NASA will host a teleconference at 2 p.m. EDT Monday, Sept. 26, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa.

Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa. Participants in the teleconference will be:

  • Paul Hertz, director of the Astrophysics Division at NASA Headquarters in Washington
  • William Sparks, astronomer with the Space Telescope Science Institute in Baltimore
  • Britney Schmidt, assistant professor at the School of Earth and Atmospheric Sciences at Georgia Institute of Technology in Atlanta
  • Jennifer Wiseman, senior Hubble project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland

To participate by phone, media must contact Dwayne Brown at 202-358-1726 or dwayne.c.brown@nasa.gov and provide their media affiliation no later than noon Monday.

Audio of the teleconference will stream live on NASA’s website at:

“Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa,”

That gives a wide latitude, it could mean anything from discovering plate tectonics like we have on Earth, to discovering what looks like algal type blooms that discolor sections of the frozen ocean based on seasonal changes.

Astrobiologists have long regarded Europa as one of the solar system’s best bets to host alien life. So did Arthur C. Clarke in his followup story to 2001, A space Odyssey with 2010: Odyssey Twowhich is where that famous “attempt no landing there” phrase comes from. Europa is a 1,900-mile-wide (3,100 kilometers) moon of Jupiter that apparently holds a huge ocean of liquid water beneath its icy shell; furthermore, astronomers think this ocean is in contact with Europa’s rocky mantle, making possible all sorts of interesting chemical reactions that could create life, much like what we witness near deep sea hydrothermal vents in Earth’s oceans.

What is most interesting is that the scientists that run the JUNO probe don’t want to let it crash land there like has been done on so many other moons and planets. They don’t want to risk it contaminating the moon.

NASA did say this in response to some outlandish speculation:

We’ll be watching with great interest.

      • BTW, I don’t know what this was supposed to mean:
        From the “ALL THESE WORLDS ARE YOURS—EXCEPT EUROPA ATTEMPT NO LANDING THERE” department.

        There is a very good reason for not touching Europa if we suspect there maybe some form of life there since it would pretty much nullify any findings if we contaminate it first. Like the lake under Vostck in Antarctica.

      • @Greg: This was a cultural reference you seem to have missed.

        Stanley Kubrick’s 1968 version of “2001: A Space Odyssey” became famous with its image of monkeys dancing in front of an alien monolith while “Also Sprach Zarathustra” fills any mental voids with tympanic reverberation. However the “ATTEMPT NO LANDING” quotation comes from the sequel, “2010: Odyssey Two,” where a follow-up expedition heads out to the Jovian system to figure out what happened to Dave & the HAL9000 those many years before.

        Of the two films, I find “2010” to be nearly as pretty & far easier to watch than “2001,” even given its dated nature (filmed in the late 1980s to depict an era 25 years later). Also, one doesn’t NEED to see the first to enjoy the second, as it stands alone fairly well. I understand this is probably heresy, and accept that all the Internet’s pitchforks & torches, tar & feathers will shortly be following their optimal ballistic intercept trajectories with my own current vector…. now-ish. ^_^

      • I evoke my inner Arthur C Clark and predict NASA is going to announce “Something Wonderful”

        Perhaps they’ve found a monolith on Europa

      • Stanley Kubrick can burn in Hades as far as I am concerned for destroying forever, that marvelous Tone Poem by Richard Strauss.

        Just as Walt Dismal, and Leopold Stokowski murdered Beethoven’s Pastoral Symphony, as well as J.S. Bach’s Toccata and Fugue in D-Minor, in Fantasia. Well that movie was a disaster for all of the pieces of music it featured.

      What surprising news ??

      I read all about that yesterday on WUWT.

      Europa Seas are so yesterday !

      g

      I read a

      • More seriously;

        If my memory serves me correctly, a pseudo weirdo guy by the name of Richard C. Hoagland; or close to that, proposed YEARS ago, that Europa might have liquid ocean underneath its ice, and that NASA should consider sending probes there.

        As far as I know, NASA has never acknowledged the origin of that idea.

        Hoagland used to be a regular on the Art Bell late night radio program, which eventually morphed into the George Noori program.

