The AstroPod July 2009

Welcome to the July edition of the AstroPod! This month we're talking with Dr Nic Ross from Penn State University about the elusive dark energy and how astronomers have designed a new survey that hopes to determine its nature. With Anna away, Michelle tells us about the turbulent history of the cosmological constant, and Alex gives out some tips on observing the night sky this month. Be sure to catch Quinton as the unwilling victim for the Joke of the Month! Sit back, enjoy and don't forget you can find more info on our website at http://www.ast.cam.ac.uk/astropod
