Jul 27, 2009Observations of distant stars tell us about our own future. Roughly 5 billion years from now, the Sun will begin to swell as a red giant, and the solar system will be transformed into a very different place. -
Sep 3, 2004One of the great mysteries for astronomers is why our Sun's surface is so much hotter than its core. The counterintuitive answer, according to a suite of solar observatories, hinges on the Sun's tangled magnetic field and deep, fiery waves. -
Aug 23, 2004The Genesis spacecraft spent 27 months collecting atoms from the solar wind as they streamed off the Sun's corona. When the Genesis sample capsule comes hurtling back to Earth on September 8, helicopter pilots will be waiting to grab it out of the sky.

Aug 20, 2004The Genesis mission will end September 8th, after capturing the first extraterrestrial samples to be returned since Apollo. The spacecraft has stowed pristine solar wind to help scientists search back in the planetary timeline.

Mar 18, 2004Last November solar observers witnessed the largest solar flare ever observed. This month, the orbiting solar observatory snapped a spectacular image of the Sun ejecting an eruptive prominence, a relatively cooler gas ejection that stretched more than fifty Earth diameters and moved at 45,000 miles

Jul 22, 2003A great mystery about our own star is why its atmosphere is hotter than its surface. By studying microflares, solar physicists believe some of this energy is coming from the smaller but more frequent explosions on our typical dwarf star.

Jul 6, 2003Scientists 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.

Feb 21, 2003Using 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.
