Astronomy Picture of the Day: Confirmed Muon Wobble Remains Unexplained
April 13, 2021

Confirmed Muon Wobble Remains Unexplained How fast do elementary particles wobble? A surprising answer to this seemingly inconsequential question came out of Brookhaven National Laboratory in New York, USA in 2001, and indicated...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Tuesday, April 13, 2021 2:49:21 pm CDT
Julian Date:2459318.32594
Local Sidereal Time:02:52:24.6

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. Earth Gains 5,200 Tons of Dust From Space Every Year (Tue Apr 13 10:45 am)
    Whenever I wipe the dust off my coffee table or catch a glimpse of dust motes floating in sunlight, my spacey mind always wonders, is any of that cosmic dust? It just might be. But the amount of space dust that lands on our planet every year...
  2. The Same Technology Could Search for Microbes in Mars Rocks or Under the ice on Europa (Mon Apr 12 9:08 pm)
    NASA's SHERLOC and WATSON, two spectrometers designed to look for biosignatures, could answer if there's life on Mars on inside the Solar System's icy moons. The post The Same Technology Could Search for Microbes in Mars Rocks or Under the...
  3. Trojan Mission Lucy Tested its Solar Panels for the First Time. Those Things are Huge (Mon Apr 12 7:37 pm)
    Space missions often have to go where the sun don't shine. Or at least where it shines very faintly.  That is particularly important if the mission draws its power from the sun.  Luckily, engineers have a way of dealing with that problem...
  4. Gaia Finds 12 Examples of Einstein Crosses; Galaxies Being Gravitationally Lensed so we see Them Repeated 4 Times (Mon Apr 12 11:46 am)
    After examining data from the Gaia Observatory, a team of researchers found 12 more examples of the rare phenomenon known as "Einstein Crosses." The post Gaia Finds 12 Examples of Einstein Crosses; Galaxies Being Gravitationally Lensed so we...
  5. Brown Dwarfs can Spin so Fast They Almost Tear Themselves Apart (Mon Apr 12 10:34 am)
    Some brown dwarfs rotate so fast that they are flattened spheres. If they rotate any faster they might fly apart. The post Brown Dwarfs can Spin so Fast They Almost Tear Themselves Apart appeared first on Universe Today.

  1. Study warns of 'oxygen false positives' in search for signs of life on other planets (Mon Apr 12 11:00 pm)
    (University of California - Santa Cruz) In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however,...
  2. UMass Lowell celebrates the discoveries driving COVID-19, Mars research in free program series (Mon Apr 12 11:00 pm)
    (University of Massachusetts Lowell) UMass Lowell experts on the COVID-19 virus, NASA's research on Mars and efforts to bring a more diverse workforce to science-related fields will share their insights on these topics as part of a free event...
  3. Novel theory addresses centuries-old physics problem (Mon Apr 12 11:00 pm)
    (The Hebrew University of Jerusalem) The new study focuses on the outgoing flux of phase-volume, rather than the phase-volume itself. Since the flux is finite even when the volume is infinite, this flux-based approach avoids the artificial...
  4. Skoltech studies collective behavior of nanosatellites (Mon Apr 12 11:00 pm)
    (Skolkovo Institute of Science and Technology (Skoltech)) Scientists from the Skoltech Space Center (SSC) have developed nanosatellite interaction algorithms for scientific measurements using a tetrahedral orbital formation of CubeSats that...
  5. Physicists will print magnets with a 3D printer (Mon Apr 12 11:00 pm)
    (Ural Federal University) Physicists will print unique small magnets, magnetic systems, soft magnetic elements with a 3D printer. Samples made with this printer can be useful in almost any field from medicine to space.
