Comet NEOWISE now visible in the evening sky

First, there was Comet ATLAS in April which disappointed sky watchers as it broke apart into pieces. Then there was Comet SWAN in May which also disintegrated. And now we have a third comet named NEOWISE and this one is coming through. In recent days, this comet has been visible shortly before sunrise, but now, it has become an evening object as well and will actually be visible at both ends of the day for the rest of this week.

Morning (soon to be evening) Comet Neowise Timelapse

Dr. Roy Spencer writes on Facebook: We finally got some dry air in N. Alabama, so I captured ~900 photos of comet NEOWISE starting about 3:45 this morning from the Monte Sano east overlook, using 2 cameras, one wide angle (30mm) for landscape shots and one telephoto (200 mm) for time lapse. Time lapse video…

Some Random Quantum Thoughts

Guest post by Rud Istvan This guest post was inspired by a long delayed lunch (by Covid-19, with our first two traditional restaurants found still closed for lunch by Wuhan virus fears despite now open South Florida) between CtM and myself. We discussed much, including WUWT. I complemented Charles on the recent months more eclectic…

New distance measurements bolster challenge to basic model of universe

Observational results inconsistent with theory National Radio Astronomy ObservatoryShare Print E-Mail A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that theorists need to revise the “standard model” that describes the fundamental nature of the Universe. The new distance measurements allowed astronomers to refine their calculation…

Brightest-ever supernova discovered

A supernova at least twice as bright and energetic, and likely much more massive than any yet recorded has been identified by an international team of astronomers, led by the University of Birmingham. The team, which included experts from Harvard, Northwestern University and Ohio University, believe the supernova, dubbed SN2016aps, could be an example of an extremely rare ‘pulsational…

How Mars lost its water to space

How the sun pumps out water from Mars into space Russian and German physicists have offered an explanation for the new data obtained by Martian satellites, capturing the “escape” of hydrogen atoms from the upper Martian atmosphere into outer space. The developed model fits well with the observations and explains a number of puzzling phenomena…

Planning for the ‘Earth shattering kaboom’

NASA, FEMA, International Partners Plan Asteroid Impact Exercise While headlines routinely report on “close shaves” and “near-misses” when near-Earth objects (NEOs) such as asteroids or comets pass relatively close to Earth, the real work of preparing for the possibility of a NEO impact with Earth goes on mostly out of the public eye. For more…

NASA has a plan defend the Earth from asteroids

The trick is spotting the near-Earth objects first, according to NASA researchers presenting at the 2019 American Physical Society April meeting in Denver WASHINGTON, D.C., April 16, 2019 — A mere 17-20 meters across, the Chelyabinsk meteor caused extensive ground damage and numerous injuries when it exploded on impact with Earth’s atmosphere in February 2013.…
