Video: We Are All Stardust

When a meteor hits the earth, there is the possibility that it brings something very rare along with it:  cosmic stardust older than our Solar System.   Dr. Philipp Heck uses a combination of astronomy, geosciences and chemistry, to hunt for these presolar grains, which offer glimpses into our galaxy's past.  Read more about Philipp's research and the Pritzker Center for Meteoritics and Polar Studies.

Science at FMNH : Ep. 14 - Presolar Grains & Solar System Formation

Presolar grains are the oldest material in the solar system. These microscopic mineral grains formed before the birth of our Solar System and a small fraction survived in primitive asteroids and comets. Studying them can help us understand the formation of the Solar System and planet Earth.
