Twin Black Holes Spotted Feasting On Cosmic Materials
At the centre of two merging galaxies, two black holes have been observed devouring matter side by side, raising the possibility that binary black holes are more frequent than previously assumed.

Researchers Predict Imminent Collision Between 2 Supermassive Black Holes
Astronomers from Guangzhou University in China have used data from a range of X-ray observatories while covering a time period of 200 days. They tried to identify the high-energy signatures that are expected to be detected in a close supermassive black hole binary or a decaying orbit.

Dormant Black Hole Deemed ‘Needle in a Haystack’ Identified Outside the Milky Way
Astronomers have identified a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star, in a galaxy adjacent to the Milky Way. Black holes are extraordinarily dense objects with gravity so intense not even light can escape. Deemed a cosmic "needle in a haystack", the newly discovered ‘d...

Eight New Echoing Black Hole Binaries Discovered in Our Galaxy: MIT Researchers
Black holes are intriguing and mysterious objects. They are dreaded, too, because their gravitational pull is so strong that they do not allow anything to pass through them, not even light, except on the rare occasions when they feed. When a black hole pulls in gas and dust from an orbiting star, it sends out spectacular bursts of X-ray that bounce...

Astrophysicists Detect Black Hole-Neutron Star Mergers For The First Time
Astrophysicists say that the newly observed phenomena will allow them to better understand the formation of binary star systems and how often they merge, something that has never been measured before.

AstroSat, Chandra X-Ray Observatory Find Black Hole That Spins Near Maximum Possible Rates
India's AstroSat and NASA's Chandra X-Ray Observatory have found that a black hole in the binary star system 4U 1630-47 spins close to the maximum possible rate.

Indian Satellite Helps Find Black Hole That Spins Near Max Possible Rate
Scientists using data from India's first dedicated astronomy satellite, AstroSat, and NASA's Chandra X-ray Observatory have found that a black hole in the binary star system 4U 1630-47 spins close to the maximum possible rate.
