Thanksgiving Dinner At The Center Of The Galaxy
2012-11-22 10:33:45

NASA's NuSTAR spacecraft has detected the Milky Way's central black hole eating a Thanksgiving snack. Supermassive black holes like the one in the middle of our galaxy sustain themselves by swallowing stars, planets, asteroids, comets and clouds of gas that wander around the galaxy.

Bright Flare In A Black Hole

NASA's Chandra X-ray Observatory has identified one of the lowest mass supermassive black holes ever observed in the middle of a galaxy that one would not expect to harbor this type of beast.

NuSTAR Picks Up First Black Hole X-ray Flare Up

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted its first flare from Milky Way's black hole.

Black Hole Afterburner Moves At The Speed Of Light

A supersonic jet of material that looks amazingly similar to the afterburner flow of a fighter jet is blasting over two million light-years from the center of a distant galaxy.

Milky Way Black Hole Ready For A Snack

Scientists have determined that the black hole in the middle of the Milky Way is getting ready to devour an approaching cloud of dust and gas.

Early Universe Was Full Of Supermassive Black Holes
2012-10-08 12:41:21

Scientists have discovered a new population of supermassive black holes in the early universe by using infrared surveys.

Star Discovery Tests Einstein

Astronomers, using the Keck Observatory, have found the star they need to test Einstein's theory about the fabric of space-time.

Messier 22 Has Two Black Holes
2012-10-03 12:49:09

A surprising black hole discovery made while using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) is causing scientists to change what they know of globular star clusters.

Astronomers Describe Fireworks In The Early Universe
2012-09-27 19:28:13

Astronomers suggest, in the Astrophysical Journal Letters, as galaxies formed in the early universe, they were accompanied by fireworks in the form of energy bursts.

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...

Seyfert Galaxy -- Seyfert galaxies are spiral or irregular galaxies containing an extremely bright nucleus, most likely caused by a supermassive black hole, that can sometimes outshine the surrounding galaxy. The light from the central nucleus varies in less than a year, which implies that the emitting region must be less than one light year across. They are named for the astronomer Carl Seyfert, who studied them extensively in the 1940s. They are a subclass of active galactic nuclei....

Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
