Latest Supermassive black hole Stories
Brett Smith for redOrbit.com - Your Universe Online Astrophysicists have suspected that desolate “red and dead” galaxies are only formed by powerful supermassive black holes at the center of these galaxies stripping away all of the essential star-forming gas from a stellar nursery. However, a new study in The Astrophysical Journal has revealed that less powerful black holes are capable of creating dead galaxies full of red giant stars by generating a “perfect storm” of...
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.
New observations of the Perseus and Virgo galaxy clusters suggest that turbulence may be the reason that hot gas there has been unable to cool, providing a possible answer to a long-standing question as to why these galaxy clusters never seem to form large numbers of stars.
The same phenomenon that causes a bumpy airplane ride, turbulence, may be the solution to a long-standing mystery about stars' birth, or the absence of it, according to a new study using data from NASA's Chandra X-ray Observatory.
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.
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.
An extreme and rare event in the region of space immediately surrounding a supermassive black hole has been captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR.
New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way.
Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...
Black Hole -- Black holes are objects so dense that not even light can escape their gravity. They are believed to form from the gravitational collapse of astronomical objects containing two or more solar masses. Astronomical observations suggest that the center of most galaxies, including our own Milky Way, contain supermassive black holes containing millions to billions of solar masses. Black holes are predictions of Einstein's theory of general relativity. In particular, they occur...
