NASA's Spitzer Telescope Witnesses Asteroid Smashup
Washington DC (SPX) Sep 01, 2014
NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets. Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013. "We think two big asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now ... read more
