@gralefrit.bsky.social You have to see these! A friend of mine has been collating a series of images entitled "Things my students have written turned into Philomena Cunk quotes" and they're just glorious.

One more--this is just so cool:

Firefly Aerospace has released the full image sequence of a solar eclipse from the surface of the Moon. The dark object moving in front of the Sun is Earth. The lunar landscape is lit red by all the sunrises & sunsets in the world. 🧪
