JUPITER IMPACT? On July 19th, a veteran observer of Jupiter in Australia photographed a fresh dark "scar" in Jupiter's cloudtops; the feature resembles the Shoemaker-Levy 9 impacts of 1994. It is possible that Jupiter has been struck anew by an asteroid or comet. Astrophotographers around the world should train their optics on Jupiter to confirm the event and monitor its progress.
