Hubble Space Telescope: Exploding Stars and the Accelerating Universe


April 22, 2015
Location: Washington, DC and Online

Exploding stars halfway across the universe show that the expansion of the universe is speeding up. Astronomers detected this runaway universe with the Hubble Space Telescope in the 1990s and they are using it now to understand the dark energy that causes cosmic acceleration. Is dark energy a modern version of Einstein's discarded cosmological constant or is it something else? We don't know, but we do know how to find out through observations with Hubble and its successors. This lecture by Robert Kirshner, Clowes Professor of Science, Harvard University, is suitable for ages 13 and up. Admission is free but tickets are required:
