest Magnetic Fields on the Coolest Brown Dwarfs

Abstract

We have used NSF’s Karl G. Jansky Very Large Array to observe a sample of five known radio-emitting late-L and T dwarfs ranging in age from ~0.2 to 3.4 Gyr. We observed each target for seven hours, extending to higher frequencies than previously attempted and establishing proportionally higher limits on maximum surface magnetic field strengths. Detections of circularly polarized pulses at 8–12 GHz yield measurements of 3.2–4.1 kG localized magnetic fields on four of our targets, including the archetypal cloud variable and likely planetary-mass object T2.5 dwarf SIMP J01365663+0933473. We additionally detect a pulse at 15–16.5 GHz for the T6.5 dwarf 2MASS 10475385+2124234, corresponding to a localized 5.6 kG field strength. For the same object, we tentatively detect a 16.5–18 GHz pulse, corresponding to a localized 6.2 kG field strength. We measure rotation periods between ~1.47–2.28 hr for 2MASS J10430758+2225236, 2MASS J12373919+6526148, and SDSS J04234858–0414035, supporting (i) an emerging consensus that rapid rotation may be important for producing strong dipole fields in convective dynamos, and/or (ii) rapid rotation is a key ingredient for driving the current systems powering auroral radio emission. We observe evidence of variable structure in the frequency-dependent time series of our targets on timescales shorter than a rotation period, suggesting a higher degree of variability in the current systems near the surfaces of brown dwarfs. Finally, we find that age, mass, and temperature together cannot account for the strong magnetic fields produced by our targets.

When Dancing with the Stars , no wanders are barred – “It’s Electric”! -Boogie ,Woogie ,Woogie https://www.youtube.com/watch?v=5jBkoEM0SSE

Tom in Florida

Thanks, hadn’t heard that snappy little tune in quite a while.

Greg

interesting that being strong, free and independent and not enslaving others is classified as rogue.

Rogue as in Bundy Bros. maybe.

RIP ‘LaVoy’ Finicum, a law abiding , patriotic rogue planet.

RAH

That planet could “enslave” plenty if it comes close to it. And exactly how do you know it’ doesn’t have a moon or many moons? BTW Rouge also means it could come crashing into our or another solar system. I personally don’t want such a mass to come crashing into ours and “free” our planet from it’s “enslavement” to our sun. Do you?

Theo

There are thought to be billions of rogue planets in our galaxy. They’re either planets which formed around a star, but then were ejected from the star system, or brown dwarfs, ie large planets without quite enough mass to form the smallest stars, ie red dwarfs.

Michael S. Kelly, LS, BSA, Ret.

What does a planet have to do to get ejected from its solar system? Those “rogue planets” have got to be some of the most badass objects in the universe!

Greg

Usually failure to follow US foreign policy 😉

First it’s sanctions, then regime change and if that does not bring them into line : reclassification as a rogue planet and : ejection.

Alan D McIntire

Watching the TV show, “How The Universe Works” I discovered that OUR solar system is rather freakish. Most other systems with planets have inner planets with maybe 3 to 5 times the mass of our Earth, somewhere between the masses of Earth and Neptune.

One way to account for this is that there WERE several super Earth’s in our system, but Jupiter moved in towards the Sun and disrupted their orbits. Some super Earths were flung into the Sun, some escaped into interstellar space, and some were destroyed in collisions, leaving a small amount of debris. The current inner planets, Mercury, Venus, Earth, and Mars, were formed by that left over debris to form second generation planets.

https://astronomynow.com/2015/03/25/wandering-jupiter-swept-away-super-earths-creating-our-unusual-solar-system/

Here’s a link to another story showing that diamonds found in meteorites must have formed under pressure in the interior of a prior planet at LEAST as massive as Mars

https://www.usatoday.com/story/tech/science/2018/04/18/space-diamonds-may-have-come-large-lost-planet-study-says/527345002/

Tom in Florida

Or you can think along the lines of OM:
“We think that the solar system came from a single star, and the sun formed on a collapsed supernova core. The inner planets are made mostly of matter produced in the inner part of that star, and the outer planets of material form the outer layers of that star.”

MarkW

First off, a star that’s big enough that it’s core would be out to the orbit of Mars, when it blew up, it would form a rather massive black hole, not a solar system.
Secondly, you don’t have to go that exotic. Once the star ignites, it will blow all the gas out of the inner solar system.

Crispin in Waterloo

It used to be taught that there is a general case formula for the mass and orbital radius for sets of planets around a star. The distance between orbital radii is certainly to do with orbital resonances, though that was never mentioned. There is a 2:5 beat frequency for Venus and Earth, and an 11:12 beat frequency for Jupiter and Saturn. While we are not allowed to talk about it on this channel, these resonances have visible and predictable effects on the Sun.

The current long slow El Nino with a general drought across the US of A was predicted 14 years ago based on such resonances alone. Another visible manifestation is the way sunspots move to create butterfly charts. That is caused by the position and movement of the centre of mass of the Earth-Moon-Venus group. The beat frequency is evident in that.

