Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Friday, July 23, 2021 7:16:28 pm CDT
Julian Date:2459419.51144
Local Sidereal Time:13:58:27.6

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. Scientists Have a new way to Predict the Most Damaging Solar Storms (Fri Jul 23 10:08 am)
    Space is full of hazards.  The Earth, and it's atmosphere, does a great job of shielding us from most of them.  But sometimes those hazards are more powerful than even those protections can withstand, and potentially catastrophic events can...
  2. Micrometeorites Churn up the Surface of Europa. If you Want to Find Life, You’ll Need to dig Down a Meter or So (Thu Jul 22 8:13 pm)
    According to new research, impact craters caused by micrometeorites are the best place to look for evidence that life exists beneath Europa's icy shell. The post Micrometeorites Churn up the Surface of Europa. If you Want to Find Life, You?ll...
  3. Neutron Stars Have Mountains, They’re Just a Fraction of a Millimeter High (Thu Jul 22 8:53 am)
    The universe has some very extreme places in it - and there are few places more extreme than the surface of a neutron star.  These ultradense objects form after a supergiant star collapses into a sphere about 10 kilometers (6 miles) in diameter. ...
  4. Here are the First New Pictures From the Fully Operational Hubble (Wed Jul 21 3:50 pm)
    The astronomy community breathed a huge sigh of relief earlier this week when the Space Telescope Science Institute announced the Hubble Space Telescope's major computer issues had been fixed. In a grueling month of recovery work, every expert...
  5. Ions Surf Through Jupiter’s Magnetic Field, Triggering its Auroras (Wed Jul 21 7:19 am)
    Auroras come in many shapes and sizes.  Jupiter is well known for its spectacular complement of bright polar lights, which also have the distinction of appearing in the X-ray band.  These auroras are also extreme power sources, emitting almost...

  1. China's carbon-monitoring satellite reports global carbon net of six gigatons (Thu Jul 22 11:00 pm)
    (Institute of Atmospheric Physics, Chinese Academy of Sciences) About six gigatons -- roughly 12 times the mass of all living humans -- of carbon appears to be emitted over land every year, according to data from the Chinese Global Carbon Dioxide...
  2. Dalian Coherent Light Source reveals strong isotope effects in photodissociation of water isotopolog (Thu Jul 22 11:00 pm)
    (Dalian Institute of Chemical Physics, Chinese Academy Sciences) Scientists revealed strong isotope effects in photodissociation of the water isotopologue (HOD) using the Dalian Coherent Light Source.
  3. $1M NASA grant to improve carbon monitoring in East Africa (Wed Jul 21 11:00 pm)
    (Cornell University) Cornell University researchers will develop the first high-resolution carbon monitoring system for East Africa that combines "bottom up" ecological modeling with "top down" satellite data, thanks to a three-year, $1 million...
  4. Gaming graphics card allows faster, more precise control of fusion energy experiments (Wed Jul 21 11:00 pm)
    (University of Washington) University of Washington researchers have developed a method that uses a gaming graphics card to control plasma formation in their prototype fusion reactor.
