Two wonderful videos showing the impact of a comet on Jupiter. These two different amateur astronomers happened to catch an object impacting Jupiter back on March 17th. Here are their videos.

Jupiter's substantial gravity means that objects hit its atmosphere at much higher velocities than rocks that hit earth. That means much more energy is released for a given impactor size, so it doesn't take a very large rock to make a flash bright enough to be seen from earth. This isn't the first time an impact like this has been caught by amateur astronomers. The proliferation of "lucky imaging" of the planets and video astronomy in the last couple of decades has meant that the major outer planets like Jupiter are now under nearly constant amateur surveillance.
