Scientists Detect Hidden Solar Waves
For over 80 years, scientists have been searching for a special kind of magnetic wave inside the sun to explain why the sun's outer atmosphere, the corona, is millions of degrees hotter than its surface.
Researchers have found direct evidence of "twisting" magnetic waves, known as torsional Alfvén waves, inside the corona using the Daniel K. Inouye Solar Telescope in Hawaii.
The discovery was published in Nature Astronomy.
The finding could help explain one of astronomy's biggest mysteries.
