This artist's concept shows an asteroid plunging through Earth's atmosphere, headed toward an impact near the coast of the Yucatan peninsula. Research indicates that the impact caused a mass-extinction event that killed most of the dinosaurs and much of the other life on Earth, although some scientists suggest the cause was a series of massive volcanic eruptions.
