Scientists snare their first ever observations of a solar wave erupting upward from a sunspot

The findings may help explain a deep and abiding solar mystery

Solar scientists have a problem: They haven’t been able to fully explain why the Sun’s atmosphere is about 100 times hotter than its surface.

Now, observations of a solar wave rising up from a sunspot may help explain at least one of the ways in which the atmosphere, called the corona, gets so hot.

Why should the Sun’s atmosphere be hotter than the region below it? If you think about it, this makes no sense.
