| 説明 | NASA image acquired April 12-13, 2010STEREO Captures Largest Prominence Eruption in 15 YearsThe STEREO (Ahead) spacecraft caught this spectacular eruptive prominence in extreme UV light as it blasted away from the Sun (Apr. 12-13, 2010). This was certainly among the largest prominence eruptions seen by either the STEREO or SOHO missions. The length of the prominence appears to stretch almost halfway across the sun, about 500,000 miles. Prominences are cooler clouds of plasma that hover above the Sun’s surface, tethered by magnetic forces. They are notoriously unstable and commonly erupt as this one did in a dramatic fashion. The video clip shows about 19 hours of activity.To learn more or donwload the high res files go to: stereo.gsfc.nasa.gov/gallery/item.php?id=selects&iid=122NASA Goddard Space Flight Center is home to the nation's largest organization of combined scientists, engineers and technologists that build spacecraft, instruments and new technology to study the Earth, the sun, our solar system, and the universe. |
