Not so fast ...
COMET ISON—UPDATE: New images from SOHO show something emerging from behind the sun. It could be a small fragment of Comet ISON’s nucleus or perhaps a “headless comet”—a stream of debris marking the remains of the comet’s disintegrated core. Watch the movie and stay tuned for updates.
Not to worry. It is the Destiny, now uncloaked and refueled from the passage close to the sun.
