A pair of solar observatories saw something emerge from around the sun following ISON’s close approach on Thanksgiving Day. But scientists don’t know whether the spot of light was merely the comet’s shattered remains or what’s left of its icy nucleus. Either way, by now, they say it may be just dust.
Over the coming week or two, scientists will keep a lookout for any brightening, which could indicate what, if anything is left. Hubble should put the matter to rest in mid-December, when the comet’s remains are far enough from the sun for safe viewing.
As for us earthlings, there appears to be little chance of spotting what’s left of the comet with the naked eye. Whatever is left will pass closest to Earth on Dec. 26; it will keep a safe 40 million miles (64 million kilometers) away.
ISON was making its first visit to the inner solar system, after traveling from the Oort cloud on the fringes of the solar system, home to countless icy bodies, most notably the frozen balls of dust and gas in orbit around the sun known as comets
