An asteroid has given astronomers quite a surprise after seeming to photo-bomb NASA’s James Webb Space Telescope.

The telescope’s official Twitter account described it as a “teeny, tiny photo-bomb”, but the previously unknown asteroid is thought to be “roughly the size of Rome’s Colosseum [and] between … 100 to 200 metres in length”.
