How the Sun’s Coldest Sunspot Umbra Powers Its Million-Degree Corona
A new study using the Goode Solar Telescope at Big Bear Solar Observatory has uncovered intense wave energy from the sunspot umbra that could maintain million-degree temperatures in the Sun’s corona. While the finding advances our understanding of the Sun’s coronal heating problem, the mystery isn’t completely solved yet.With data from <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="<div class=glossaryItemTitle>Big Bear Solar Observatory</div><div…