        Hoagland was always talking about some total BS stuff he called “Hyper Dimensional Physics” and what problems he has solved using that; but so far as I know he never ever published any papers on any examples of his HDP calculations of anything.

        He also had some fetish about 19.something degrees, as in a Latitude of something somewhere; or more often about everything that popped up at 19.something latitude.

        And I believe that there is a published paper from him on his Europa liquid oceans postulate, that dates back to when he first proposed the idea.

        I always thought he was a kook, somewhat in the Mucho Kookoa vein; but then there was his Europa liquid Oceans suggestion offsetting that.

        G

      • @ george, re Hoagland: Just because an idea originates with a crackpot doesn’t necessarily mean the idea itself is crackpotty.

        Copernicus was a crackpot (obsessed with restoring the “perfection” of circular movement to Heaven, the physics be damned) who just happened to be right . . . or, well, to have a more workable model.

      • “””””…..

        More seriously; …..”””””

        So where did I say it was a crackpot idea ??

        I was noting simply that Hoagland should be credited with having first proposed this idea, and being roundly ignored.

        Yes I think he is nutty; but he wrote a serious paper describing his theory, and they just thumbed their noses at him.

        I don’t; and I still think he is nutty.

    • Since one of NASA’s primary missions now is “Muslim outreach”, maybe they’re still translating the texts? Not easy, must be sensitive to Muslim sensibilities, and politically correct, you know.

    • The water vapor fountains are old wood, now. NASA have to come up with something really SURPRISING now. My bet is one of three possibilities:
      1) Organic compounds in the vapor jets, for example CO2, CH4, C2H6, and PAH
      2) Non-organic compounds, like for example: NH, NaCl, etc
      3) Metallic compounds, like Cu, Zn, Fe, etc

      Why? Yes, because there is also heat inside this globe, induced by tidal forces, and that means hydrothermal activity, where these compounds are produced – also on Earth, Titan, etc.

      Lets get the popcorn out for the big event….

  1. That’s interesting and all, but this being Watts up With That I automatically thought about headlines next week being something like “Global Warming is Melting Europa’s Icy Crust”. =)

  2. Big jump from algae to life is easy just as it’s a big jump to think it’s independent from Earth. Who’s to say some big rock blown off of the Earth did not already contaminate Europa?

    • Btw, how deep would that deadly radiation penetrate the ice and possible water on Europa? If I recall, water is a big time stopper of various types of radiation.

      • A half value layer for water is about 8 inches… Could be less or could be more depending on the type of radiation and energy, there are several factors involved but, 8 inches is a good rule of thumb. It takes about 5 half value layers to stop 99%+ of radiation. So, you would need about 40 inches of water… Give or take a little bit.

      • Ice doesn’t work quite as well as a radiation shield, but liquid water is exceptional; even with NO surface ice on Europa, the hard radiation of space AND the radiation of the massive Jovian magnetic fields would be damped to Earth sea-level norms within just a few meters of the surface, as SMC previously indicated.

        This is why on-site nuclear reactor waste is stored in containment pools: (with permission from all the guys with guns guarding the place, of course!) you would likely get a lower dose of radiation swimming in the upper layers of such a pool than you do just walking outside.

      • Research reactors are often Pool Type, the guts just sit on the bottom of a swimming pool like tub… and you can look down through the water when they are operating… Containment? We don’t need no steenking containment! !! Or shielding beyond the water.

      • @george e. smith, who said: “What deadly radiation ??”

        George, just as Earth has an active magnetic field, and thus belts of charged particles (the Van Allen belts), Jupiter has a much larger, more powerful magnetic field, one which would appear almost five times the size of the full moon in our sky (assuming we could see it, of course). Anyone standing/landing/living on the surface of any of the Galilean moons will have to shield against this somehow if they wish not to cook like a fried egg, and quickly! This is why we were mentioning the shielding capability of Europa’s (possible) ocean.

      • What deadly radiation ??

        Deadly Orgone Radiation

        [As opposed to the Deadly Orange Refrigerators of the late 1960’s? …mod]

  3. Spoiler alert: NOT aliens:

    In related news, Donald Trump expressed relief that there were no aliens discovered on Europa. Something about no having to build another wall…

    • In other other news, Hillary expressed dismay at the news there were no Aliens on Europa. “There’s hundreds of thousands of refugees who have fled to Europe,” she said. “What suddenly happened to them? I have a very stern message that I have left for Ms Merkel and other leaders, this just isn’t acceptable.”

