idk if anyone’s put this up yet but i felt it was good enough to share

The Long Gas Tail of Spiral Galaxy D100 : Why is there long red streak attached to this galaxy? The streak is made mostly of glowing hydrogen that has been systematically stripped away as the galaxy moved through the ambient hot gas in a cluster of galaxies. Specifically, the galaxy is spiral galaxy D100, and cluster is the Coma Cluster of galaxies. The red path connects to the center of D100 because the outer gas, gravitationally held less strongly, has already been stripped away by ram pressure. The extended gas tail is about 200,000 light-years long, contains about 400,000 times the mass of our Sun, and stars are forming within it. Galaxy D99, visible to D100’s lower left, appears red because it glows primarily from the light of old red stars – young blue stars can no longer form because D99 has been stripped of its star-forming gas. The featured false-color picture is a digitally enhanced composite of images from Earth-orbiting Hubble and the ground-based Subaru telescope. Studying remarkable systems like this bolsters our understanding of how galaxies evolve in clusters. via NASA

Lots of cool moments with the crew in this video. They seem very easy-going and friendly. The fact that they're doing EVA and docking tests could imply that this crew might get to fly on future Artemis missions!

Especially liked the EVA training in the neutral buoyancy lab. The underwater audio is so relaxing. It must be very comfy for those scuba divers down there.

The plane of the Moon's orbit is offset from Earth's equator, so the Moon dances north and south throughout her orbit!

The Moon moves in loops and dances around the Earth, but our eyes are too slow to see them.
