The Hubble Witnesses Catastrophic Collisions In The Fomalhaut System

This composite Hubble Space Telescope image shows the debris ring and dust clouds cs1 and cs2 around the star Fomalhaut. Fomalhaut itself is masked out to allow the fainter features to be seen. Its location is marked by the white star. Image Credit: NASA, ESA, Paul Kalas (UC Berkeley); Image Processing: Joseph DePasquale (STScI)

For the first time, astronomers using the Hubble Space Telescope have spotted a pair of catastrophic collisions in another solar system. They were observing Fomalhaut, a bright star about 25 light-years away, and detected a pair of planetesimal collisions and their light-reflecting dust clouds. The system is young, and the collisions reflect what our Solar System was like when it was young.
