    EXPLOSION ON JUPITER
    Apparently, something hit Jupiter during the early hours of Sept. 10th (11:35 UT), igniting a ferocious fireball in the giant planet's cloudtops. Amateur astronomer Dan Peterson Racine, Wisconsin, saw it first through his Meade 12" LX200 telescope. "It was a bright white flash that lasted only 1.5 - 2 seconds," he reports. Another amateur astronomer, George Hall of Dallas, Texas, was video-recording Jupiter at the time, and he confirmed the fireball with this video screenshot: The fireball was probably caused by a small asteroid or comet hitting Jupiter. Similar impacts were observed in June and August 2010. An analysis of those earlier events suggests that Jupiter is frequently struck by 10 meter-class asteroids--one of the hazards of orbiting near the asteroid belt and having such a strong gravitational pull.

    Astronomers around the world will now begin monitoring the impact site for signs of debris--either the cindery remains of the impactor or material dredged up from beneath Jupiter's cloud tops. Some impacts do produce such debris, while others don't. Researchers aren't sure why; perhaps this event will provide some clues. Stay tuned for news about what happens next.

    JUPITER SWALLOWS AN ASTEROID: Around the world, amateur astronomers have been scanning the cloudtops of Jupiter for signs of debris from an explosion witnessed by Dan Peterson and George Hall on Sept. 10th. So far the cloud layer is blank. "Several observers have now obtained excellent images on the second and third rotations after the fireball, and there is nothing new nor distinctive at the impact site," reports John H. Rogers, director of the Jupiter Section of the British Astronomical Association: JUPITER SWALLOWS AN ASTEROID: Around the world, amateur astronomers have been scanning the cloudtops of Jupiter for signs of debris from an explosion witnessed by Dan Peterson and George Hall on Sept. 10th.

    So where is the debris this time? Perhaps the impactor was small, packing just enough punch to make a flash, but without leaving much debris. Indeed, studies suggest that Jupiter is frequently struck by relatively small 10-meter-class asteroids. In such cases, minimal debris is to be expected.
