Black Hole X Ray Mystery Solved
2013-06-14 14:00:15

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.

Black Hole Count Keeps Growing For The Andromeda Galaxy
2013-06-13 06:10:47

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.

NuSTAR Observes Dormant Black Hole In Nearby Sculptor Galaxy
2013-06-12 08:35:23

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.

Galaxy Mega Merger Spotted By Herschel And Keck
2013-05-23 04:53:50

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.

Sagittarius A Black Hole To Devour 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.

Distant Black Hole Wakes Up For A Snack
2013-04-02 13:51:29

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.

The Milky Way's Violent Past
2013-03-06 04:20:09

As astronomers peer out into the distant reaches of the Universe they find that some galaxies are emitting enormous amounts of radiation from their cores.

NASA X-Ray Observatories Reveal Black Hole Spin
2013-02-27 17:22:50

Scientists affiliated with NASA’s NuSTAR and XMM-Newton X-ray observatories have now devised a clever way to directly measure the rotation of nearby supermassive black holes.

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...
