Cosmic Dawn: Pursuit of the First Galaxies – Dr. Richard Ellis

(January 16, 2008) Dr. Richard Ellis discusses how using a pioneering technique called “gravitational lensing” allows an international team of astronomers to measure traces of the very first galaxies formed after the Big Bang. Richard, the Steele Professor of Astronomy at the California Institute of Technology, and his colleagues have made remarkable progress uncovering the evolution of the early Universe – the light they measure began its journey to the Keck telescopes more than 13 billion years ago.
