ISON, which spent several billion years at the frigid edge of the solar system before starting a long journey toward the sun, had been billed as a possible “comet of the century.” Its demise seemed to be an anticlimactic ending to the story. But “then it appears again,” said Karl Battams, an astrophysicist at the Naval Research Laboratory who has been observing the comet from Kitt Peak National Observatory in Arizona. “We see something come out.” Images taken by spacecraft showed an increasingly bright point at the head of the comet. Dr. Battams said that current data could not offer a definitive answer, but it appeared Friday that part of ISON’s nucleus was still holding together. nytimes/2013/11/30/science/space/comet-presumed-dead-shows-new-life.html?_r=0