      • If they really could get to Europa then both the European Space Agency and NASA would be falling over themselves to offer them jobs!

    • Not aliens you say, David?

      That Fed-ex delivery person is going to be really PO’d when they get to Europa to deliver that t-shirt!

    • Take us to your leader. …. What? A short-timer, a blowhard and a dying grandmother? You don’t say. …. Okay, how about this Rasputin guy, he controls a big chunk, right? …. Oh, he bombed a humanitarian convoy, and he’ll embarrass us, you say? …. Okay, how about this Britain country? …. NO? …. Okay, what’s this European Union thing? …. Oh, that’s disappointing. …. Okay, new plan, take us to these Dave and Buster guys.

  4. Nice way to build up hype, speculation and anticipation. Hopefully the announcement lives up to, or at least is somewhere in the ballpark, people’s expectations.

  5. Polar bear activity, responsible for resupplying the polar bear population on Earth, but now their polar bear supply is running out and it’s worse than we thought.

  6. Nothing NASA could say would surprise me.

    Nothing there …. all the way to humanity came from there….to we’ve already been there…. to super advanced super beings vacation there.

    Nothing will surprise me.

    What might surprise me is if NASA DOESN’T ask for more money to mount an expedition to go there.

    no bucks, no buck rogers…

  7. Perhaps the announcement will be that they have observed “climate change” on Europa. It will be speculated that the Europans have been burning too much methane, causing climate change. Their own version of subversive control by deception, the Europan Union will be asked to curb emissions and forgo personal freedoms to combat “climate change” on Europa.

  8. Dang. Was looking for something really really profound. Water under ice? Oh well.
    It is still interesting that we’ve developed technology to detect such a thing. If that’s all it is.
    Yeti’s home world would have been more fun. With maybe, a Corey Feldman fan club.

    • brantc, whoever photo-shopped those building-shadows on the Europa pic would’ve be more convincing if they had softened the edges just a little bit….

    • OK, looking more closely, maybe those “building shadows” are just artifacts of the processing or data-stream.

  9. OK, wild speculation time. What can Hubble discern about Europa that could betray the behaviour of the supposed ocean? The only thing I can think of is anomalous nutation about its synchronous rotational period i.e. anomalous drag and acceleration from the ocean slopping. I haven’t a clue whether Hubble can see Europa clearly enough to discern this.

      • If there have been water spouts then crashing the probe into it should be fine & who knows, we may be letting The Great A’Tuins child free from it’s tough eggshell ;)

    • Just worked out that the surface rotates about 0.6 m/sec faster at periapsis than at apoapsis so, not much difference. Being only a few percent of the mass, the slosh n drag would add just a few seconds and maybe a km or so of delay on equatorial rotation (informed guess based on absolute upper limit).

  10. You know the punters love all this alien life stuff. Should put another zero on the end of that check. (And remember, no bloody emails saying we can’t find alien life and it’s a travesty we can’t!)

  11. They have built up too much expectation.

    When the news is released, it is bound to be anti climax, just as their last staged press conference was.

  12. If NASA really had astounding info, they would not tease the world about it.

    It would leak!

    Can anyone NOT imagine staffer selling info on “discovery of alien life” to “the media” for 10 million bucks?

    • For some unknown reason your post has inspired me. NASA has discovered Sea Monkeys on Europa. They look exactly like they do in the advertisements in the comic books.

      One sad excuse for a NASA staffer tried to get money by leaking the information to the media but they laughed her out of the office.

  13. I just hope the news from NASA is a bit more exciting than Geraldo Rivera’s two-hour special when he opened Al Capone’s empty vault.

  14. So the idea might be that it actually “snowballed” (unlike earth), including gasses that do not freeze on earth; and its “crust” might be something akin to a frozen atmosphere. The Siliceous material we think of as rock would be the “mantle”, isolated and insulated and capable of imponderable outbursts…

    Cool stuff.

