Dark Energy is causing the expansion of the universe to speed up – and not to slow down as everyone expected. This discovery overturns astronomers’ ideas about the history and the fate of the universe. Professor Brian Schmidt describes the discovery that won him the Nobel Prize in Physics last year.

Neil deGrasse Tyson On Exploring Cosmic Frontiers
http://www.sciencefriday.com/program/archives/201203024
Many of us spend more time at our desks than anywhere else. Astrophysicist Neil deGrasse Tyson takes us into his office at the Hayden Planetarium in New York City for a tour of his office, in the fourth of Science Friday’s Desktop Diaries series. From a Saturn lamp Tyson made as a kid to his van Gogh pillow, Tyson has a lot of universe-themed paraphernalia. Tyson highlights some of his collection, and talks about what his journey to science stardom has been like.

In Space Chronicles: Facing the Ultimate Frontier, astrophysicist Neil deGrasse Tyson writes of how space exploration — especially human voyages — can profoundly inspire scientists and technologists of the future, and charts the path for missions to Mars and beyond.

Saul Perlmutter: Exploring Supernovae Leads To Physics Nobel Prize : NPR
Astrophysicist Saul Perlmutter is part of the team that was awarded the 2011 Nobel Prize in physics for the discovery that the expansion of the universe is not slowing down but is accelerating. The results of that research suggest the universe is filled with dark energy.

Mysteries Of The Sun
Oh, yon flaming orb. Every day, Helios’s chariot carries you across the sky.
Well, perhaps not: but the 27 million degree star that rules our every waking hour actually has a beating heart. Well, a pulse.
Anyway, it also generates a kajillion fascinating facts — did you know you get more Vitamin D from ten minutes in the sun than 200 glasses of milk?
We explore stories of the star, its eclipses, storms, shelf-life and why somewhere over the rainbow, it’s way up high.

FastForward Radio — Strange New Worlds - Oct 07,2010
http://www.blogtalkradio.com/fastforwardradio/2010/10/07/fastforward-radio--strange-new-worlds
Phil Bowermaster and Stephen Gordon discuss the implications of the discovery of the first potentially habitable planet outside the solar system. What does the existence of Gliese 581g imply about the existence of more such worlds? What does it tell us about the potential for life elsewhere in the galaxy.
If we’re ever to travel to a planet such as 581g, how will we get there? And what will motivate us to go?
