Earth\u2019s most famous killer asteroid came from the outer reaches of the solar system<\/a>, researchers report in the Aug. 16 Science<\/em>.<\/p>\n\n\n\n

About 66 million years ago, an asteroid slammed into the sea just off Mexico\u2019s Yucat\u00e1n Peninsula, forming the Chicxulub crater. That powerful impact may have triggered a mass extinction event on Earth, killing off more than 60 percent of the planet\u2019s species<\/a>, including all nonbird dinosaurs (SN: 1\/25\/17<\/em>). The impact left geochemical fingerprints<\/a>, such as elevated levels of the element iridium, in a thin layer of rock found in multiple countries around the globe (SN: 9\/8\/84<\/em>).\u00a0 \u00a0<\/p>\n\n\n