Rogue planets will be ‘offbeat’ when formed and their orbits will be disturbed enough that they wander away at some point. This huge black dwarf star that never lit up is an interesting lump. It would be even more interesting if it turns out there is a small nuclear fusion reactor humming away inside, too small to heat the surface up to ‘radiant’ status.

johann wundersamer

Sure we’re allowed to discuss planets’ influence on other planets when with the last ‘blue moon’ emergency Mars again built a huge flooding on Earth’s beaches and river inlets.

Gary Ashe

Well these things happen when you mess with black holes, gravity will pull ya further than a big bang will throw ya.

When two objects in orbit around a star are in unstable orbits it’s possible for one to transfer kinetic energy to the other, the one losing energy moves closer to the star and the one gaining energy accelerates and moves away from the star. If the kick is sufficient the accelerated object will abandon the system.

This is used to accelerate probes going out (they usually boost speeds using Jupiter). Probes heading inward have to reduce speed doing braking maneuvers (this is done for probes going to Venus, Mercury or close to the Sun).

LarryD

In addition, when a massive gas giant moves inward, it will scatter inner planets into eccentric orbits, and some of them may end up ejected entirely. Solar system formation studies indicate that the process is very chaotic. One of the things that makes our system unusual is that Jupiter hardly moved at all, just enough to thin out the asteroid belt

Keitho

They probably support Donald Trump and those lefty stars couldn’t deal with it.

Greg

I’d never heard of the concept before last week, now there are “billions” of them. So much for settled science.

Tom Abbott

There is also estimated to be hundreds of millions of stellar-mass black holes obiting the galaxy.

Tom Abbott

From the article: “And since solitary SIMP is not orbiting a star, its heat must be leftover from its initial formation some 200 million years ago.”

I wonder if they can trace SIMP back to its original star system.

Greg

They only have two years of observations. I doubt that they have detected the slightest movement in that time at that distance. Next year they may find it is in a binary system with a nearby brown dwarf they have not seen yet.

the more we find , the more we see the depth of our ignorance and the false assumptions we have made so far.

Now, tell me about al the settles science we have established about the climate system, and how the “debate” is over.

Mark

And here is your dark matter.

The MACHO survey supposedly set the number of dark massive objects low enough to discard the possibility. I’m hoping that numerical relativity (solving the Einstein equations using a computer to estimate the metric) will find that dark matter isn’t needed after all. Otherwise science will have to move on to a theory of quantum spacetime and gravity.

joelobryan

The second group to observe SIMP0136 used the Keck II Telescope on 2013 October 16 and 2016 February 2. Two exposures of 900 sec (2013 October) and 750 sec (2016 February) were obtained at air masses of 1.11 and 1.15, yielding signal-to-noise ratios of ∼20 and ∼13 per pixel after reduction. From these observations the position and kinematics of SIMP0136 were nailed down pretty well.

joelobryan

SIMP J01365663+0933473 (SIMP0136 for short) is a member of the relatively young 200 million old Carina-Near stellar moving group. SIMP0136 is “near-by” at a distance of about 20.2 Ly. The Carina-Near group core members have an average distance from Earth (28-33 parsec, or about 91-108 Ly) and appear in the night sky in the constellation Pisces. This T2.5 dwarf has very similar galactic velocity elements to Carina-Near, thus it is believed to be a trailing member of this moving group.

One star in the Carina-Near group (HD62850) is an interesting G2IV (sub-giant, slightly more massive than the sun) class star with a surface temperature estimated at 5789 K, which is very close to our sun’s 5773 K surface temperature. And it has an iron [Fe/H] abundance very close to our sun at [Fe/H] =0.05 +/-0.08.

Greg

[Fe/H] =0.05 +/-0.08. great: uncertainly greater than the magnitude of the measurement, aka no friggin idea ! ie they don’t even know if there is any iron content !

Tom, not likely. That age is roughly equivalent to one of our “galactic years,” which gives plenty of time for gravitational perturbations from thousands of other stars and rogue planets. You’d have to account for every such disturbance to find an origin. And it’s quite possible it never had a star, but formed directly from a stellar nursery. The rogue may have moons, though. And since it has nearly enough mass to be a feeble red dwarf, those moons would’ve been planets had the rogue sparked off its own nuclear fires.

Slacko

Yep, the possibility of negative iron content is intriguing.

(This was a reply to Greg. How did it get down here?)

First thought that jumped into my mind was “That’s no moon or planet, I have a bad feeling about it” Made me smile.

Reevers… Quick, hide

Clay Sanborn

My understanding is that a planet “is a body that orbits the Sun, is massive enough for its own gravity to make it round [sic], and has ‘cleared its neighborhood’ of smaller objects around its orbit” (per Wikipedia).
Since this object is apparently not orbiting any star (especially our sun), it is not a planet, it is just a celestial body that is large enough for gravity to make its aggregate components into a spherical object. In my thinking, this kind of loose use of language is part of the reason people are confused about almost any topic, including climate. Am I off the rails here?

