Comet ISON Survives Perihelion 11 29 13

Comet ISON first appeared to have vaporized due to the heat and tidal forces of the sun, but the comet was seen again on the other side of the sun, disintegrated but still visible.

Remnants suggest comet ISON still going

First given up for dead, ‘dirty ice ball’ may have partially survived close brush with the Sun.

Comet ISON entered the annals of astronomical history on the night of 28 November, when it flew past the Sun and, latest updates suggest, emerged in tatters on the other side after many skywatchers had given it up as dead.

Still, the most recent images hint that most of ISON’s nucleus disintegrated as the comet approached the Sun, leaving only a slim chance there will be anything left to see with the naked eye over the northern hemisphere in coming weeks.

Analysis of the light coming from ISON will determine whether it is now just a spray of dust and gas, or any significant portion survived, says Gerhard Schwehm, former head of Solar System Science Operations Division and comet expert at the European Space Agency. “Either there’s only a small piece left, or the nucleus is really totally disintegrated and we just see the debris of the comet travelling along,” he says.

ISON’s future remains unclear, but it has already upended scientific understanding of these ‘sungrazing’ comets. ISON was making its first, and possibly only, journey from the deep freeze of the outer Solar System into the furnace of the star’s outer corona. Never before have researchers followed a comet so pristine coming so close to the Sun.
