In January 2000, John Dubinski set out to calculate the final fate of our galaxy, the Milky Way, and that of our nearest neighbor, Andromeda. The Andromeda galaxy is actually falling towards the Milky...
It means that Silk and Ree's theory may be right and if it is also right that supermassive black holes helped trigger star formation, then it must mean that all giant black holes and their galaxies ar...
Silk realized that the energy from this newly formed quasar would create intense temperature changes in the surrounding gas. This would cause the gas around the black hole and its newly formed quasar...
This correlation is the most important thing we've learned about supermassive black hole so far. Astronomers are always looking for correlations. Whenever you find one that's really tight like this on...
Those stars don't feel the black hole. They feel the rest of the stars in the galaxy. They don't know or care that the black hole is there. If you took the black hole away from the galaxy, they would...
If, as it now seems, every single galaxy has a black hole at its heart, this can't be a coincidence. Perhaps black holes are an essential part of what galaxies are and how they work. No one had expect...
Four times a year, Ghez focuses the telescope on the stars of the very heart of our Milky Way. She is looking for the telltale high speeds that reveal the presence of a black hole. The center of the M...
In every galaxy scientists looked at, they found evidence for a supermassive black hole. NGC 3115 NGC 3377 NGC 3379 In M31 and M32 In total there is probably 20-30 or so black holes that have been fou...
When it's feeding, a giant black hole creates a bright burning gas disk around it and then for some reason, it stops feeding, leaving a dark, deadly core lurking menacingly in the center of the galaxy...
When the results came down from the telescope he saw something that was completely unexpected. The picture from the active galaxy where he hoped to find a black hole was unreadable. NGC 1068 was just...
