Latest Galaxies Stories
UCSB astrophysicist uses data gathered by a Russian spacecraft to bring science one step closer to figuring out the mysteries of our galaxy’s core.
Approximately 12 million light years from Earth is a galaxy called NGC 7793, and just on the outskirts of this galaxy is a black hole, designated P13, which new research has revealed is ingesting a weight equivalent to 100 billion billion hot dogs every minute.
Certain primordial stars—those between 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
Astronomers have discovered a supermassive black hole in the ultracompact dwarf galaxy M60-UCD1, making it the smallest galaxy ever found to host one of these enormous light-sucking objects.
New observations explain why Milky Way-like galaxies are so common in the Universe
New work from Carnegie’s Hubble Fellow Yue Shen and Luis Ho of the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University solves a quasar mystery that astronomers have been puzzling over for 20 years.
Astronomers from the University of Maryland and NASA’s Goddard Space Flight Center in Greenbelt, Maryland have accurately measured and confirmed the existence of a black hole roughly 400 times the mass of our sun.
University of Maryland and NASA astronomers used rhythmic flares of light to measure a brilliant object 12 million light years from Earth, confirming that it is a rare, mysterious intermediate-mass black hole.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
