Those most angry of birds, the Angry Birds, are celebrating the fact that NASA's New Horizons mission has almost reached Pluto with a new level pack for Angry Birds Space.
This time, we're somewhere familiar: our own solar system, with 15 levels based on the planets, moons, and asteroid belt we all know and love and must one day escape to when we finally destroy the Earth.
These levels also feature new smart bombs which, when struck by a bird, will home in on and blow up a bad piggy. But also give you cosmological trivia. It's all part of Rovio's push to make Angry Birds more educational.
