Jupiter Struck for Third Time in 13 Months

For the third time in just over a year, amateur astronomers have detected a comet or asteroid strike on Jupiter. The observations, made possible by the widespread use of astronomical video recordings, show that impacts on the giant planet occur more frequently than previously thought.

On Friday, a small comet or asteroid slammed into Jupiter's atmosphere, producing a brief fireball that was independently recorded by two Japanese amateur astronomers taking video through their telescopes.
