Comet ISON reappears in new NASA images, scientists say nucleus ‘may still be intact’

Despite earlier evidence that comet ISON had burned up and disintegrated during a close encounter with the sun, NASA now believes the comet may have survived the heat. Thats according to late-night analysis from scientists that are part of NASAs comet ISON Observing Campaign. Before this latest discovery, a series of images that showed a comet trail (but no comet) led some observers to declare ISON as an ex-comet. But NASA says ISONs reemergence continues a history of surprising behavior that has seen the comet brighten and dim in unexpected ways. According to the space agency, these variations in brightness are the result of material boiling off the comet and provide valuable clues as to just what ISON is made of.
