It's a Small World After All

Planets beyond our Solar System are called exoplanets, and they are extremely difficult to photograph. It's like to trying to snap a picture of a firefly against the beam of light from a distant lighthouse. So a range of clever tricks have been developed to detect these faint planets without having to see them directly. But now, astronomers from Japan have managed to photograph a new planet, the least massive planet ever caught directly on camera! In size, it's about three times as big as Jupiter, the largest planet in our Solar System.
