Sun Dies

David Kestenbaum reports on astronomers plans to deal with some future climate changes. A billion years from now the sun will swell and grow brighter as it burns more fuel. By nudging an asteroid into close passes with the earth, they say it would be possible to move our planet into a cooler, more distant orbit. That would buy us a five billion years to figure out what happens when the sun becomes a red giant and engulfs us.
