March 21, 2007: It’s enough to make you leap out of your seat: A magnetic vortex almost as big as Earth races across your computer screen, twisting, turning, finally erupting in a powerful solar flare. Japan’s Hinode spacecraft recorded just such a blast on Jan. 12, 2007.

“I managed to stay in my seat,” says solar physicist John Davis of the Marshall Space Flight Center, “but just barely.”
Davis is NASA’s project scientist for Hinode, Japanese for Sunrise. The spacecraft was launched in Sept. 2006 from the Uchinoura Space Center in Japan on a mission to study sunspots and solar flares. Hinode’s Solar Optical Telescope, which some astronomers liken to “a Hubble for the Sun,” produces crystal-clear images with 0.2 arc-second resolution. (Comparison: 0.2 arc-second is a tiny angle approximately equal to the width of a human hair held about 100 meters away.) “We’re getting movies like these all the time now,” he says.
This particular movie is visually stunning, but the most amazing thing about it, notes Davis, is where the scene unfolded–in the sun’s chromosphere. “We used to think the chromosphere was a fairly uneventful place, but Hinode is shattering those misconceptions…
