Episode 172: The Hubble Not-So Constant

Feature Guest: Sherry Suyu The Hubble constant, which measures the expansion rate of the cosmos, may not be a constant after all, and if that's true it means we're missing something big in our understanding of the universe. Today we're joined here at The Star Spot by Sherry Suyu, who leads the aptly named H0LiCOW project which uses the phenomenon of gravitationally lensed quasars to measure the expansion rate of the universe. Current in Space Tony reports on a fascinating yet circumstantial finding that suggests a world literally on fire is out there, and it may excite fans of the Star Wars franchise. Then Amelia and Tony break down a study hinting at the existence of exoplanets that may be even more habitable than Earth! About Our Guest Sherry Suyu is a Max Planck Research Group Leader at the Max Planck Institute for Astrophysics, an Assistant Professor at the Technical University of Munich, and a Visiting Scholar at the Academia Sinica Institute of Astronomy and Astrophysics.
