asteroid belt http://wrkf.org en Asteroid Belt May Be Just One Big Melting Pot Of Space Rocks http://wrkf.org/post/asteroid-belt-may-be-just-one-big-melting-pot-space-rocks The asteroid belt, a ring of rubble between Mars and Jupiter, has sometimes been written off as discarded leftovers from the solar system's start. But new research <a href="http://www.nature.com/nature/journal/v505/n7485/full/nature12908.html">published in the journal <em>Nature</em></a> shows that the belt actually formed during an unruly later era, when planets themselves were on the move.<p>For decades, astronomers have thought the belt formed from the same cloud of dust and rock that made our planets. That theory was based on observations of just a few asteroids in the 1980s. Thu, 30 Jan 2014 08:30:00 +0000 editor 21924 at http://wrkf.org Asteroid Belt May Be Just One Big Melting Pot Of Space Rocks
