  • Astronomers discover new ‘fossil galaxy’ buried deep within the Milky Way

    Source: Phys.org Scientists working with data from the Sloan Digital Sky Surveys’ Apache Point Observatory Galactic Evolution Experiment (APOGEE) have discovered a “fossil galaxy” hidden in the depths of our own Milky Way. This result, published today in Monthly Notices of the Royal Astronomical Society, may shake up our understanding of how the Milky Way

  • New Study Expands Breakthrough Listen Initiative’s Search for Intelligent Life

    In a new study to be published in the Monthly Notices of the Royal Astronomical Society, a research team led by University of Manchester astronomers extended a sample of 1,327 stellar systems recently observed by the Breakthrough Listen Initiative by including additional 288,315 stars that also reside within the target fields of the Robert C. Byrd Green Bank Telescope in West Virginia and CSIRO’s Parkes radio telescope in Australia — increasing the number of stars analyzed by a factor of more than 200. Their results suggest that less than 0.04% of stellar systems have the potential of hosting advanced civilizations with the equivalent or slightly more advanced radio technology than 21st century humans.

  • NASA’s Chandra X-ray Observatory Watches Fast Blast Wave from Exploded Star

    A stellar structure known as the ‘Hand of God’ is a nebula of energy and particles blown by a pulsar left behind after a star exploded in our Milky Way Galaxy. Otherwise known as MSH 15-52 or G320.4-1.2, the object is located some 17,000 light-years away in the constellation of Circinus. Astronomers estimate that light from the supernova explosion reached Earth about 1,700 years ago, or when the Mayan empire was flourishing and the Jin dynasty ruled China. Previously, astronomers had released a full view of the structure. In a paper in the Astrophysical Journal Letters, they report how quickly the supernova remnant associated with the hand is moving, as it strikes a cloud of gas called RCW 89; the inner edge of this cloud forms a gas wall located about 35 light-years from the center of the explosion.
