The First Ever Image Of A Black Hole The first-ever image of a black hole is now revealed. it is taken by the event horizon telescope (EHT). the supermassive black hole pictured is at the center of Messier 87, a massive elliptical galaxy in the constellation Virgo. it is located 55 million light years from earth and has a mass 6.5 billion times larger than our sun. this is a huge achievement, not only because it confirms Eintsines general theory of relativity, but because it opens up the possibility for visual observation of a black hole immediate environment. Do you know what are black holes and how do they form? Most people think of a black hole as a voracious whirlpool in space, sucking down everything around it. But that’s not really true!
