Here's something you don't see every day: a tornado on the surface of
the sun. NASA's Solar Dynamics Observatory posted this stunning video,
which shows the sun's plasma sliding and spinning around in the star's
magnetic fields for 30 hours earlier this month.
Terry Kucera, a solar physicist with NASA's Goddard Space Flight Center,
told Fox News
that the tornado might be as large as the Earth itself and have gusts
up to 300,000 miles per hour. By comparison, the strongest tornadoes on
earth, F5 storms, clock wind speeds at a relatively paltry (though
incredibly destructive) 300 mph.
The
sun is an extremely active star, regularly spitting radiation and atomic
particles into space. This space weather has direct impacts here on
Earth, like
forcing the rerouting of planes and
lighting up the auroras.
