Some black holes may be gravastars with tiny universes inside, new study says

June 19, 2026 10:06 am

Black holes and gravastars take centre stage in a new study that proposes an alternative fate for collapsing massive stars.

As black holes consume gas and dust, the heat emits radiation that pushes gas and other materials, creating wind. When the cosmic munching of the black hole is extensive, the winds can be so powerful that materials can be cleared out of the galaxy.

What caused early supermassive black holes? Study points to dark matter decay

April 29, 2026 8:46 am

New research suggests decaying dark matter may be the "secret ingredient" behind the early existence of supermassive black holes discovered by the James Webb Space Telescope, challenging a billion years of cosmic theory.

The Big Bang’s 'missing' half: Why new research suggests black holes swallowed the universe’s antimatter

March 26, 2026 8:52 am

A new theory suggests primordial black holes may explain why matter dominates the cosmos.

From 'failed supernovae' to supermassive monsters, black holes reveal what happens when gravity overwhelms everything else.

Giants, ghosts, and gravity traps: The many lives of black holes

Black holes are not cosmic vacuum cleaners. They are among the universe’s most extreme objects - and come in different sizes.

In general, a black hole is a region in Space where the pulling force of gravity is so strong that neither matter nor light can ever escape.

Why merger of two black holes, 100 times bigger than the Sun, holds significance

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

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.

On May 20, the full-scale Engineering Development Unit Telescope for the LISA (Laser Interferometer Space Antenna) mission, still in its shipping frame, was moved within a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, US.
