The Event Horizon Telescope project is expected to release the first images today of the supermassive black hole at the centre of the Milky Way - our galaxy - called Sagittarius A*. The project has been attempting to directly observe the immediate environment of a black hole, which could lead to advances in the study of general relativity and prove the existence of event horizons. ANU cosmologist and astrophysicist Dr Brad Tucker says the scientists are “hoping to see” something similar to the last picture of supermassive black hole M87* taken by the telescope. “What we’re hoping to see is … the stuff happening around the black hole and then a very clear boundary,” he told Sky News Australia. “A black hole, we can’t see it, in fact not even light can escape a black hole but what you can see usually is a very clear boundary of what we call the event horizon where there’s nothing inside and stuff outside.” Dr Tucker said it was akin to “looking at the shadow” of the black hole and the environment it is in.
