When a star comes too close to a black hole, the intense gravity of the black hole results in tidal forces that can rip the star apart.

Astronomers have discovered a previously unknown link between the way young stars grow and the way black holes and other exotic space objects feed from their surroundings.

Astronomers using NASA's Hubble Space Telescope have found that Markarian 231 (Mrk 231), the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously whirling about each other.

Astronomers using NASA's Chandra X-ray Observatory and the 6.5-meter Clay Telescope in Chile have identified the smallest supermassive black hole ever detected in the center of a galaxy.

A super-dense star formed in the aftermath of a supernova explosion is shooting out powerful jets of material into space, research suggests.

Five billion years ago, a great disturbance rocked a region near the monster black hole at the center of galaxy 3C 279.

A NASA satellite controlled by Penn State University has detected a brief, super-bright, high-energy flare -- an X-ray nova -- erupting from a star system 8,000 light-years away from Earth named V404 Cygni.

At the time, the astronomers also looked back at archival data from optical telescopes over the twentieth century, finding two previous outbursts, one in 1938 and another one in 1956.

Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun.

In 2013, astronomers announced they had discovered a magnetar exceptionally close to the supermassive black hole at the center of the Milky Way using a suite of space-borne telescopes including NASA's Chandra X-ray Observatory.

Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy.

Shred a document, and you can piece it back together. Burn a book, and you could theoretically do the same. But send information into a black hole, and it's lost forever.

A supermassive black hole with a mass four million times that of the Sun lies at the heart of the Milky Way galaxy.

By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce "wind" produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across.

Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time.

NASA's NuSTAR and ESA's XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions -- a phenomenon that had been suspected, but difficult to prove until now.

The team responsible for the Oscar-nominated visual effects at the center of Christopher Nolan's epic, Interstellar, have turned science fiction into science fact by providing new insights into the powerful effects of black holes.

A new high-energy X-ray image from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has pinpointed the true monster of a galactic mashup. The image shows two colliding galaxies, collectively called Arp 299, located 134 million light-years away. Each of the galaxies has a supermassive black hole at its heart.

High-energy jets powered by supermassive black holes can blast away a galaxy's star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones.

An international group of researchers with the participation of the Astronomic Observatory of the Universitat de València has discovered the first lightning bolts from a black hole by eruption with the strongest brightness variations in an extragalactic object ever observed.
