The Sun is Ready for Its Closeup. First Images from Solar Orbiter!

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.

    Sound can create the heat.

    So can LSD Wildman. Wish I had some to watch that again. Imagine.

    Not to mention that sunspots are actually holes in the photosphere, the centers of which are cooler (about 2000 degrees), than their surroundings. Yup, it doesn’t make sense. And the more you find out about the sun the less sense it makes. In fact, the belief that there is a hydrogen bomb at the center of the sun is totally based on an off hand quip from Big Daddy Arthur Eddington that he thought that it was a possibility.

    There is another more plausible theory: The Electric Sun.

    Same reason the candle flame is hotter at its tip than it is at its blue part right at the wick?

    We witness spectacular coronal mass ejections, most of which come back to the sun. Since the corona is so precise, the not insignificant gravity and magnetic field of the sun may be represent a final limiting point for a process of regular and ordinary ejection.

    I did, however, fail algebra 1 so I could be wrong.
