Universe Today 11 Mar 2021, 13:48 UTC Sometimes the sun spits out high-energy particles which slam into the Earth, potentially disrupting our sensitive electronics. New research has found that these particles originate in the plasma of the sun itself, and are trapped there by strong magnetic fields.
Universe Today 10 Mar 2021, 22:00 UTC Supermassive black holes are just a little bit too supermassive – astronomers have difficulty explaining how they got so big so quickly in the early universe. So maybe it’s time for a new idea: perhaps giant black holes formed directly from dark matter.
Scientific American 10 Mar 2021, 13:00 UTC The work of decoding the cosmic traveler has surprising relevance right now.
Universe Today 10 Mar 2021, 01:30 UTC It sounds like science fiction, but building an enormous tower several kilometers high on the Lunar surface may be the best way to harness solar energy for long-term Lunar exploration. Such towers would raise solar panels above obstructing geological features on the Lunar surface, and expand the surface area available for power generation.
Sky and Telescope 9 Mar 2021, 18:42 UTC Alnilam is the middle star in the famous three-member belt of Orion, the Hunter. The belt is so easily recognizable because all three stars are spaced evenly in a (roughly) straight line and appear to be about the same brightness. But Alnilam stands out for being super massive, super distant, and, perhaps most intriguingly, super luminous.
Universe Today 9 Mar 2021, 13:08 UTC Neutrinos are notoriously finicky particles. Hundreds of trillions pass through a person’s body every second, yet they hardly seem to interact with anything (though they actually do a lot). Even more hard to find are the “high energy” neutrinos that are believed to be formed as the outcome of some of the most violent events in the universe. Now, researchers using NASA’s Swift telescope have found a high energy neutrino for the first time from one type of those ultra-violent events – a tidal disruption. But something was a little bit off about it.
New Scientist 9 Mar 2021, 07:00 UTC A survey of more than 1 million galaxies across the cosmos has shown that the distribution of matter may not be the same in every direction, which could upend much of what we understand about the universe.
Universe Today 8 Mar 2021, 16:52 UTC The University of Colorado Boulder and Lunar Resources Inc. have just won NASA funding to study the possibility of building a radio telescope on the far side of the Moon. The project, called FarView, would allow radio astronomers to observe the sky in low-frequency radio wavelengths with unprecedented clarity.
