THIS SPRING, scientists confirmed that in the relic radiation left over from the Big Bang (otherwise called the Cosmic Microwave Background), there are certain large scale features they cannot readily explain. In fact, because of this finding, we may need to modify, amend or even fundamentally change our description of the universe's first moments.

On July 31, three leading members of the Planck research team -- George Efstathiou and Anthony Lasenby of the Kavli Institute for Cosmology at the University of Cambridge, and Krzysztof Gorski, Senior Research Scientist at the Jet Propulsion Laboratory in Pasadena, CA, and faculty member at the Warsaw University Observatory in Poland -- answered questions about what was found and what this means to our understanding of the universe.

A Roundtable Discussion with George Efstathiou, Anthony Lasenby and Krzysztof Gorski What do the latest findings from the Planck satellite reveal? And why do they have scientists rethinking how the universe was born and has evolved? Read a discussion with three leading members of the Planck research team.
