Scientists ponder over discovery of 'physically impossible' black hole

Scientists are analysing the gravitational-wave signals provided by LIGO and Virgo interferometer that provide details of a giant black hole which is so huge that until now has been thought to be physically impossible. So far, they have refused to confirm or deny the detection.

Scientists spotted a black hole swallowing a neutron star

A black hole swallowing a neutron star has been identified for the first time, according to space scientists.


Supermassive black hole in our galaxy's centre suddenly turned 75 times brighter

Sagittarius A* (Sgr A*) a supermassive black hole at the heart of the Milky Way, suddenly glowed way too brighter than its normal state becoming 75 times more luminescent before going back to its normal state earlier this year.

Scientists have found the only star that escaped a supermassive black hole

Scientists have traced the star named S5-HVS1 which ejected out of the supermassive black hole Sagittarius A* (Sgr A*) and has been moving at a massive speed of 1,700 kilometers per second since then.

Plasma-spewing black hole dragging spacetime

Like many black holes, it is feeding on a nearby star, pulling gas away from the star and forming a disk of material that encircles the black hole and spirals towards it under gravity.

Black Hole: From where no light can escape

The more massive a body, the bigger and deeper the size of the curvature it creates in space-time. Consequently, the higher is the escape velocity required to pull away from its gravity.


What black hole image tells us

When scientists ‘photographed’ an invisible black hole: the image captures the area around it, generated from data collected by a set of telescopes, and provides a platform for understanding black holes better.

A science teacher explains: What is a Black Hole and some fun facts for kids

Black Hole facts: When a particle draws too close to a black hole and the source of the powerful gravitational field, it is stretched into long thin shapes, like pasta. The term spaghettification was coined by Stephen Hawking in his book, A Brief History of Time.

First supermassive black hole photographed to be named Powehi

The team of astronomers who created the image of the black hole called it M87(asterisk). (The asterisk is silent.) A language professor has given it a name from a Hawaiian chant — Powehi.

First black hole image: Here are five things that we learnt

Space scientists unveiled the first-ever photograph of a black hole taken from the Event Horizon Telescope (EHT) project earlier this week. The photograph shows the black hole that is located at Messier 87 (M87) galaxy, which is some 55 million light-years away from here.
