Wave power can drive sun's intense heat

Science News

A new study sheds light on why the Sun's outer atmosphere, or corona, is more than 20 times hotter than its surface. The research, led by the National Center for Atmospheric Research (NCAR), may bring scientists a step closer to understanding the solar cycle and the Sun's impacts on Earth.

In this cropped, still image from Movie 1, the curved lines are coronal loops, most likely composed of hot plasma flowing along magnetic field lines. Some coronal loops are so long that their tops extend beyond the field of view.

P.S: sorry I don't get to post news everyday, really busy with school.

By the way this and this may be of some use to you.

OMG thanks Archean!
