Science: "This global telescope may finally see the event horizon of our galaxy's giant black hole"

"This year, for the first time, the EHT will add dishes in Chile and Antarctica, sharpening its resolution and raising expectations. Astronomers now hope to see how the black holes whip the hot gas around them into accretion disks and spawn matter-spewing jets. They also hope to chart the size and shape of the event horizon—the boundary of the black hole—to test whether Albert Einstein's theory of gravity, general relativity, still works under such extreme conditions."
