In November, astronomers at the Max Planck Institute for Extraterrestrial Physics presented new observations of the gas cloud G2 in the galactic center originally discovered in 2011.
In his general theory of relativity, Albert Einstein predicted that there are such things as gravitational waves. In fact, the very existence of these waves is the linchpin of the entire theory.
Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way.
An unusual object located at the center of the Milky Way is most likely not a hydrogen gas cloud headed towards the galaxy’s black hole, but a pair of binary stars that had been orbiting it together before merging into a single, extremely large star.
Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale.
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.
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...