  15. Thanks Anthony, the Jupiter System is pretty cool, with its moons and all.. a subsystem within the Solar system.

    Ran across an article today on how we are now better able to pin point where solar storms will produce/affect ground currents on Earth.
    There is also a link to the technical document, with open access. (new and no paywall, thanks)

    U.S. Sharpens Surveillance of Crippling Solar Storms
    Next-generation space weather model will map the danger facing power grids
    http://www.scientificamerican.com/article/u-s-sharpens-surveillance-of-crippling-solar-storms/
    By Alexandra Witze, Nature magazine on September 20, 2016

    …As early as the end of this month, NOAA should have a much better idea of just how dangerous those electromagnetic storms are. The agency will begin releasing forecasts that use a more sophisticated model to predict how incoming solar storms could fry electrical power grids. It will be the clearest guide yet as to which utility operators, in what parts of the world, need to worry.
    “This is the first time we will get short-term forecasts of what the changes at the surface of the Earth will be,” says Bob Rutledge, lead forecaster at NOAA’s Space Weather Prediction Center in Boulder, Colorado. “We can tell a power-grid customer not only that it will be a bad day, but give them some heads-up on what exactly they will be facing.”…
    …Until now, NOAA had warned of solar activity using the planetary K-index, a scale that ranks the current geomagnetic threat to the entire Earth. The new ‘geospace’ forecast, which draws on more than two decades of research, comes in the form of a map showing which areas are likely to be hit hardest….

    In their latest paper, Love, Pulkkinen and their colleagues describe the most detailed map of these ‘geoelectric hazards’ across part of the United States (J. J. Love et al. Geophys. Res. Lett. http://doi.org/bqpm; 2016). Of the areas surveyed so far, those at the highest risk are the upper Midwestern states of Minnesota and Wisconsin, where complex geology induces strong electrical currents.
    Adding in 3D models of these ground currents will improve the next generation of NOAA forecasts, Rutledge says. “This is by no means the end.”

  16. Does our moon spin or not?

    Given we’re talking about moons I’d like to raise an issue with this free-thinking illustrious group that has really puzzled me. I always understood that our moon does not spin on its polar axis. I can understand clearly, within the context of the 6 degrees of freedom it has in 3 dimensional space how it can orbit earth and still only show one face to our planet. In fact, my understanding if is spun on its axis at any speed whatsoever that it could not show only one side to the earth permanently. Much to my surprise I see that Nasa have on their website the following:

    Misconception: The Moon does not rotate.
    Reality: The Moon does spin on its axis, completing a rotation once every 27.3 days; the confusion is caused because it also takes the same period to orbit the Earth, so that it keeps the same side facing us.

    at http://moon.nasa.gov/moonmisconceptions.cfm

    and plenty of other places on the web saying likewise. However, I call in defence of my position that it does not spin no less than Nikolai Tesla who produced the paper below showing/’proving’ that the moon does not have angular momentum about its polar axis.

    http://www.teslauniverse.com/nikola-tesla/articles/moons-rotation
    http://www.teslauniverse.com/sites/default/files/article_files/19190400-01.pdf

    What gives here? How come Nasa are saying it is spinning? Is this just a frame of reference issue? I find it very intriguing and wonder have I mis-understood the issue entirely as, if I’m (and Tesla!) are correct, then Nasa have made an egregious error here.

    Can anyone enlighten me?

    • Think of a car in a curve. The vehicle doesn’t rotate in relation to it’s respectively movement, in relation to the driven route upon the street.

      Although it rounds the center of the curve.

      • Of course you’re right, hoplit the motion of the moon is simply straight forward :

        steal the earth from the center of the trajectory and the moon moves straight forward, spin around the moons axis long gone.

    • So after the curve that car plain rolls on; and freed from the trajectory around earth, by an outer force, the moon would move straight along, no spin around its axis.

      • Johann, I’m a bit puzzled by what you’re saying as this last point you made substantiates what I am saying. The law of conservation of momentum doesn’t allow the spin momentum to just disappear. The circular motion momentum is preserved in your example in the car continuing along in a straight line. If, as you say ‘no spin around its axis’ after it moves straight along that can only mean it never had spin in the first place. I’m not certain but I think people are confusing circular (but linear) motion with rotational motion.

