'Despite its great size, Ison was probably torn apart in the immense heat and tidal forces so close to the Sun.
The European Space Agency's experts on the Soho Sun-watching satellite called the death of the comet at about 21:30 GMT.
"Our Soho scientists have confirmed, Comet Ison is gone," Esa's twitter feed announced.'
RIP Ison.

a soho movie showing something emerging from the far side of ISON's encounter with the Sun: "Whether this is a small scorched fragment of Comet ISON's nucleus or perhaps a "headless comet"--a stream of debris marking the remains of the comet's disintegrated core--remains to be seen."

<<ISON refuses to die. Maybe it’s perspective or better illumination of the comet’s dust through forward scattering (backlighting by sunlight – like seeing someone’s breath on a cold day) or further vaporization of the remaining chunks of ISON’s nucleus. Whatever the cause, the comet has clearly brightened over the past six hours. Around 6 o’clock Thursday evening, ISON was fainter than first magnitude Antares. Now it’s at least magnitude 0. Bring it on!>>
