Astronomy Picture of the Day: The Comet, the Whale, and the Hockey Stick
May 13, 2021

The Comet, the Whale, and the Hockey Stick Closest to the Sun on March 1, and closest to planet Earth on April 23, this Comet ATLAS (C/2020 R4) shows a faint greenish coma and short tail in this pretty, telescopic field of view. Captured...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Thursday, May 13, 2021 11:23:43 pm CDT
Julian Date:2459348.68314
Local Sidereal Time:13:26:27.8

The following sunrise/sunset times are for Paul P. Feder Observatory at Buffalo River State Park, about 14 miles from the MSUM Campus. They are only accurate to about 3 minutes since no attempt has been made to deal with the effects of changing temperature/humidity on atmospheric refraction. However, they should be reasonably accurate anywhere in the Fargo-Moorhead area.

  3. Extrasolar Object Interceptor Would be Able to Chase Down the Next Oumuamua or Borisov and Actually Return a Sample (Thu May 13 1:21 pm)
    What if we had the ability to chase down interstellar objects passing through our Solar System, like Oumuamua or Comet Borisov? Such a spacecraft would need to be ready to go at a moment's notice, with the capacity to increase speed and change...
  4. A Comet Seen at the end of its Life. It’s covered in talcum powder (Thu May 13 1:03 pm)
    Astronomers finally managed to observe a comet nearing the end of its life. And they found that it's covered in talcum powder. They have no idea why. It's usually very tough to observe the nucleus of a comet. When comets come close enough to...
  5. Gaia Might Even be Able to Detect the Gravitational Wave Background of the Universe (Thu May 13 8:32 am)
    Data from the Gaia satellite is so precise, it might be able to detect cosmic gravitational waves. The post Gaia Might Even be Able to Detect the Gravitational Wave Background of the Universe appeared first on Universe Today.
