"How to take a picture of a black hole," a 2017 TED talk by grad student Katie Bouman who then helped make it happen

Yesterday, scientists revealed the first ever photo of a black hole. Three years ago, Katie Bouman, then a computer science grad student at MIT, led the development of a key algorithm that helped make this historical image possible. In the TED Talk above from 2017, she explained 'How to Take a Picture of a Black Hole.'

'No one of us could've done it alone,' Bouman told CNN yesterday. 'It came together because of lots of different people from many backgrounds.'

In September, Bouman will start her teaching career as an assistant professor at the California Institute of Technology.
