Astronomers have discovered strange and unexpected behavior around the supermassive black hole at the heart of the galaxy NGC 5548.

Active supermassive black holes discovered in merging galaxies

A team of astronomers have found at least one supermassive black holes almost always becomes active and luminous by accreting a large amount of material in luminous, gas-rich, merging galaxies.

How supermassive black holes are formed

Over billions of years, small black holes can slowly grow supermassive by taking on mass from their surroundings and also by merging with other black holes.

How supermassive black holes grow when galaxies collide

Experts have claimed that the notion black holes become supermassive by merging with other black holes is much more complex than previously believed.

NASA`s new black-hole-hunter spacecraft - NuSTAR - has detected its first 10 supermassive black holes, lying at the hearts of distant galaxies between 0.3 and 11.4 billion light-years from Earth.

`Supermassive` black holes may be bigger than thought

Some of the biggest black holes in the universe may actually be even bigger than previously thought, a study that uses data from NASA’s Chandra X-ray Observatory has suggested.

NASA’s Wide-field Infrared Survey Explorer (WISE) mission has uncovered millions of new supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.

Cosmic climate change in early universe `may have stunted black holes`

The early universe, which was warmed by the greediest of black holes, could have stunted the growth of the rest, a new study has revealed.

Black holes `eat binary star partners` to grow

There are two ways to grow a supermassive black hole: with gas clouds and with stars.

`Life may be possible in supermassive black holes`

Supermassive black holes are known to be absolutely uninhabitable and the most destructive force in space.
