How Astronomers Measure the Size of the Universe

In the latest episode of the new PBS Digital Studios series PBS Space Time, host Gabe Perez-Giz explains how astronomers measure the size of the Universe. The video draws heavily from the Nobel Prize-winning work by Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess that observed distant supernovae and discovered the accelerating expansion of the Universe.
