Comet ISON is on track to pass through the sun's atmosphere, or corona, Thursday, potentially giving scientists a spectacular glimpse into several solar mysteries.
The strongest solar storm of the summer so far could send a wave of charged particles toward our planet that could supercharge northern lights displays, NASA scientists say.
For the first time, scientists have caught a glimpse of a comet's final minutes before it was vaporized by the sun. The comet was flying at about 1.4 million miles an hour.
Comet Lovejoy defied expectations and survived its closest approach to the sun late Thursday, leaving scientists the rare opportunity to chronicle a comet's near-death experience.
