An amateur astronomer has discovered that something has crashed into Jupiter, leaving a bruise the size of the Pacific Ocean near itâÂÂs south pole.Â
    The Australian astronomer, Anthony Wesley, caught sight of the âÂÂbruiseâ probably left by a comet. At first he seemed like he was going to quit and watch TV, but he decided to take another look and was surprised at what he saw. Wesley later e-mailed other astronomers, among them Dr. Fletcher, who was able to bring this to other astronomers.Â
    âÂÂThis is a big event,â says Fletcher. âÂÂIn the inner solar system it would have looked like a huge disaster.â Using NASAâÂÂs infrared telescope facility on top of HawaiiâÂÂs Mauna Kea, Dr. Fletcher and his colleague Glenn Norton saw through the infrared telescope and JupiterâÂÂs âÂÂscarâ showed up as a bright spot. Surprisingly this has happened before, in July 1994. Dr. Marchis stated in an e-mail that âÂÂHumans should be thankful for Jupiter.â Whatever hit Jupiter could have been pulled by JupiterâÂÂs huge gravity before it hit. He had this to say in an e-mail, âÂÂThe Solar System would be a very dangerous place if we did not have Jupiter. We should thank Jupiter for suffering for us. Itâ strong gravitational field is acting like a shield, protecting us from comets coming from the outer part of the solar system.â  Â
