Black Hole

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.

Astronomers observed two arcs of X-ray emissions near a supermassive black hole. They say this shows "black holes can create, not just destroy."
