Pyramids on the moon?
Astronomical objects like planets and moons are wondrous things. We’ll have to take our scientists’ words for what they’re made of and what’s going on up there, but there are some things even they can’t explain. For instance, this picture of a pyramid on the moon.

The astronauts of the Apollo 17 mission took a picture of the surface of the moon, which came out blank due to overexposure. After returning to Earth, they adjusted the photo, and the results are this pyramidic structure in the background. Conspiracy theorists use this photograph as evidence of aliens building the ancient pyramids of Egypt.
