Latest Supermassive black hole Stories
An international team of astronomers was able to measure the radius of a black hole for the first time.
The center of the Milky Way seems like the last place to form a new planet, inhospitable and violent even. Stars crowd each other, whizzing through space like cars on a rush hour freeway while supernova explosions blast out shock waves and bathe the region in intense radiation.
Millions of black holes have been discovered, as well as extreme galaxies called hot DOGs using NASA's Wide-field Infrared Survey Explorer mission.
Fueled by an intense burst of star formation, fierce galactic winds may blow gas right out of massive galaxies, which in turn could shut down their ability to make new stars.
Astronomers now believe the "monster stars" located in the nearby galaxy the Large Magellanic Cloud (LMC) were formed through the merger of lighter stars.
Astronomers have identified an X-ray signal that followed an observation made last year of a quiescent black hole in a distant galaxy. The black hole discovered by the team last year was seen erupting after shredding and consuming a passing star.
Gamma-ray beams seen in the Milky Way's central black hole suggest that the galaxy's center was much more active in the past, according to new research.
By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away.
The strange galaxy Centaurus A is pictured in a new image from the European Southern Observatory (ESO). With a total exposure time of more than 50 hours this is probably the deepest view of this peculiar and spectacular object ever created.
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...