Theo

That’s the official definition of a planet in a star system.

For bodies of planetary mass orbiting the galactic barycenter, ie rogue planets, the definition is different. Many of them are between Jupiter and red dwarf stars in mass, like this one.

Annie

The name ‘planet’ is derived from the Latin ‘planeta’, ‘wanderer’, so it doesn’t necessarily have to relate to the Solar System, does it?

Theo

Annie,

No, it doesn’t, or shouldn’t (even though the word is ultimately from Greek).

It’s just that historically we started with the known “wanderers” in our solar system (or the “universe” as it was then known). The tricky part is how to extend that term to subsequently discovered celestial bodies both within the solar system and in interstellar space.

jorgekafkazar

Prepare for the nomenclature to change any time some academic can’t think up a paper and has to turn a field on its head to do so.

J Mac

Awwww crap! I haven’t even gotten over Pluto being demoted!
Here we go again….

Michael S. Kelly, LS, BSA, Ret.

Actually, it’s ultimately of Sanskrit.

Annie

I stand corrected…from the Greek.

Red94ViperRT10

Ooooh… because in their (limited) observations from our Earth, the stars stayed pretty much fixed in the sky, but those things that wandered all over the place…!!! Turned out they were orbiting our Sun. But I can see how, sometimes Jupiter appeared in the morning sky right next to the Sun, and sometimes it was completely opposite the Sun and was best observed in the middle of the night! Yeah, those things wandered all over the place!

Rich Davis

I’m just a rebel I guess. No respect for the annointed experts and their official definitions.

Greg

“For bodies of planetary mass orbiting the galactic barycenter”

Nothing outside a two body system “orbits” a barycentre. Barycentres have NO MASS therefore attract nothing. If that is the official definition they need to learn some basic physics.

Next we’ll have Tall Bloke popping up again with his hair brained ideas.

Rich Davis

I tend to think the same thing Clay. It’s an arbitrary definition.

I think that any gas giant that has insufficient mass to start a thermonuclear reaction ought to be considered a brown dwarf regardless of whether they formed in orbit around a star or not. To my way of thinking, Jupiter is a brown dwarf.

Kind of the same pointless argument as the Pluto is or is not a planet question. Arbitrary criteria determine the answer.

Bill Murphy

RE: “To my way of thinking, Jupiter is a brown dwarf. “

Which would make our system a binary, with a G type star and a rather smallish brown dwarf. I recall hearing years ago about an astronomy prof that began his intro lectures about the solar system with “Our solar system consists of the Sun, Jupiter and various minor debris.” Definitions can — and probably should — be somewhat fluid in a field like Astronomy. Arthur Clark apparently thought of it as a failed star and even imagineered an alien technology that could ignite it in his sequel to “2001.”

joelobryan

The problem with the “minor debris” view is Saturn. Saturn has been the key to our system’s stability for the past 4.5 Ga. Its mass and orbital period resonance with Jupiter is what has likely kept Jupiter in a stable position and not wandered inward to the inner planets — i.e. where we live and kicked us out into cold, dark extra-solar space, an ejected planet.

Furthermore, this distance at which Jupiter exerts its influence on the ball of plasma at the center of our system means this ball of plasma is much better behaved than most stars of ~1 solar mass. Most G-class stars that have been observed seem to have high levels of magnetic activity. One way this can happen is if they get “hot Jupiters” pulling on them from close range, unleashing torrents of high magnetic activity on the system.

So Saturn is not some “minor debris” to be unimportant to how our solar system has behaved and evolved. In the same way, the Moon is not just a minor satellite for Earth. The Moon has kept the Earth in a stable obliquity regime, unlike what has happened to Mars, with its wide range of obliquity tumbles.

Bill Murphy

Precisely, Joel. I don’t hold with the “minor debris” idea, I just thought it was an entertaining point of view. As an aside, all the reasons you mentioned plus a few more are why I have little hope for SETI. When I was in school (60’s) we wondered if there were any planets in other systems and the most common view was yes, probably. Based on that and the Drake equation, we talked a lot about the Fermi Paradox, thinking that if planets form often then ours is probably a common type of system. Now that is questionable. The Jupiter Saturn orbital period resonance and the stability it provides would seem to be a low probability event. The several systems that have been discovered with gas giants orbiting at less than 1 AU from their primary confirms this, I think. We have an unusual system here it seems, with gas giants stabilized in the outer system and small planets in close and not being ejected or swallowed by the giants and allowing the Sun to quietly do its thing. Then there is the seemingly highly improbable event of two proto planets colliding at just the right angle and velocity to spin off a Moon of just the right size and orbit to stabilize the resultant planet’s obliquity and for that to happen to leave that planet and moon almost exactly in the middle of the habitable zone of the primary strikes me as hugely improbable. It’s no wonder humans are inveterate gamblers. We are the result of a very unlikely run of sevens on the cosmic craps table.

