Latest James Klimchuk Stories
The mystery of why temperatures in the sun's outer atmosphere are higher than near the sun's surface may have been solved by Japan's Hinode satellite. James Klimchuk, an astrophysicist at NASA's Goddard Space Flight Center's Solar Physics Laboratory, says new observations by that satellite have revealed why temperatures in the solar corona, the sun's outer atmosphere, soar to several million degrees Kelvin -- much higher than temperatures nearer the sun's surface. The answer is nanoflares --...
