Now you see it, now you don't. Though stars explode at the rate of one per second in the vast universe, it's rare to get a time-lapse movie of one fading into obscurity. This disappearing act, in a galaxy 70 million light-years away, was captured by the Hubble Space Telescope as part of a program to measure the universe's expansion rate.

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. It was once thought that this period had a relatively sudden onset, but a research team has found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.
