Our Typical Dwarf Star
Topic: Sun
07/22/03

Summary: Scientists using the main solar observatory, SOHO, have been troubleshooting a locked antenna for weeks. If not solved, about a third of the year, the prediction of solar storms would be pushed back to a pre-1980's situation.

Neat! Comet Crossing
Topic: Sun
02/21/03
Summary: Using tracking from automated telescopes, solar physicists captured the Sun's fiery greeting to a close-passing comet called NEAT. Initially thought to be a newly formed comet, NEAT turns out to have last visited the inner solar system 37,000 years ago.
