New 'sun-grazing' comet captured

Washington: The European Space Agency (ESA) and NASA's Solar and Heliospheric Observatory, or SOHO, has captured an unusual comet skimmed past the sun on February 18-21, 2015.

This comet was interesting for two reasons. First it's what's called a non-group comet, meaning it's not part of any known family of comets.

Most comets seen by SOHO belong to the Kreutz family, all of which broke off from a single giant comet many centuries ago.

The second reason it's interesting is because the vast majority of comets that come close enough to the sun to be seen by SOHO do not survive the trip.

Known as sungrazers, these comets usually evaporate in the intense sunlight. This comet made it to within 2.2 million miles of the sun's surface, but survived the trip intact.

Karl Battams, a solar scientist at the Naval Research Lab in Washington, said that there's a half-decent chance that ground observers might be able to detect it in the coming weeks, but it's also possible that events during its trip around the sun will cause it to die fairly fast.