      • So now let us drive your car around your curve, but we do it on the local ice yachting lake; smooth ice, without spiked tires. Yes it’s a Subaru so it has all wheel drive.

        Will the car rotate now ?? or just sit still in one place ??

        G

    • NASA is right. The fact that you always see the same face and can see it doing phases demonstrates that it rotates relative to the sun, but at a rate matching the earth orbiting speed.

      • EM Smith & Johann – think of the 6 degrees of freedom the moon has: 3 linear (heave, surge, sway) and 3 rotational (roll, pitch, yaw). I contend that the movement of the moon is purely the former three and with no movement in the later three. In order for an object to have movement in the latter three degrees it means it must be moving about an axis that goes through the body itself (centred if symmetrical rotation or off-centred if it’s an irregular spin). If the object is moving about an axis outside of the body only then the object has only linear motion (yes, it is circular but linear motion doesn’t have to be straight lines!).

        The moon has no angular momentum (i.e. it doesn’t spin about any axis internal to its boundary – symmetrical or otherwise). On the other hand the earth has linear motion (orbiting the sun) AND rotational motion (spinning on its polar axis).

        The fact that the moon shows all sides of itself to an observer standing on the surface of the sun does not mean that the moon has rotational motion itself but that it has linear motion around a fixed distance from an external axis and the observer is located outside of the circular (but linear motion) path that it is on.

        Consider the tennis game that was popular 30 years’ ago where a tennis ball was on a 1.5 metre string and it went around a 2 metre pole stuck in the ground. To an observer at the pole the tennis ball always shows the same face (it has to as the string won’t let it spin on its ‘polar’ axis) but to an observer outside the path of the tennis ball (i.e the players of the game) it was showing all sides of the tennis ball as it travels around the pole. There’s no rotational motion (possibly is on the axis described by the line of the string but not on the axis perpendicular to it.

        I note that NASA are saying the spin of the moon and orbit are coincidentally in lock step so we see only one side of it. There’s nothing coincidental here – the moon isn’t spinning on its polar axis at all.

    • Another way to think of linear and rotational movement is as follows:

      1. Linear straight line motion: all atoms in the fixed body are moving in the same direction and at the same velocity
      2. Linear curved motion: all atoms in the fixed body are moving in the same direction but at different velocities (this is why we have to have differential gearing in cars as inside and outside wheels move at different velocities around corners)
      3. Rotational motion: atoms in the fixed body travelling in different directions and at different velocities.

      A fully free fixed body has the following total of 6 combinations of possible movements: 0, 1, 2, 3, 1 & 3 or 2 & 3. 1&2 are contradictory and 1&2&3 are, therefore, also contradictory.

      • So let us take a spherical solid body sitting stationary in free space. No motion of any kind relative to the co-ordinate frame.

        It is not translating, and it is not rotating.

        If I then move it in a straight line in the X direction, it is now translating, but it is not rotating.

        If I move it in a straight line in the Y direction, it is translating but it is not rotating.

        If I move it in a straight line in any direction with a X component, and Y component, it is still translating and still not rotating.

        This is true, no matter how far I move it, and for any Vy / Vx ratio.

        So if I continue to move it in a sequence of interleaved x and y steps, it continues to move and it continues to not rotate.

        What if I move it in four steps of equal x and y but alternating in sign +x, +y, -x, -y ……

        Now it moves around a square path, but it does not rotate.

        That square of side 2a has the equation x^infinity + y^infinity = a^infinity

        Well I don’t like that, so I’ll make it x^n + y^n = a^n where n has any positive value from down to but not including zero, and up to but not including infinity.

        So starting with the Square path case, with translation but no rotation, I now reduce the value of n.

        It will be found that the sides are now no longer straight lines, every point on that pseudo-square path has a finite non zero curvature.

        The body continues to translate, but it never starts to rotate.

        At any time, at any point in the path, I can stop the movement completely. The angular momentum of the object never changes.

        Eventually, I will end up with n = 2.0 ……

        So just when did the object start spinning.