Um, 2 minor quibbles…

1) Do not forget that our search for other planets uses methods highly biased toward detecting fast orbiting big planets. A planet that crosses the face of its sun once every 200 years would, on average, take 100 years to be seen. One that crosses every year will be seen much sooner. Detection bias for close orbiting large planets is very very large.

2) Planets with high obliquity changes would just evolve more flexible and adaptable life. Our form of life is biased to THIS world. In other conditions you would get other forms of life. Look at polar bears and long hibernation vs pandas and the need to frequently munch bamboo. Different environments, different life.

Maybe at first they are just really slow evolving bacteria living in a dark ocean. Eventually they turn into something like an octupus which uses body and chemical sensors to communicate. Give them a billion years to figure out their frozen water solid sky is hiding a sun and other planets to conquer, and they may already have sent a miniature probe this way to conquer us.

Check out the kind of stars that have gas giant planets at such close distances. In the cases I have heard of, the stars are cooler than the sun and much smaller, usually red dwarf stars. Those stars produce a small fraction as much radiation as the sun does. Also note that gas giants are made mostly of hydrogen with some helium. If Jupiter were at 1 AU from the sun, it would have been eroded by solar wind according to what I have heard.

More accurately about Jupiter at 1 AU from the sun now that I think about this: It would never have formed. Although I suspect that if Jupiter gets moved to 1 AU from the sun, it can survive.

MarkW

The current thinking is that due to interaction with dust and debris, gas giants would naturally spiral in towards their sun.

It is only the gravitational interaction with Saturn that stopped Jupiter from coming all the way into the inner solar system.

Slywolfe

Given enough opportunities, even the most improbable events become inevitable.

joelobryan

If there are enough craps tables, then one will eventually get a run of 7’s.

Theo

Jupiter is definitely not a brown dwarf and far too small to be considered a binary partner of the sun.

The dividing line between a big planet and a brown dwarf is conventionally the deuterium burning limit of about 13 Jupiter masses. Some astronomers disagree with this distinction, however.

Akatsukami

But a brown dwarf can initiate a thermonuclear reaction — it can fuse deuterium. Jupiter can’t; hence the lower limit on brown dwarf mass.

commieBob

… its heat must be leftover from its initial formation some 200 million years ago. So, over time, the planetary goliath will continue to radiate away its warmth.

Or not. The Earth generates a lot of its own heat via nuclear reactions. link How about this giant planet does the same.

Kelvin tried to estimate the Earth’s age by calculating the heat lost since its formation. He got it very wrong. link Every self-respecting astronomer should know that.

Whoever wrote the article got it wrong. If it was an astronomer, for shame. If it was a professional writer, I’m surprised that she would think of that.

Theo

Brown dwarfs, being almost stars, actually generate a lot of their own heat. Depending upon mass, they can fuse deuterium and lithium.

However, brown dwarfs, while only marginally larger than Jupiter, are much denser.

joelobryan

“radioisotope decay” would be a more precise term than “nuclear reactions” in Earth’s core heating process.

TDBraun

That was my thought too. It seems they are estimating the age of it based on what they assume to be the residual heat leftover from formation and radiating away, but it might still be generating its own heat somehow and be much older. !?

Theo

Its age can be inferred from the fact that it belongs to a group of very young stars. Last year, another team of scientists from the VLA team discovered that SIMP J01365663+0933473 belonged to this group.

What’s a planet?

Personally I don’t much care whether we call Pluto of planet, a plutoid, or Mickey’s dog. The word planet is derived from Greek meaning something like wanderer. To the ancients there were the fixed stars and usually 7 wanderers they were; The Sun, the Moon, Venus, Mercury Mars, Jupiter, and Saturn. As we began to understand our solar system better the Sun and Moon were dropped from the definition. In the last couple centuries Uranus, Neptune and Pluto were added. So we’re not the first generation to tinker with the definition but we are the generation beginning to discover all sorts of strange objects not only in our system but beyond as well. The term planet is pretty strongly rooted in our languages thus it will probably survive in common usage. Science however should probably find another word. There exists in our universe a continuum of objects from dust grains to the most massive stars (incidentally black holes are probably candidates for inclusion) which we try to categorize as planets, moons, planetoids, Brown dwarfs, stars and God only knows what else. Perhaps it is time to simplify all this. I propose the use of the term mascon for mass condensation or concentration if you like. I know that the word has already been used as mass concentration to denote concentrations of heavier minerals within the body of planet or Moon which affect the distribution of the body’s gravitational field. It would not however be the first word ever to have more than one meaning. The word would be used with qualifying terms like “secondary non fusing gas mascon” which would be a gas giant like Jupiter, or “primary fusing mascon” like our Sun, or “tertiary rocky mascon”, our Moon “binary fusing mascon”, an element of a double star system. Jbs Haldane wrote “the universe is not only queerer than we suppose, but queerer than we can suppose”. Thus I’m sure will find objects which cannot be classified this way but this system will take us a lot farther and than the old. Some people insist that we must take into account an objects accretionary history. I am not sure that’s a good idea; just describe them as we see them.

