Alas, poor ISON. The comet that flew too close to the Sun on Thanksgiving Day appears to have suffered the fate of Icarus — if Icarus had been ripped apart by a solar flare. The video above, taken by space probes on the opposite side of the Sun from Earth, provides a great view of the comet hurtling toward the Sun and then disintegrating. Although there's still some discussion over whether or not ISON still survives as a much smaller ball of rock, ice, and dust, NASA has officially declared the comet dead. Astrophysicist Karl Battams wrote a very nice eulogy.
