Explanation: Why are the regions above sunspots so hot? Sunspots themselves are a bit cooler than the surrounding solar surface because the magnetic fields that create them reduce convective heating. It is therefore unusual that regions overhead -- even much higher up in the Sun's corona -- can be hundreds of times hotter. To help find the cause, NASA directed the Earth-orbiting Nuclear Spectroscopic Telescope Array (NuSTAR) satellite to point its very sensitive X-ray telescope at the Sun. Featured here is the Sun in ultraviolet light, shown in a red hue as taken by the orbiting Solar Dynamics Observatory (SDO). Superimposed in false-colored green and blue is emission above sunspots detected by NuSTAR in different bands of high-energy X-rays, highlighting regions of extremely high temperature. Clues about the Sun's atmospheric heating mechanisms come from NuSTAR images like this and shed light on solar nanoflares and microflares as brief bursts of energy that may drive the unusual heating.

Just the act of publishing that picture raised earth’s overall temperature by .00023 degrees.
It’s a very subdued (for him) Kanye West. Hah.
LOL
Please add me to the ping list. I enjoy these mesmerizing images and they give me an energy boost, too boot.
You are added to the ping list!
Great as always !
Scenery is spectacular !
Didn’t know Colorado had Moose !
What would the sun look like when a CAT scan is done?.....
