Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our solar system that may have conditions more suitable for life than our own. Some of these orbit stars that may be better than even our sun.

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.
