Scientists have long wondered why the hot soup of charged particles in our sun's atmosphere gets hotter moving away from the surface of the sun.
New research may have the answer, finding the super-hot nature of the sun's outer atmosphere or "corona" could be due to the intriguing behavior of small-scale waves in this nebulous plasma. These waves, known to scientists as "kinetic Alfvén waves" or "KAWs," are wave-like vibrations of magnetic fields manifested by motions in the sun's photosphere.
