Recent images taken by instruments aboard the Solar and Heliospheric Observatory (SOHO) show a transfer of magnetic energy from the Sun's surface to the corona. This "magnetic carpet" may solve the 55 year old riddle of why the corona is so much hotter than the surface. The SOI Investigation site is maintained by the Solar Oscillations Investigations group at Lockheed-Martin Solar and Astrophysic Laboratory and Stanford University. The site contains links to the full text of the press release from November 5, 1997 by the Goddard Space Flight Center which controls the spacecraft. It also contains QuickTime movies and still images, and offers explanatory text. Background information, authors and contacts for further information on SOHO are available.
