Is it a “space hut”? Is it a cube? It’s probably a strangely-regular boulder, but China’s moon rover has spotted a curious object hiding on the dark side of the moon.

Sadly it will take a couple of months before the rover can get close enough for a decent look and burst sci-fi dreams of a monolith straight out of Arthur C Clarke’s 2001.

On the other hand, the US government appeared to acknowledge the reality of UFOs earlier this year, so who knows?