Just a few of the oddities out there;

http://www.space.com/scienceastronomy/070806_largest_exoplanet.html

http://www.space.com/scienceastronomy/080410-cold-brown-dwarf.html

We cannot go on coming up with more names (plutoid, planemo, brown dwarf, sub brown dwarf, twin planet , ad nauseam). Name an object and you will find (or will some day find) an object that blurrs the the distinction between it and some adjacent type of object. What happens when we find a stellar mass super high metallicity mascon You are perfectly free to keep your precious names for common use but science needs a new classification scheme.

Theo

Might I suggest paragraphs?

For the nonce, “rogue planet” aptly describes the class of large, spherical objects with substellar mass which orbit the galactic barycenter, IMHO, of whatever provenance.

Roger Collier

Mascon? Just call it a figment as most of its claimed properties are imagination.

Wouldn’t a Dyson sphere have to be much bigger? For our solar system, the sphere would need to be the size of the earth’s orbit.

“an emerging consensus that rapid rotation may be important for producing strong dipole fields in convective dynamos, and/or (ii) rapid rotation is a key ingredient for driving the current systems powering auroral radio emission.”

This is far from my field, but still I’m surprised this is an “emerging consensus.” I would’ve thought decades of magnetohydrodynamic (MHD) simulations and basic understanding of Maxwell equations and fluid dynamics, and further put on solid theoretical grounds by Hannes Alfvén in the 1940’s-50’s, would have put this understanding as solid acceptance 40 years ago.

But then Wikipedia does say this about Hannes Alfvén:

“He was regarded as a person with unorthodox opinions in the field by many physicists,[9] R. H. Stuewer noting that “… he remained an embittered outsider, winning little respect from other scientists even after he received the Nobel Prize…”[10] and was often forced to publish his papers in obscure journals. Alfvén recalled:

“When I describe [plasma phenomena] according to this formalism most referees do not understand what I say and turn down my papers. With the referee system which rules US science today, this means that my papers are rarely accepted by the leading US journals.

Looks like Hannes Alfvén had his battles too with the science journals’ pal review system even 40 years ago.
I think I need to go find this mini-bio and read it: Hannes Alfvén, “Memoirs of a Dissident Scientist”, American Scientist, Volume 76, No 3, May–June 1988, pp. 249–251. Quoted in Joseph Paul Martino, Science Funding: Politics and Porkbarrel 1992, Transaction Publishers, ISBN 1-56000-033-3

bonbon

Hannes Alfven of the plasma universe fame had star formation involving self organizing vortex filaments. How a wandering “planet” like this could be accounted for is a good question.

Strangely enough Alfven got involved in opposition to Reagan’s Mutually Assured Survival with other Pugwash veterans at CERN.

The Kennedy Assassination: what really happened (new, 2018)
https://www.youtube.com/watch?v=ihnqSyUF8pY

“Prof. Jerry Kroth’s talk on the 50th anniversary of the assassination presents the single, most plausible theory of the assassination. It is based on the admissions of grassy knoll gunman, James Files, the deathbed confession of CIA spymaster, E. Howard Hunt, and the most recent scholarship to appear in the last decade. Dr. Kroth proposes that Lyndon Johnson, the CIA, and Mafia, acting in concert, carried off one of the greatest crimes in American history. This talk comes from his latest book, Coup d’etat: The assassination of President John F. Kennedy. It is a concise, well-documented expose of a brazen overthrow of the United States government on November 22, 1963.”

President Donald Trump released 50,000 documents about the murder of President John F Kennedy.

Yet, eye witnesses SAW LHO in the window in the SBD building … WHY would the CIA involve such a life-long SCREW-UP like LHO in an operation like this?

Gerald Posner and not just a few others still posit LHO as the ONLY individual involved in the JFK assassination.

Did you know, for instance, that LHO took a shot at General Walker at his home earlier in 1963? Yup. Bet you never heard that before either …

Did you actually watch the video Jim? It appears not, given the times of our posts.

I am not American and take no position on what actually happened in the JFK case, but there is ample evidence of disinformation. Watch the video.

As an observation, I was badly injured as a kid, and so my only sport for several years was marksmanship. It takes very little skill to be a competent marksman at normal ranges. With a good scope and properly-sighted rifle, you can hit anything you can see.

It gets serious when you are shooting 1km or more – the longest confirmed sniper kill is now about 2.5km, which is pretty good, in a bad sort of way.

Any idea of the distance of the shot that missed Walker?

Are you saying that the same guy who missed Walker when he was stationary was able to kill JFK in a moving motorcade?

re: “Did you actually watch the video Jim? ”

Are you familiar with any of the facts I assert? Are you familiar with any of the known, undisputed facts on this subject?

Sorry, Allan, this has been ‘beat to death’ and there is little in the way of so-called “new” info (and, info that is _not_ necessarily even factual!!) that will sway my thoughts on this subject.

