A meteor, or comet or other interstellar object, crashed into Jupiter the other day, and created an explosion so massive that it was visible from earth. Not visible from the naked eye, but large enough that a couple of large telescopes pointed at Jupiter were able to observe it. And, they caught it on video! Watch for yourself!
Apparently, it happens with some regularity, but man is that a cool video.
