What on Earth? Series 3

Eyes in the sky. Watching us from space. Hundreds of satellites showing us the world like we've never seen it before. Capturing images which are breathtaking but bizarre. Objects and phenomena which defy explanation. Baffling phenomena seen from space, what on Earth are they?
