Looking Back at the Beginning of our Solar System

New signs have been discovered to a possible start of our solar system. It’s very difficult to find evidence of the actual moment, but some chemists have been able to detect some material from an explosion of a star that may have been responsible for the ignition of our star.  Coming back to present, a natural bridge has been discovered on the moon by the Lunar Reconnaissance Orbitor. It looks like it traverses a collapsed lava tube, but without much water and no wind on the moon it must have been created by some geological process. Also, don’t miss Jupiter prominently in the night sky this week. All this and more on this week’s Sky Talk.Also, you can track findings by visiting LRO online.[audio: st20100927.mp3]
