Astronomers Catch Supermassive Black Hole Devouring Distant ...

Astronomers have for the very first time captured a supermassive black hole devouring a wandering star that strayed too close to a phenomena that nothing can escape, not even light. Although the star most likely met its demise in an un [...]

Astronomers put forward new theory on size of black holes

Astronomers have put forward a new theory about why black holes become so hugely massive – claiming some of them have no 'table manners', and tip their 'food' directly into their mouths, eating more than one course s [...]

Astronomers aim to take first picture of black hole

Taking a picture of a black hole, an object so gravitationally bound that not even photons of light can escape, sounds like an oxymoron, but astronomers this week will attempt to do just that. What they're hoping to glimpse is somethi [...]

Astronomers determine full description of a black hole

They say that nothing can escape a black hole, but a complete description of the basic structure of these dense masses has escaped a black hole’s clutches, enabling a team of astronomers to characterise one of them, Cygnus X-1, for [...]

Chandra adds to black hole birth announcement

Over three decades ago, Stephen Hawking placed -- and eventually lost - a bet against the existence of a black hole in Cygnus X-1. Today, astronomers are confident the Cygnus X-1 system contains a black hole. In fact, a team of scientists [...]

Mini black hole packs powerful punch

Using ESO's Very Large Telescope to follow up on a NASA Chandra X-ray telescope observation, the most powerful pair of jets ever seen have been found bursting from a black hole of just a few solar masses. This so-called microqua [...]

Black Holes Gain Weight And Light Up during Galaxy Collision...

Giant black holes in the centers of galaxies grow mainly as a result of intergalactic collisions, according to results presented by a group of astronomers led by Dr. Ezequiel Treister from the University of Hawaii, published in the March [...]

UA astronomer discovers unusual black hole activity

Today, astronomers around the world are making new discoveries studying the vastness of space. One such astronomer teaching at the University of Alabama has made major progress in studying black holes and has documented for the first tim [...]

Black holes may act like cosmic factories for building galax...

Astronomers have long wanted an answer to the chicken-and-egg question of what comes first, a super-massive black hole or the galaxy of stars surrounding it? A new observation of a 'quasar' five billion light years from Earth may now help t [...]

Astronomy team probes edge of supermassive black hole

A supermassive black hole lurking deep in the heart of a distant active galaxy has been probed more closely than ever before by a team of astronomers that includes Penn State Professor of Astronomy Niel Brandt. Using new X-ray data from th [...]

Elusive Binary Black Hole System Identified

Finding a needle in a haystack might be easy compared to finding two very similar black holes closely orbiting each other in a distant galaxy. Astronomers from the National Optical Astronomy Observatory (NOAO) in Tucson, Arizona, have foun [...]

Astronomers spot dancing black hole twins

U.S. astronomers reported on Wednesday that they have spotted a pair of super massive black holes orbiting each other within the same galaxy.This is the best evidence so far for the long-theorized existence of "binary black hole system [...]

Supermassive Black Hole Kicked Out of Galaxy: First Ever Obs...

April 30, 2008 - For the first time, the most extreme collision to occur in the cosmos has been observed. Galaxies are known to hide supermassive black holes in their cores, and should the galaxies collide, tidal forces will cause massive d [...]

M33 X7 SuperMassive Black Hole

The main component of this graphic is an artist's representation of M33 X-7, a binary system in the nearby galaxy M33. In this system, a star about 70 times more massive than the Sun (large blue object) is revolving around a black hole.Th [...]
