The moon was formed by a violent, head-on collision between the early Earth and a \u201cplanetary embryo\u201d called Theia approximately 100 million years after the Earth formed, UCLA geochemists and colleagues report.Scientists had already known about this high-speed crash, which occurred almost 4.5 billion years ago, but many thought the Earth collided with Theia (pronounced\u00a0THAY-eh) at an angle of 45 degrees or more \u2014 a powerful side-swipe (simulated in this\u00a02012 YouTube video). New evidence reported Jan. 29 in the journal Science substantially strengthens the case for a head-on assault.The researchers analyzed seven rocks brought to the Earth from the moon by the Apollo 12, 15 and 17 missions, as well as six volcanic rocks from the Earth\u2019s mantle \u2014 five from Hawaii and one from Arizona.\"\"<\/p>\n","protected":false},"author":0,"featured_media":0,"template":"","meta":{"_acf_changed":false,"footnotes":"","_links_to":"","_links_to_target":""},"class_list":["post-1848500","news","type-news","status-publish","hentry"],"acf":[],"yoast_head":"\nUCLA solves the mystery of how Earth got its moon -
