Why merger of two black holes, 100 times bigger than the Sun, holds significance
July 18, 2025 12:51 pm
The detection of gravitational waves from this event has generated a lot of scientific interest. It has the potential to refine the current understanding of black hole formation, the evolution of stars, and, possibly, the current models of the universe itself.
New research shows Vaidya Radiation may enable Hawking radiation in black holes
November 06, 2024 11:02 am
In a statement issued on Tuesday by IUCAA, the researchers said that "Hawking radiation is a well-known concept in Astrophysics, but something critical is required for it to come out so that a Black Hole can always remain 'black'.
First ‘black hole triple’ system discovered: What does it mean?
November 01, 2024 11:02 pm
The discovery of the system, located about 8,000 light years away from Earth (one light year is the distance light travels in a year, 9.5 trillion kilometre), has raised questions about how black holes are formed.

'If we find evidence that black holes transform into white holes...it would mean that spacetime can also make quantum jumps': Carlo Rovelli
November 23, 2023 7:55 am
The Italian theoretical physicist on how white holes can upend our understanding of the structure of the universe, his new book that traces the ongoing research into their potential and why he is unimpressed with AI
Watch this space: Two galaxies walk into a bar and the oldest black hole ever discovered
November 13, 2023 8:12 am
Galactic bars are believed to form in spiral galaxies where stars rotate in an ordered fashion, like the Milky Way. In such a galaxy, a bar can form almost spontaneously because of instabilities in the spiral structure or the effect of gravity from a nearby galaxy.
The universe's hum and an opportunity to explore
July 07, 2023 10:07 pm
Whatever the ultimate origin of what is being called the “hum” of the universe by the press, it is clear that these nanohertz waves would, in future, allow us to explore the earliest universe

July 01, 2023 7:20 am
The sheer scale of space-time revealed in the 'background hum of the universe' can cause existential dread
Runaway black hole rockets through space, leaving behind trail of newborn stars
April 12, 2023 12:16 pm
The black hole is as heavy as 20 million Suns and is also leaving behind a 200,000-light-year-long trail of newborn stars.
