Using the Large High Altitude Air Shower Observatory (LHAASO), astronomers have performed a search for new high-energy gamma-ray sources. As a result, they have identified a new ultra-high energy gamma-ray source, which received ...
MIT astronomers have discovered new and unusual galactic neighborhoods that previous studies overlooked. Their results, published today, suggest that roughly 1 percent of galaxy clusters look atypical and can be easily misidentified ...