Please find a copy of Gerald Posner’s book “Case Closed” for a reasonable, fact-based view of this subject for starters … Gerald Posner started out being a conspiracy theorist on this subject and had his thinking turned around as he researched material for his book. Vincent Bugliosi also wrote a book on the JFK assassination that might be worth reviewing. My advice, avoid the flashy, conspiracy based movie-oriented stuff and pay attention to the fact-based , well-researched material.

BTW, I live just outside of Dallas, Texas, the epicenter of this ‘event’.

JimG1

Allan,
As a life long competitive shooter and owner of the same model carcano that lho supposedly shot jfk with, I say not likely. A very inaccurate rifle. I have read most of the stuff out there, pro and con regarding the event. Lord knows the CIA, LBJ and the mafia all had plenty of personal and “business” reasons to off the guy, along with more than a few other people.

Thank you JimG1,

As a Canadian, I do not think I should hold a strong opinion on the subject – it is America’s business.

I do remember that day long ago – all too well – I was in high school, the girls were all crying and lots of us boys had a lump in our throats. That and 9-11 were the most memorable days of history in my life.

9-11 victim Meridith Ewart was a kid from my hometown. I knew her family, and she used to babysit my brother’s kids.

I guess I’ve dragged this thread badly off-topic so I will stop now.

Just watch the video. Trump’s release of 50,000 documents is significant.

_Jim

Any idea of the distance of the shot that missed Walker?
Are you saying that the same guy who missed Walker
…”

Uh, yeah. Walker was shot at through … wait for it …. *window glass*. That, alone, never mind the distances involved, can account for a missed or deflected “shot”. See, and more to my point, you didn’t know that _fact_ (the fact that LHO was already attempting assassinations, was already in that mindset), nor the circumstances surrounding it (an attempted shot through a window.)

There is SO MUCH the public has been mislead on, just as in CLIMATE SCIENCE , since it takes time and effort dedicated to searching-out *the facts* and “the trvth.”

DID YOU FURTHER KNOW there were ear-witnesses one floor below Oswald who heard the ‘brass’ hitting the wood floor of the Texas SBD building as Oswald expelled each round after taking a shot? Conspiracy-theory authors DARE not make you, the gullible public, aware of that fact either.

AND don’t forget, I mentioned the EYE WITNESSES who were in cars at the tail end of the motorcade who saw LHO in the **window** of the SBD building as they turned the corner to the right as they entered Dealey Plaza.

There is SO MUCH MORE to this event than you would ever BELIEVE, as you have been fed so much non-factual speculative nonsense from the conspiracy hucksters on the fifty plus years since this event …

FOR REFERENCE, an interview with Vincent Bugliosi

My apologies, too, for taking this diversion from the main topic.

Stephan Fuelling

Not 4 million times earth’s magnetic field. Earth’s magnetic field is about 1/2 Gauss. The rouge planet has a magnetic measured around 5 kG, that’s a factor of ‘only’ 10,000 but still very strong.

Nylo

I wonder how our Sun looked like before it became a star? At some point it must have had a smaller size. We may be watching something that will eventually become a star, some million years later (it must still accumulate way more mass).

Tom Abbott

Good point. It may very well be able to accumlate more mass, depending on its surroundings.

old construction worker

I won’t live that long

MarkW

While it was gaining mass, the sun was surrounded by a very large cloud of dust and gas.

Nylo

Have you ever calculated the average density of the solar system? I.e. divided its total mass between the volume of a sphere of, say, a radius equal to the distance between Sun and Pluto? If a “cloud of dust and gas” of the same mass and volume was surrounding this rogue planet I don’t think we could see it from here. It was already hard to see this really huge planet.

dudleyhorscroft

Obviously this is just bringing out the true saying that fact is stranger than fiction. This massive rogue planet is surely powered and directed by some of our solar systems survivors, who took the planet from the asteroid belt 200 million years ago (the asteroids are the remnants that broke off when the planet moved).

We have the evidence in some SF stories – I forget the titles) regarding the invention of the “Spin Dizzy” which enabled cities to detach themselves from earth and go wandering the Universe. Simp would have nicely balanced Jupiter and Saturn. The waterless state of Mars is evidence that the inhabitants of Simp took the water of its nearest neighbour to supplement its own supplies.

The alleged high temp is surely the observed radiation from the Spin Dizzy Field, or alternatively perhaps an artifice to fend off pirates from other wandering cities which may wish to have a bash at plunder, rape and ravishment. (This last sentence is SARC.)

Hocus Locus

I found this speculative comment mentioning spindizzys with a score of -1, which demonstrates that human driven scoring is a corrupt enterprise. Used my vote to restore it to 0.

Red94ViperRT10

(This last sentence is SARC.)

Just the last sentence? You must grade on a curve. 😀

“What City had two names, twice?”
I think this was the ‘Cities in Flight’ series.
Written by James Blish?? Perhaps.
IIRC. I may be wrong.

Auto
Yes, – see ‘below’. Not reading to the end . . . . . . .

dudleyhorscroft

I had a thought, when in doubt check Google. Yes, it came up with the answer.

