Comet Dust

Comet Dust Revises History of Evolution...

Tiny crystals from the Wild 2 comet, captured by NASA's Stardust mission, resemble fragments of the molten mineral droplets called chondrules, shown here, found in primitive meteorites. That similar flash-heated particles were found in Wild 2, a comet formed in the icy fringes of outer space, suggests that solid materials may have been transported outward in the young solar system.
