Looking up stuff about the structure of the Sun and temperatures of different regions.

“The sun is hot, the sun is not a place where we could live.
But here on earth there’d be no life without the light it gives.”



From Goddard Space Flight Center:

“Supergranules cover the Sun’s visible surface (photosphere) in a network, called supergranulation, of cells: irregular bright regions that are horizontal outflows of electrified gas (plasma). Supergranule cells get their name from their resemblance to smaller features in the photosphere called granules. Granules are believed to be convection cells of plasma that transfer heat from the solar interior to the surface. They resemble the cells seen at the surface of a simmering pot of soup, although granules are much larger (about the size of Texas at 1,000 kilometers or about 620 miles across). Supergranules are larger still — at around 30,000 kilometers (18,600 miles) across, they could comfortably frame two Earths. The whole solar surface is covered by several thousands of supergranules.”
