In a clip from the NOVA miniseries "The Fabric of the Cosmos," Brian Greene and his fellow physicists ponder the implications of multiple universes

For the first time, astronomers discover pockets of pristine gas formed in the universe's first few minutes

The first man-made object to land on Mars arrived 40 years ago this month, and NASA's Curiosity rover should soon depart for the Red Planet. Here is a look at where humankind's many Mars landers have touched down, and where the planet betrays a history of all-important liquid water. Find out more in Exploring the Red Planet

Listen to the announcement of the 2011 Nobel Prize in Physics, to Saul Perlmutter, Brian Schmidt and Adam Riess, from the Royal Swedish Academy of Sciences. Following the formal announcement comes an explanation of the research, which tracked type Ia supernovae to discover that the expansion of the universe was accelerating, and a phone conversation with new Nobel laureate Brian Schmidt

Saul Perlmutter, Brian Schmidt and Adam Reiss share the 2011 Nobel Prize in Physics for their observations that type Ia supernovae indicate that the expansion of the universe is accelerating. Steve Mirsky reports
