While we're browsing vimeo, I see that the Field Museum's Robert A. Pritzker Center for Meteoritics and Polar Studies have recently posted a video about pre-solar grains. The video is here and the web site notification here.
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 and his team of scientists use a combination of geosciences, chemistry, and astronomy to hunt for these presolar grains, which offer glimpses into our galaxy's past.
