Living in a Dying Solar System
Observations of distant stars tell us about our own future. Roughly 5 billion years from now, the Sun will begin to swell as a red giant, and the solar system will be transformed into a very different place.

Comet Dust Reveals Unexpected Mixing of Solar System Material
Researchers from NAI’s University of Wisconsin, Madison Team are also involved the analysis of comet samples returned from NASA’s Stardust mission.
A new analysis of dust from the comet Wild 2, collected in 2004 by Stardust, has revealed an oxygen isotope signature that suggests an unexpected mingling of rocky material between the center and edges of the solar system. Wisconsin Astrobiololgy Research Consortium (WARC) researchers and their collaborators analyzed oxygen isotopes in crystals of olivine and pyroxene from the comet’s halo. These samples, which reached Earth in early...
