Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Saturday, October 16, 2021 10:10:32 am CDT
Julian Date:2459504.13231
Local Sidereal Time:10:26:09.1

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.

  1. Rocky Planets Might Need to be the Right age to Support Life (Fri Oct 15 3:45 pm)
    In a new study, a team of Earth scientists shows how scientists could look for signs of a carbon-silicate cycle on exoplanets. The post Rocky Planets Might Need to be the Right age to Support Life appeared first on Universe Today.
  2. Not Just Sitting Ducks. Maybe Satellites Could Dodge Almost all Space Junk (Fri Oct 15 3:15 pm)
    Kessler syndrome is becoming more and more of a potential hazard as more and more companies vie to place more and more satellites in Low Earth Orbit (LEO).  But it will only get out of hand if a chain reaction of collisions happens, which...
