Scientists from around the world have been bombarded with samples of Comet dust gathered from the Wild-2 comet as it recently flew by Earth.

A probe swept up particles from the comet back in January of 2004 and scientists are marveling at the tiny grains, about a millimeter in size, that were returned in a capsule.

The compounds found are very high in nitrogen and oxygen and definitely not inconsistent with theories that propose that the planet Earth may have been bombarded with comets, resulting in the deposit of an organic population of molecules made back when our solar system was formed at which time dense ice clouds were believed to be irradiated stimulating these molecules to create cell like membranes.  This irradiation of molecules has reproduced this action in laboratories and finding the ingredients in the trails of a comet helps to substantiate the possibility.
