(PhysOrg.com) -- The field of climate science is nothing if not complex, where a host of variables interact with each other in intricate ways to produce various changes. Just like any other area of science, climate science ...
Scientists studying sunspots have found important clues about magnetic features in their decay that will help understand the evolution and real origin of these mysterious magnetic phenomena. The findings are published in ...
Nearly 5,000 kilometers above the sun's surface lies a century-old question for solar physicists—how are temperatures in the star's upper atmosphere (corona) hundreds of times hotter than temperatures at the sun's visible ...
