Shoemaker-Levy 9's 10th Anniversary

Chuck1318 writes "July 16 is the 10th anniversary of the first impact of pieces of the comet Shoemaker-Levy 9 on the planet Jupiter. The Planetary Society is marking this occasion with a call for applications for Shoemaker grants to fund "amateur and underfunded professional observers anywhere in the world." Shoemaker-Levy 9 created impact features on Jupiter that were larger than the Earth and helped stimulate the search for possible earth-impacting objects."
