Scientists hope that data gathered during the eclipse will help them to answer questions such as why the corona is so much hotter than the Sun’s surface below it, and where the Sun’s magnetic energy comes from. A better understanding of the corona could help them to better predict space weather, which can affect satellites and power grids on Earth.
