Every image you've ever seen of a black hole has been a simulation. Until now. "We have seen what we thought was unseeable," said Event Horizon Telescope Director Shep Doeleman.
The supermassive black hole lurking at the center of our galaxy appears to have a lot of company, according to a new study that suggests the monster is surrounded by about 10,000 other black holes.
We know that at the heart of pretty much every galaxy, there is a giant black hole. There is a lot that we know about black holes — and a lot that we don't know, says astrophysicist Marcelo Gleiser.
Scientists have detected a black hole thought to be about 800 million times as massive as our sun that is helping to reveal when the universe filled with starlight.
Just as two kids jumping on a trampoline around each other send waves rippling outwards on the fabric, black holes distort space as they orbit around each other, says astrophysicist Marcelo Gleiser.
A project called the Event Horizon Telescope is analyzing data taken earlier this year using interferometry — and we may be remarkably close to "seeing" a black hole, says astrophysicist Adam Frank.
The white dwarf is whizzing around what researchers think is a black hole at an extraordinary speed — at least twice an hour. It is believed to be a star's closest known orbit to a black hole.
Scientists were studying the properties of the light coming from a quasar — one of the brightest objects in the universe — when the light just seemed to wink out. Now they think they know why.
