This is what our Sun looked like on Thanksgiving Day. There are sunspots across the lower right of the image, visible here as what sunspots actually are – very large magnetic storms, like plasma cyclones.
The picture is from the SOHO gallery of the latest images of the Sun, which has all kinds of different ways of looking at that big, bright, orange ball. This particular image is from the EIT, or “Extreme-ultraviolet Imaging Telescope,” which can isolate different wavele…
Thanksgiving Theremin: "Etude in B-flat minor" by Karol Szymanowski, Grégoire Blanc on theremin, GlassDuo on glass harp.
Originally written for piano, but more haunting in this arrangement. Supported by a grant from the Polish Ministry of Culture.
She’s probably the highest-profile thereminist on the internet, and she’s not above sharing a little wisdom.

SONG: “Six Seconds”
SOURCE: Based on Science News, 2 Oct 2020, “Can AI Detect Disinformation? A New Special Operations Program May Find Out”, as used in the post “Our spaceship just grabbed a piece of asteroid”.
This song started with four chords on a guitar, but was almost entirely arranged as a spacey keyboard loop. I played the chords lying in my bed, as you do, and then thought, huh, OK, I could do something with that meter, that spacing of the notes. …
An image of yeast, originally made by NASA (though the context is now unclear, since the web page Wikimedia Commons sourced the photo from no longer exists).
The name “Hefezellen” literally means “yeast cells” in German.
Beer and bread… and some itchy infections. Yeast.
From the ESA Image Gallery, dated 28 Aug 2020, comes an image of a portion of the Cygnus supernova, a blast wave 2400 light-years distant from a dying star 20 times larger than our Sun. It blew up 20,000 years ago, and is still traveling 350 kilometres per second, or around 784,000 mph. The twisting ribbon is caused by the stuff ejected from the star slamming into the low-density dust and gas of interstellar space.
