Astronomers Set to Image Galaxy's Central Black Hole

[Yazata]

They plan to do it with what in effect is a giant telescope the size of the Earth. It's actually eight radio telescopes in six different locations: Arizona, Hawaii(2), Mexico, Spain, Chile(2) and the South Pole! (Who knew that there is a radio telescope at the south pole?)

They will be combined in such a way that they act like small points on a single huge telescope with the diameter of the planet. That should provide unprecedented resolution.

The collection of telescopes will all be directed at what is believed to be the central black hole in the Milky Way galaxy in Sagittarius A, hoping to ideally capture the black hole's event horizon, and certainly the violent movements of stars and gas near the giant black hole.

Depending on which earlier / later claim, the Milky Way's "volcano" has apparently been dormant for either two or six million years. Would have been vastly more detectable if a telescope had been around during its last eruption phase. Needless to say, there are good reasons why life with a long history would favor planets in the rural outskirts rather than the violent interior.
