During the last few hundred years, the dim region very close to the supermassive black hole near the center of the Milky Way flared up with at least two luminous outbursts, according to a team of researchers using NASA's Chandra X-ray Observatory.

Colliding Galaxies Create Supermassive Black Holes

At the center of almost every galaxy we have studied is a black hole of such magnitude that the traditional black hole progenitor does not seem likely. These aptly named supermassive black holes can reach millions or billions of times the mass of our Sun.

Virtual Observatory Study Explains How Black Holes Get So Massive

New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in the high-altitude Atacama Desert of Chile have revealed new details about the powerful molecular-gas jets that stream out of supermassive black holes.

Sleeping Supermassive Black Holes Can Have Periods Of Intense Flare-Ups

Around 2 million years ago, the supermassive black hole at the center of our galaxy erupted in a blaze of glory big enough to leave a residual glow that can still be seen today.

Black Hole Blows Powerful Streams

A worldwide network of radio telescopes has allowed astronomers to find strong evidence that a powerful jet of material is blowing massive amounts of gas out of the host galaxy.

Black Holes Shine For NuSTAR
2013-09-06 06:38:46

The Nuclear Spectroscopic Telescope Array spacecraft, NASA’s black-hole-hunter, had identified its first 10 supermassive black holes.

Researchers Explain Why Supermassive Black Holes Eat Less Material Than Expected
2013-08-30 08:51:11

A long-standing mystery concerning super massive black holes at the center of galaxies has been solved by a team of astronomers using NASA’s super-sensitive Chandra X-ray space telescope.

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...
