NASA discovered an electric blue sand dune on Mars — and the photos are mind-blowing
NASA found an exquisite sand dune on Mars over the summer that is literally out of this world.
The photo of the electric blue sand dune was taken in the region of Lyot Crater, a large crater on Mars that is known for its patterned ground — hence the unusual patterns.
"It is made of finer material and/or has a different composition than the surrounding [dunes]," NASA said.
The space agency's Mars Reconnaissance Orbiter (MRO) captured the image, which dates back to January 2018.

The color has been wildly enhanced. It is a dune of fine unknown composition, but no where near this electric blue to the human eye.

Posted by starwatcher-alSolar minimum was in 2019 so the sun is ramping up in flares, spots and prominences.
Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22
