Wonderful!! 83 supermassive black holes found in the early universe

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the sun. While they...
This artist's impression shows hot gas orbiting in a disk around a rapidly-spinning black hole. The elongated spot depicts an X-ray-bright region in the disk, which allows the spin of the black hole to be estimated. Image: NASA/CXC/M. Weiss

X-ray pulse detected near event horizon as black hole devours star

On Nov. 22, 2014, stargazers detected an uncommon vent in the night sky: A supermassive black hole at the center of a galaxy, almost...

Scientists uncover new properties of black holes

The National Science Foundation’s LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational wave detectors have detected gravitational waves from a total of 10...
Two images of Cygnus A layered over each other to show the galaxy’s jets glowing with radio radiation (shown in red). Quiescent galaxies, like our own Milky Way, do not have jets like this, which may be related to magnetic fields. The yellow image shows background stars and the center of the galaxy shrouded in dust when observed with visible light. The area SOFIA observed is inside the small red dot in the center.

Magnetic fields may be the key to black hole activity

Black holes are objects so dense, and with so much mass, that even light cannot escape their gravity. However, astronomers can study the effects...

New simulation sheds light on spiraling Supermassive black holes

Another model is conveying researchers a bit nearer to understanding the sorts of light signals created when two supermassive black holes, which are millions...
This artist's impression shows a binary system containing a stellar-mass black hole called IGR J17091-3624, or IGR J17091 for short. The strong gravity of the black hole, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black hole, and the wind is driven off this disk. Credit: NASA/CXC/M.Weiss

Another way for stellar-mass black holes to grow larger

Scientists at the University of Hong Kong and Academia Sinica Institute of Astronomy and Astrophysics in Taiwan and Northwestern University in the U.S. come...

Finding the happy medium of black holes

Using data from NASA's Chandra X-ray Observatory and other telescopes, scientists have taken major steps in their hunt to find black holes. Through this...
An artist’s impression shows the atmosphere of a Neptune-like planet (foreground) being swept backward by powerful radiation from an outburst in the center of the Milky Way (right). The planet’s host star is shown on the left

Black hole blasts may transform ‘mini-Neptunes’ into rocky worlds

According to the team of astronomers at the Harvard Gazette center of the Milky Way were changed into rocky planets by outbursts created by the...
