Giant Plasma Spirals Found on the Sun
By Charles Q. Choi, SPACE.com Contributor | December 05, 2013

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.
