Scientists Predict Ultramassive Black Holes Can’t Grow Beyond 100 Billion Suns
Scientists led by Dr Priyamvada Natarajan from Yale University have discovered that ultramassive black holes likely cannot exceed 100 billion solar masses. These giants regulate their own growth by emitting gas jets that heat and expel surrounding material, cutting off their gas supply. Additionally, the team is exploring intermediate-mass black ho...

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...

NASA James Webb Space Telescope Unearths Oversupply of UV Light from Early Stars and Black Holes
NASA’s James Webb Space Telescope (JWST) has revealed surprising new details about the universe's reionization process. The telescope has found an unexpected oversupply of ultraviolet (UV) light emitted by early stars and giant black holes, contradicting previous theories. This discovery suggests a more complex reionization process, potentially d...

See These Iconic Images of Dust Filled Disks of Galaxies Captured by Hubble
NASA's Hubble Instagram page shared iconic Hubble images that captured disks of dust fuelling black holes at the centres of galaxies. The first image showed a giant disk of cold gas dust fuelling a black hole at the centre of an elliptical galaxy, named NGC 4261.

Giant Black Hole Discovered At Centre Of Cosmic "Spider's Web"
Astronomers have discovered six galaxies ensnared in the cosmic "spider's web" of a supermassive black hole soon after the Big Bang, according to research published Thursday that could help explain the development of these enigmatic monsters.

NASA Spots Biggest Explosion Seen in the Universe, Caused by Supermassive Black Hole. Pune Telescope Helped
The discovery was made by NASA scientists using X-ray data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton, coupled with radio data sourced from Murchison Widefield Array (MWA) in Australia and India's Giant Metrewave Radio Telescope (GMRT).

Cosmic Explosions Even More Powerful Than First Thought: Study
The biggest explosions since the Big Bang set the universe in motion some 13 billion years ago produced even more energy than first thought, scientists said Wednesday.

3 Giant Black Holes On The Path To Collision, Captured In Rare Discovery
Three galaxies are on the course to collision, along with the giant black holes at the centre of each of them, a new study found. This has been spotted by astronomers at NASA for the first time

Supernova Remnants Found in Antarctic Could Be 20 Million Years Old
A star collapses when it dies, spewing space dust in a giant cloud of elements that make for very beautiful Hubble Telescope photos.

Supernova Dust Found In Antarctic Could Be 20 Million Years Old
A star collapses when it dies, spewing space dust in a giant cloud of elements that make for very beautiful Hubble Telescope photos. The "explosion," called a supernova, results in either a black hole or a small, dense star that no longer generates heat.

Sonia Gandhi On Difference Between PM Modi and Atal Bihari Vajpayee
Congress leader Sonia Gandhi confessed that she "knew her limitations" as a leader and was not a natural at public speaking, in a candid speech at the India Today conclave today.

First Image of Black Hole Pieced Together by Astronomers
"Instead of building a telescope so big that it would probably collapse under its own weight, we combined eight observatories like the pieces of a giant mirror."

Powerful 'Cosmic Double Whammy' Discovered
Astronomers have discovered a supermassive black hole and the collision of giant galaxy clusters about two billion light years from Earth.

'Brightest Supernova' Result Of Giant Black Hole Destroying Star
An intense flare detected last year in a distant galaxy about four billion light years from Earth, considered to be the brightest supernova ever observed, is actually a tidal disruption event (TDE) -- the destruction of a star by a rapidly spinning super massive black hole, suggests new research.

Can Two Huge 'Black Holes' On Sun Put Us In Trouble?
We imagine the Sun as a giant burning furnace that brings sunlight to us but NASA's Solar Dynamics Observatory (SDO) has spotted two huge holes on its surface called "coronal holes".