        Any forces applied to the body to get it to move (if such is needed) are applied exactly at the center of this completely symmetrical spherical object, so no torque is ever applied.

        Tesla was at least as bright as Elon Musk; but only just.

  17. If NASA’s pattern holds, the Big Announcement will be a pretty mundane observation followed by extensive fundraising.

    I *hope* it will be something actually interesting, but it would be uncharacteristic.

    Though it is now controversial, we have already gone through the “bacterial life outside of Earth” announcement, so that will be less exciting than some people think it would be.

    Waiting until Monday is just using the news cycle.

  18. Maybe Europa is at war with Titan? The strange cloud recently reported on Titan may be the result of an attack – those water vapor fountains may be the equivalent of ‘chem trails’ from departing missiles! /sarc

  19. I guess I don’t “get it” as to why they don’t land…they have no problem “contaminating” everything else…. For all they knew, there was life on Mars – but they didn’t let that stop them. Just sayin….

  20. Maybe they will announce that they have found the missing heat that was supposedly going into our oceans but was not seen by the ARGO bouys.

    CO2 has many mysterious powers such that anything is possible

  21. It seems pretty clear that there’s intelligent life on Europa, we can see quite clearly that they have a sophisticated network of canals!

  22. Anything short of discovering a black rectangular monolith on thetonynas surface of Europa will be dissapointing

  23. They are probably just going to announce that they need lots of money to study something that they just made up.

    I hate being cynical…. but these are cynical times.

  24. NASA ANNOUNCEMENT RE: EUROPA
    Dear Europan Neighbor,

    Starting Monday September 26th [Earth calendar] technicians will be in your area to demonstrate and and introduce lucky customers our new exciting new line of services, which include 50 premium TV channels, telephone with unlimited free continental long distance, Internet with speeds of up to 0.0001Mbps (pings less than 1.5 hours!) and bonded central alarm security monitoring. If you are willing to let us place a sign your front law you get a cash back bonus! Early signers get no payments for one solar rotation, chances are limited! So don’t stay under the ice… make contact with us today!

  25. Reminds me of the Clinton regime when NASA announced finding “evidence” of life on Mars. Turned out, after the election, to be just oxide deposit like titanomagnitite. Someone should have taken a class in oxide mineralogy.

    Ha ha

    Attempt at National Distraction about Monica Lewinsky and “Cigar Gate”. Remember!

      • And the same party went on to put John Holdren on national TV to pronounce global warming caused the polar votex winter cold with unsupported sources that were withheld with the same stall and delay tactics used on all the other grand standing. That amounts to a pattern of Party stupidity and not just one administration representing it.

  26. I found the inclusion of Britney Schmidt to the panel curious, so looked her up. This probably hints at what the presser is about:

    http://cstar.gatech.edu/britney-schmidt

    “Professor Schmidt’s area of interest and expertise is planetary ices and the early solar system. She is keenly interested in the habitability of icy worlds and collaborates actively with both geophysicists and biologists. From 2007 until present, Schmidt has assisted NASA Science Definition Teams for Europa missions in both assistant and advisory roles and played a key role in developing the recent Europa Clipper and Europa Lander mission concepts. As a fellow and research scientist at the University of Texas, she gained hands-on experience with Earth’s ice shelves, including the use of imaging and ice penetrating radar, to inform future studies of Europa. Her 2011 Nature paper advanced critical hypotheses regarding subsurface beneath chaos terrain on Europa. She is a co-investigator on a topographic imaging instrument selected for development for the future Europa Clipper Mission. She is the principal investigator of Sub-Ice Marine and Planetary Analog Ecosystems (SIMPLE) that will accomplish a comprehensive study of geophysics and biology beneath the McMurdo Ice Shelf using integrated imaging, ice penetrating radar, and subsurface exploration by marine vehicles. She has participated in two Antarctica field seasons, leading SIMPLE’s exploration in 2012, and will again deploy in 2014-2016.”

  27. Presumably they’ll announce that the surface ice is seen to be moving around, so indicating a liquid ocean beneath the surface ice. At the least, some surface features are changing.

  28. They will claim to have found evidence that AGW has spread to Europa. This will distract from Hillary’s mounting woes and of course help fund more of NASA’s budget.