“The Dillon-Wagoner Graviton Polarity Generator, known colloquially as the spindizzy, is a fictitious anti-gravity device imagined by James Blish for his series Cities in Flight. This device grows more efficient with the amount of mass being lifted, which was used as the hook for the stories—it was more effective to lift an entire city than it was to lift something smaller, such as a classic spaceship. This is taken to extremes in the final stories, where an entire planet is used to cross the galaxy in a matter of hours using the spindizzy drive.”

Logical that extreme efficiency would be developed with a planet 1.2 times the mass of Jupiter. In 200M years they could easily reach 20 light years away.

My case rests!

Slywolfe

“… 12.7 times the mass and 1.2 times the radius of Jupiter…”

Michael S. Kelly, LS, BSA, Ret.

One million times Earth’s magnetic field would put it at about 32 Tesla. That’s 2.5 times the field strength of the ITER fusion machine!

We will never be able to perform manned exploration of such a planet. It would erase all of our credit cards.

Man Bearpig

Just a question, if it is nomadic, how do the Auroras develop ?

Gamecock

Wondering . . . what’s it made of? Cheese? To be a brown dwarf – a didn’t quite make star – it has to be made of light elements, like hydrogen. If it’s made of iron-nickel, for example, it was never going to be a star even if it were much bigger.

‘its heat must be leftover from its initial formation some 200 million years ago.’

Plus or minus a billion. How the heck do they know how old it is?

Theo

As noted above, its age can be inferred from the fact that it belongs to a group of very young stars.

Last year, another team of scientists from the VLA team discovered that SIMP J01365663+0933473 belonged to this group.

Edward Joseph

My first thought was, “Why is this on a climate site?”

Mark - Helsinki

“However, it’s important to note that Venus gets most of its heat from the Sun. And since solitary SIMP is not orbiting a star, its heat must be leftover from its initial formation some 200 million years ago. So, over time, the planetary goliath will continue to radiate away its warmth.”

The fact they even utter an age of this thing makes be piss myself laughing. It could be 2 billion years old, where do they get this gibberish

“Failed star” lol
The mass needed is proven invalid. Stars seen to form with 20% of mass required in surrounding space. #notjustgravity #filaments #EM

beng135

It could be 2 billion years old, where do they get this gibberish

I wondered about that too. Perhaps they’re guessing the age from the temperature (assuming that it cools at a certain rate from an initial formation temp).

Red94ViperRT10

But how did they determine that rate? Not enough observations yet, I don’t think, particularly if they got the same measurement this time around as they got when they first detected it 2 years ago. Yeah, that difference is, ummm… zero, thus the rate calculates out to… 0°/2 years. Or 0°F/year. Or 0°C/millennium. Or any units you want to use, it’s still 0.

john harmsworth

I assume they received a consensus opinion from leading climate scientists as to how long it would take for this body to heat to its observed temperature if it managed to accrete even a single molecule of CO2.

Theo

As noted above, its age can be inferred from the fact that it belongs to a group of very young stars. Last year, a different team of scientists from the VLA team discovered that SIMP J01365663+0933473 belonged to this group of new stars.

Theo

Mark,

The “electric universe” is gibberish. As antiscientific garbage, it’s generally moderated on this blog. I’m surprised that you’re able to spew it here. Mods have stated that’s the policy, since allowing gravity deniers to comment here would discredit the site.

Below I’ve mentioned one way in which they can estimate the planet’s age.

Yes, but it’s atmosphere must be 1000 percent CO2 with temps like that. (/s)

Bruce Cobb

Uh-oh, these rogue planets can’t be allowed into our solar system. There’s no telling what kind of mischief they’d cause. We’ll need a really big wall. Make the Klingons pay for it.

MarkW

How do they determine size and mass of rogue planets?
The only way I know of to determine mass is to measure how much it influences another body and there’s nothing within light years of this rogue planet.

I can think of only two ways to measure the size of a stellar body. The first is for it to be resolved as a disk, rather than just a point of light in a telescope. This object is either a planet or a brown dwarf, so you couldn’t use optical telescopes for this purpose. Would a radio telescope have that kind of resolution?

The other way is to have the body eclipse a star. It’s one thing for a body in orbit around a star to eclipse it, It’s another thing altogether to have a rogue planet eclipse a star. Even if you did get an eclipse, you would still need to know the speed the body was travelling at.

Theo

The rogue planet lies in a group of very young stars.

Eric Gisin

I was going to ask that. The only things they know are temperature, approx age, and emissions (mostly IR). Maybe there’s a formula for brown dwarfs they use.

Theo

That’s right. They base their estimate on comparison with known brown dwarfs and rogue planets for which good data are available.

eyesonu

From the link provided:

“….. but most importantly, this new research opens the door to future insights into exoplanetary magnetic fields and auroras, as well as aids in the hunt for exoplanets that apparently like their privacy.”

——–

Well, that rogue bad boy is not coming our way. Deep space state is already intercepting their radio transmissions. Next will be summons to appear for Russian collusion. Google and Facebook will apply algorithms that will keep it from being seen. Just like in the ‘artist’s conception’ it will be wearing a striped suit. If it wants its privacy it will stay away from the interstellar government and the new and upcoming IPCC (Interplanetary Panel on Cosmic Control).

