Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and less massive than its home galaxy.

The film's visual effects company created a computer code that more accurately portrays a spinning black hole, and this code could be easily rendered for scientific use.

Interstellar gas is the lifeblood of a galaxy, and when it runs out of gas, the galaxy becomes a dead remnant of its former self. (That's also how we feel after eating Thai.)

Someone dimmed the lights in space. Scientists observe a dimming quasar for the first time ever, and this could lead to a understanding of the mysterious black holes and their lifespans.

Detailed analysis of different stellar populations in the disk of Andromeda suggests the galaxy may have had a far more violent history of mergers with smaller galaxies than the Milky Way, researchers from the University of California, Santa Cruz report in a new study.

The stage has been set for a explosion of apocalyptic proportions, as two distant supermassive black holes just one light-year apart are on a collision course that could result in the destruction of their home galaxy and release as much energy as 100 million supernovas.

black hole outburst

After years of watching, astronomers have recorded the largest-ever flare in X-rays from the supermassive black hole located at the center of the Milky Way, and their discovery brings the scientific community one step closer to understand how black holes behave.

Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
