Astronomers Spot Hundreds of Hidden Supermassive Black Holes Using Infrared
Hundreds of hidden supermassive black holes have been identified using infrared observations, offering fresh insights into their role in galaxy formation. Researchers relied on data from NASA's Infrared Astronomical Satellite (IRAS) and the Nuclear Spectroscopic Telescope Array (NuSTAR) to detect emissions from black holes obscured by thick clouds ...

Astronomers Observe Black Hole Reactivate, Emitting Jets of Plasma
A supermassive black hole at the center of galaxy 1ES 1927+654 has been observed reactivating after a quiet period. Jets of hot gas were released from both sides of the black hole, surprising astronomers. Researchers speculate that a white dwarf star in close orbit may be interacting with the black hole, providing key insights into cosmic behavior....

Hidden Supermassive Black Holes Found Behind Gas and Dust Across the Universe
Supermassive black holes, which feed on surrounding material, may be more common than earlier believed. Researchers suggest that nearly 30%-50% of these black holes could be concealed behind dense gas and dust, making them invisible to standard telescopes. The study, based on infrared observations, sheds light on how these entities influence star f...

Supermassive Black Hole Flashed Twice in a Rare Event, Scientists Explain the Reason
In a galaxy 408 million light-years away, the black hole ASASSN-22ci consumed a star from a binary system, producing a rare double-flash tidal disruption event (TDE). First observed in February 2022, a second flare occurred 720 days later, possibly caused by Hills capture. Researchers anticipate a third flare in early 2026, offering unprecedented i...

A World-First Discovery - Twin Stars Trapped Orbiting Galactic Black Hole
At the centre of the Milky Way is a supermassive black hole called Sagittarius A*. It is roughly 27,000 light years from Earth and 23.5 million kilometres in diameter.

Binary Star System D9 Found Orbiting Sagittarius A* Near Milky Way’s Core
Astronomers have detected a young binary star system, D9, orbiting Sagittarius A*, the supermassive black hole at the Milky Way's centre. This challenges previous assumptions about star survival near intense gravitational forces. The discovery was made using the European Southern Observatory's Very Large Telescope. Future research with advanced tel...

Hubble Captures NGC 5643’s Spiral Arms, Star Formation, and Hidden Black Hole
The NASA/ESA Hubble Space Telescope has captured detailed images of the spiral galaxy NGC 5643, located 40 million light-years away. This grand design galaxy features striking spiral arms outlined by young blue stars and dust clouds, with star-forming regions visible as pinkish hues. Ultraviolet and X-ray studies have revealed an active galactic nu...

James Webb Space Telescope Reveals Unique Features of Westerlund 1 Star Cluster
The James Webb Space Telescope has captured groundbreaking images of Westerlund 1, a supermassive star cluster located 12,000 light-years away. The new findings offer a closer look at star formation processes, particularly the discovery of brown dwarfs, and highlight the role of energetic radiation in shaping planetary environments.

Two Black Holes With Unusual Behaviour Disrupt Traditional Theories About Their Formation
Astronomers are observing two unique black holes defying established cosmic theories. One, known as the "serial killer" black hole, is preparing to consume its second star in five years, an event that rarely occurs within such a timeframe. The other black hole, part of a triple system called V404 Cygni, has a structure that defies traditional black...

Supermassive Black Hole at the Centre of the Milky Way Is Spinning Unexpectedly
Sagittarius A* (pronounced Sagittarius A Star), the supermassive black hole at the centre of the Milky Way, is spinning in an unusual way, and scientists now believe they may know why. Based on new data from the Event Horizon Telescope, researchers suggest that this cosmic giant likely merged with another black hole billions of years ago. This colo...

Supermassive Black Holes Might Be Responsible for the Death of a Galaxy, Says Study
Supermassive black holes might be influencing galactic star formation and triggering the death of galaxies, claims a new stuy. Recent research has shed light on how the birth and death of a galaxy, also known as galactic cycle occurs. This study reveals that the mass of a supermassive black hole can significantly impact the amount of cold gas avail...

Scientists Discover Oldest Black Hole Ever That's 'Eating' Its Host Galaxy
Scientists said it is surprising to know that such supermassive black hole, which is a few million times the mass of our Sun, existed in the early universe.

Supermassive Black Hole Spotted Eating Sun-Like Star in Nearby Galaxy
Black holes, celestial objects known for their gluttony, usually eat stars unlucky enough to stray too close to them in one big gulp, annihilating them with their enormous gravitational pull. But some, it turns out, tend to snack rather than gorge. Researchers said they have observed a supermassive black hole at the center of a relatively nearby ga...

James Webb Telescope Finds Evidence Of ''Celestial Monster'' Stars The Size of 10,000 Suns
These ''celestial monsters'' are 5000 to 10000 times more massive and five times hotter at their centre than the Sun.

NASA's Hubble Telescope Spots Runaway Supermassive Black Hole Leaving Behind Trail of Newborn Stars
A supermassive black hole, weighing as much as 20 million Suns, has left behind a 2,00,000-light-year-long condensed trail of newborn stars, twice the diameter of the Milky Way galaxy, in its wake, according to the National Aeronautics and Space Administration (NASA), US. Captured accidentally by NASA's Hubble Space Telescope, the black hole was se...
