For a research paper published in The Astrophysical Journal in May 2023, a team of heliophysicists recruited almost a thousand undergraduate students at the University of Colorado Boulder to investigate the mystery of coronal heating. Temperatures in the corona – the tenuous, outermost layer of the solar atmosphere – spike upwards of 2 million degrees Fahrenheit, while just a thousand miles below, the underlying surface simmers at a balmy 10,000 degrees Fahrenheit. How the Sun manages this feat remains one of the greatest unanswered questions in heliophysics and astrophysics. Scientists call it the coronal heating problem.

The students involved in the study looked at solar flares that happened between 2011 and 2018, using data from the National Oceanic and Atmospheric Administration’s Geostationary Operational Environmental Satellite (GOES) and NASA’s Miniature X-ray Solar Spectrometer (MinXSS) missions. They tried to determine whether the flares could explain how the corona is heated.
