Evenings with Astronomers: The Intergalactic Medium and New Opportunities for Science – Dr. Chris Martin

Dr. Chris Martin of Caltech explains the ongoing mission to directly observe the vast filaments of gas that connect clusters of galaxies, feed galaxies and create a vast web of matter that connects all matter in the universe. This lecture was delivered on April 10, 2012, at the Fairmont Orchid on the Island of Hawaii to an enthusiastic audience of Keck Observatory supporters.

Here on Keck 2 the 1st of our 2 primary fields has just risen above the horizon, so we are busily collecting photons from distant galaxies.
