According to research published on Friday in the journal Science Advances, astronomers have found a first-of-its-kind tailless comet whose composition may offer clues into long-standing questions about the solar system's formation and evolution. Named after a breed of cats without tails, the so-called "Manx" comet was made of rocky materials that are normally found near Earth. Most comets are made of ice and other frozen compounds. And most were formed in solar system's frigid far reaches. Researchers believe the newly found comet was formed in the same region as Earth. Then, as planets jostled for position, it booted to the solar system’s backyard like a gravitational slingshot. Scientists involved in the discovery now seek to learn how many more Manx comets exist. The discovery could help to resolve debate over exactly how and when the solar system settled into its current configuration. http://feeds.reuters.com/~r/reuters/topNews/~3/p5U5Z5p-6Ck/us-space-comet-idUSKCN0XQ2HZ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
