Zippy's Video of the Week: How to Take a Picture of a Black Hole
Unless you've been living in a (ahem) hole, you probably heard about the phenomenal photo of a black hole, captured for the first time last week by a team of scientists from around the world.
In this TEDx video from 2016, one of those researchers, Katie Bouman (now a Ph.D., but then a doctoral student at M.I.T.) explains the theory behind how scientists found a way to photograph the invisible using the Event Horizon Telescope. And now in 2019, we know that their plan worked. Bravo, scientists!
