Latest Galaxies Stories
Astronomers using a telescope attached to a modified Boeing 747SP aircraft have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way.
Observations of a nearby active galaxy using the Very Large Telescope Interferometer (VLTI) at ESO’s Paranal Observatory in Chile have shown astronomers something they hadn’t expected to see.
Astronomers from several institutions have used decades-worth of collected data to confirm theories about how stellar-mass black holes produce their highest-energy light known as hard X-rays.
Astronomers have discovered an unprecedented number of black holes in the Andromeda Galaxy (M31), one of the Milky Way’s nearest cosmic neighbors, using data from NASA’s Chandra X-ray Observatory.
NASA’s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor galaxy nearly a decade ago. A new observation by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep.
Around 11 billion years ago, two hungry young galaxies collided and they are now forming a massive galaxy approximately 10 times the size of the Milky Way. The new mega-galaxy, HXMM01, was discovered as part of a UC-Irvine led project conducted with the W.M. Keck Observatory, the Herschel space observatory, and other research facilities around the world.
The European Space Agency's (ESA) Herschel spacecraft has revealed that the supermassive black hole Sagittarius A at the center of our galaxy is about to get a taste of some hot molecular gas.
Despite the inhospitable nature of this region, a team of American astronomers has found jets of material that typically indicate star formation near a supermassive black hole.
Astronomers using the European Space Agency's (ESA) Integral space observatory have watched as a black hole woke up to feed on a low-mass object that strayed just a little too close.
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...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
