A section of the Sutter's Mill meteorite, dubbed "Darth Vader," is studied at a lab at the University of California, Davis. The meteorite is made of carbonaceous chondrite, which contains materials that formed the planets of the solar system.

Robert Ward found a piece of the meteorite at a park in Lotus, Calif., on April 25. The 100,000-pound meteorite was blown apart into small pieces as it met the Earth's atmosphere.
On the crisp, clear morning of April 22, a 50-ton asteroid slammed into the Earth's atmosphere and shattered into countless pieces. Remarkably, they rained down onto Sutter's Mill, Calif., the exact spot where gold was discovered back in 1848, triggering the gold rush. And so follows a story of serendipity and scientific discovery.
