Colossal spiral-shaped flows of super-hot plasma have
been discovered on the sun, completing a nearly 50-year quest to
confirm their existence, scientists say. "You have to have something
like these giant cells to help explain why the sun's equator rotates so
rapidly,"study lead author David Hathaway, an astrophysicist at NASA Marshall
Space Flight Center in Huntsville, Ala., told SPACE.com. These giant solar plasma spirals —
each of which is at least 60,000 miles (100,000 kilometers) wide — could help
spark the formation of strongly magnetic regions on the sun that have
been linked with solar flares and other sun eruptions. Hathaway, Upton
and their colleague Owen Colegrove detailed their findings in the Dec. 6
issue of the journal Science.
