The Solar Corona Is Much Cooler Than The Sun Surface

Clear evidence now suggests that the intense heat of the sun s atmosphere depends on explosive bursts not continuous heating.

The solar corona is much cooler than the sun surface.

She likens it to walking away from a campfire and feeling colder and colder until suddenly getting very hot. But the temperature at the sun s surface the source of that energy is a relatively balmy 5 500 degrees. The temperature in the corona is a blistering million or so degrees celsius. This solution to the coronal heating mystery was presented at a media briefing on april 28 2015.

It s just weird says winebarger. The temperature in the corona is a blistering million or so degrees celsius.