J Mac

It’s the planet Vogsphere! Beware the Vogons and their intergalactic highway construction project for a hyperspace express route!

Red94ViperRT10

John Endicott

Beware their poetry even more so.

Doug Proctor

So, at some orbiting distance, a spaceship colony would be awash in a perfect radiant heat and looking at a red-glowing “sun”. Spin the station for 1 g gravity. Science fiction story, anyone?

ralfellis

Rather than being bizarre, I would imagine these soliton planets are very common in the galaxy.

Think about it – stars formed in all sizes, and this just happens to one of the smallest. So small, in fact, that it could not ignite. And since there are many more smaller stars than large stars, one might suggest that there are many many more of these unignited stars (or planets) roaming the galaxy.

Its just that you cannot see them.

R

Theo

A reasonable inference, given the plenitude of red dwarf stars.

comment image

Comparison: most brown dwarfs are only slightly larger than Jupiter (10–15%) but up to 80 times more massive due to greater density. The Sun is not to scale and would be larger.

dan no longer in CA

This is a serious question: Presumably, there are many of these but difficult to detect. What density of them would be required to change the estimate of the universe’s expansion from open-ended to expand-and-contract?

Theo

Probably aren’t enough.

However, primordial black holes, possibly.

I agree it makes sense that large rogue planets should be common and probably more so than rogue brown dwarfs. They also are likely to come in binary and trinary arrangements just like stars and should have their own smaller planets or moons in tow as well, just like Jupiter.

They should be visible at the infrared wavelengths near those corresponding to the ~800C surface temperature. The artist concept image that was provided with the story cannot be accurate for human eyes. It falsely shows an illuminated side, even though there is not a nearby star to illuminate it. To human eyes it would look like a black hole in the starry background with a halo. It would block the light of the stars behind it but produce no light visible to the human eye other than from the auroral rings near each pole and probably lightning that could be seen at closer range.

etudiant

What is this interesting object made of?
As described, about twice the volume of Jupiter with over 12 times the mass, it would be about as dense as iron, while Jupiter and the sun are both only a little denser than water.

Is it wrong that the first thing that comes to mind is, “That’s no moon!”

Also, I don’t suppose anyone is familiar with the story line told through the Final Fantasy computer gaming franchise. (The video is cued to the place that gives the 10-second explanation. And remember – it is based on a video game)

RoHa

It’s Nibiru! We’re doomed, again.

Gordon Dressler

Sorry to report, but this IS most probably a Galactic Empire Death Star (aka DS-1 Orbital Battle Station, v2.0) out there looking for a target.

Thus, the incredibly strong magnetic field of this “planet” is easily explained—as are the “spectacular aurora”—as nothing more than side effects of periodic operational readiness checks of the battle station’s kyber crystal-powered, planet destroying Superlaser, v4.7.

It’s very unfortunate that our EM emissions of 20 years ago have reached them by now.

Planet Alexa

NW Sage

Was Star wars right? Is this the true ‘death star’? Is it coming for us if we don’t bow to climate change? (sarc for those with no sense of humor)

flow in

” its heat must be leftover from its initial formation some 200 million years ago. So, over time, the planetary goliath will continue to radiate away its warmth.”

Is a bit of a massive assumption. Given its strong magnetic field, it is not beyond imagination to consider it another example of a hollow planet with a plasma core (like the earth and most planets in our system)

J. Carroll

You know, when things like this are reported on by Alex Jones at InfoWars, big media kooks and shills declare “rogue planets” are just ‘conspiracy theories.’ It’s absolutely nutty.

J.L.

“Just 20 light years away”? Isn’t Alpha Centauri our
nearest star system neighbor only 4 light years out?
I hope they learn from it but it’s kind of
“far out, man”.

Peta of Newark

Took a while but I’ve worked it out:
Recall the hoo-ha recently about Gravity Waves – supposedly one black hole eating another and came with the revelation that Gravity Waves propagate at the speed of light.
This is patent bollox as it means Gravity is an electro-magnetic phenomenon and hence, by definition, there should somewhere easily visible exist: Anti-Gravity.
Show me pictures…….

Read about this object and it is stonkingly magnetic.
So, if something like this fell into even just an ordinary star, its magnetic effect on local and distant space would change, and sensitive & distant little objects made of a magnetic material would feel the influence of that change.
A change which would, being magnetic, propagate at light-speed.

Planet Earth being made of iron is that sensitive little magnetic detector and THAT is what the Gravity Wavers saw, magnetic ripples (a splash basically) in space created as an object like this came to some less-that-magnetic end.
No need for Black Holes or other wild speculations.

My God, has Climate Science got something to answer for – it’s driven the place completely mad.
But there again, which came first?
Did something (else) start the mental aberrations and Climate Science is the bastid child of *that*

I say sugar in our diet – any better suggestions?
