Astronomy Picture of the Day: Tagging Bennu
October 22, 2020

Tagging Bennu On October 20, after a careful approach to the boulder-strewn surface, the OSIRIS-REx spacecraft's arm reached out and touched asteroid Bennu. Dubbed a Touch-And-Go (TAG) sampling event, the 30 centimeter wide sampling head...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Friday, October 23, 2020 6:20:20 am CDT
Julian Date:2459145.97245
Local Sidereal Time:07:03:52.5

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.

Daylight on Friday, October 23, 2020 in Paul J. Feder Observatory
Solar Day (Sun Rising/Setting)7:55 am CDT6:25 pm CDT
Astronomical Day (Darkest Skies)6:13 am CDT8:06 pm CDT
You can click on the "ICAL" button to the right to download an iCal file with the Sunrise and Sunset times for the next year (iCal files should be compatible with Mac OS X iCal or Microsoft Outlook).

  1. Astronomers Challenge Recent Findings About Venus. “No Statistically Significant Detection of Phosphine” (Thu Oct 22 6:52 pm)
    In September, a team of scientists reported finding phosphine in the upper atmosphere of Venus. Phosphine can be a biomarker and is here on Earth. But it's also present on Jupiter, where it's produced abiotically. The discovery led to conjecture...
  2. Scientists Think They Know What Caused the Deadliest Mass Extinction in the History of the Earth (Thu Oct 22 4:42 pm)
    Humanity can have a love/hate relationship with itself, but there's no denying that we?re the pinnacle of evolution on Earth as things stand now. But it took an awfully long time for evolution to produce beings such as we. Several times, life...
  3. Weekly Space Hangout: October 21, 2020, Dr. Jill Tarter and the Search for Technosignatures (Thu Oct 22 2:53 pm)
    This week we are excited (and honored) to welcome Dr. Jill Tarter to the Weekly Space Hangout. Best known for her work in the field of SETI, tonight Jill will be discussing the search for technosignatures. Dr. Jill Tarter is the Emeritus Chair...
  4. Tales of Two Fall Comets: 88P Howell and M3 ATLAS (Thu Oct 22 12:18 pm)
    Two more comets worth scouting the sky for into November 2020. The post Tales of Two Fall Comets: 88P Howell and M3 ATLAS appeared first on Universe Today.
  5. What Would a Realistic Space Battle Look Like? (Wed Oct 21 5:30 pm)
    Science fiction space movies can do a poor job of educating people about space. In the movies, hot-shot pilots direct their dueling space ships through space as if they?re flying through an atmosphere. They bank and turn and perform loops and...
