A new comet in the frigid outer reaches of the solar system may be an old friend, and it could put on a dazzling display in late 2013 or early 2014. But take it with a grain of salt: I’m old enough to remember the hype of Comet Kohoutek AKA the dud:
Nat’l Geo– Even with powerful telescopes, comet 2012 S1 (ISON) is now just a faint glow in the constellation Cancer. But the ball of ice and rocks might become visible to the naked eye for a few months in late 2013 and early 2014—perhaps outshining the moon, astronomers say.
The comet is already remarkably bright, given how far it is from the sun, astronomer Raminder Singh Samra said. What’s more, 2012 S1 seems to be following the path of the Great Comet of 1680, considered one of the most spectacular ever seen from Earth. “If it lives up to expectations, this comet may be one of the brightest in history,” said Samra, of the H.R. MacMillan Space Centre in Vancouver, Canada.
