After taking a photo of the monster black hole in the Milky Way, scientists dream of videos


Fresh from its first image of the black hole at the center of our galaxy, the Event Horizon Telescope is ready to take the next step by capturing films of gas flowing turbulently over a black hole.

The two images of the black hole Event Horizon Telescope (EHT) has produced so far – that of Sagittarius A* in the Milky Way and that of the black hole at the center of the galaxy M87 — are snapshots in time. Black holes are constantly rotating as gas orbits its surface or event horizon, but the images still don’t really show this rotation.
