Black mark appears on Jupiter

July 20, 2009

"The jet-black mark is near Jupiter's south pole," Veteran Jupiter observer Anthony Wesley reportedly told "I have imagery of that same location from two nights earlier without the impact mark. So, this is a very recent event. The material has already begun to spread out in a fan shape on one side, and should be rapidly pulled apart by the fast jetstream winds. I recorded a lot of footage, and will be generating more images and a rotation animation soon."

ABC7 meteorologist Mike Caplan says the mark is the size of the planet Earth.
