On video: Massive object hits Jupiter -- again
Amateur astronomers say for the second time this summer they've captured something entering the gassy surface of Jupiter -- something massive, like, say, a giant asteroid. Japanese space watcher Masayuki Tachikawa captured the impact on video on Saturday, confirming the observations of his peers.
Earlier this year, on June 3, Chris Go and Anthony Wesley tracked a similar impact -- one of many major sightings in recent years. On July 19, 2009, an asteroid thought to be about 1,600 feet wide crashed into Jupiter. Wesley was the first to spot that collision, leading to calls for more vigilant observation of the planet, including by amateurs. Back in 1994, the comet Shoemaker-Levy 9 disintegrated in Jupiter's gravity, hailing the planet with large chunks.
