Can you explain what that is why is it a mystery and how these campfires could be connected to the effect that makes the sun’s corona so hot?
It’s really been a mystery for many many years. It’s a little counterintuitive because you would think if you have a body that’s very hot at the center and relatively cool at the surface it would be even cooler the further you go away. On the country for the sun we have a hot core, a relatively cool surface of just about five and a half thousand degrees, surrounded by a superhot atmosphere of more than a million degrees. It’s as if you would light a fire and as you move further away from the fire it doesn’t get cooler but in fact it really starts to burn you when you’re really far away.
