Webb telescope reveals rapid growth of primordial black hole

Black holes are extremely dense objects with gravity so strong that not even light can escape. With their immense gravitational pull, they grow in mass by sucking in material such as gas, dust and stars unfortunate enough to stray nearby.

Indian radio telescope at the heart of big black hole jet discovery

Critical cosmic signals picked up by the Giant Metrewave Radio Telescope at Khodad village near Pune have aided an international team of astronomers to spot the monstrous jets, whose length is equivalent to lining up 140 Milky Way galaxies back-to-back.

A new space mission may help physicists answer hairy questions about black holes

Since astrophysical objects such as stars and planets are known to spin, scientists expect that black holes would spin as well, based on how they form. Astronomical evidence has shown that black holes do have spin, though researchers don’t know what the typical spin value is for an astrophysical black hole.

New black hole map depicts 'largest-ever volume of universe'

The team of scientists, led by New York University in the US, said that the map could help understand dark matter better, as the galaxies hosting these quasars are surrounded by 'massive halos' of the invisible matter exerting gravity, but not colliding with particles.
