Seeing a Black Hole with a Planet-Sized Telescope - STELLAR (2019x15)

Air date: Jul 03, 2019

It took about a century for black holes to go from impossible, to theoretical, to real. And it was just this year, in 2019, when we finally saw the first picture of a black hole! But how to you take a photo of something so massively dense that not even light can escape its gravitational pull? You use a telescope the size of the Earth!
