Our galaxy's central black hole, Sagittarius A*, is a gargantuan tear in space-time that is 4 million times the mass of the sun and 14.6 million miles (23.5 million kilometers) wide. But these are ...

This is the gargantuan black hole that lives at the centre of our galaxy, pictured for the very first time. Known as Sagittarius A*, the object is a staggering four million times the mass of our Sun.

A black hole 700 million light-years from Earth has a mass 40 billion times that of our Sun. The ultramassive black hole is located at the heart of Galaxy Holm 15A. Even though this black hole is ...

When galaxies merge, the supermassive black holes that sit in their centers must eventually merge, too, forming an even more gargantuan black hole. For decades, though, a question has vexed ...

What happens when a gargantuan cloud of gas swallows a pair of monster black holes with their own appetites? Feasting on the gas can cause some weird (heavenly) bodily functions. AT 2021hdr is a ...

It's a quasar - the bright core of a galaxy that is powered by a gargantuan black hole some 17 billion times the mass of our Sun. Known as J0529-4351, the object's power was confirmed in ...
