Did Comet ISON survive? Scientists see tiny hope

In this combination of three images provided by NASA, comet ISON appears as a white smear heading up and away from the sun on Thursday and Friday, Nov. 28-29, 2013.

A comet that gained an earthly following because of its bright tail visible from space was initially declared dead after grazing the sun. Now, there is a sliver of hope that Comet ISON may have survived.

New images being analyzed Friday showed a streak of light moving away from the that some said could indicate it wasn’t game over just yet.

“It certainly appears as if there is an object there that is emitting material,” said Alan Fitzsimmons, an astronomer at Queens University in Belfast, Northern Ireland.

Basically a dirty snowball from the fringes of the solar system, scientists had pronounced Comet ISON (EYE’-sahn) dead when it came within 1 million miles (1.6 million kilometers) of the sun Thursday.

Some sky gazers speculated early on that it might become the comet of the century because of its brightness, although expectations dimmed over time. But it wouldn’t be all bad news if the 4.5-billion-year-old space rock broke up into pieces, because some scientists say they might be able to study them and learn more about comets.

The European Space Agency, which had declared ISON’s death on Twitter late Thursday, was backtracking early Friday, saying the comet “continues to surprise.”

Comet ISON was first spotted by a Russian telescope in September last year, and became something of celestial flash in the pan this week for its vivid tail—visible by the naked eye—and compelling backstory of impending doom.
