For the first time, you can see what a black hole looks like
This week, astronomers revealed the first image ever of a black hole—the gargantuan mass at the heart of nearby galaxy Messier 87. The image, a ring of fire surrounding the blackest of shadows, is a powerful confirmation of Albert Einstein’s theory of gravity, or general relativity, which was used to predict black holes 80 years ago. It is also a feat for the team of more than 200 scientists who toiled for years to produce the image by combining signals from eight separate radio observatories spanning the globe.
