Don Ecker is probably the greatest living authority on the subject. Look up his stuff. Here's a video I found with a quick search: https://youtu.be/r1AxmaYdj4g Here's the classic 70s book on the subject: https://archive.org/details/somebody-else-is-on-the-moon NASA did a write up called "*Lunar Transient Phenomena Catalog NASA TR-R-277*" in the 60s. "Lunar Transient Phenomenon" is geek speak for weird fucking shit moving around on the moon that we can't fucking explain.

Weird clouds crawling around, "boulders" that leave tracks climbing UP out of craters, towers, shit that looks like buildings, rumors of the Apollo astronauts seeing flying saucers parked off in the distance. I'm sure there's crazy shit up there, on Mars, and even in Antarctica.
