[NOTE: There is some controversy over whether the planet seen in this image exists. Read here for more.]
The previous image shows the discovery of the planet Fomalhaut b, about 25 light years from Earth. This image shows better how they confirmed it was a planet: over the course of two years, the planet moved a tiny bit as it orbited its parent star. It takes over 870 years to circle the star once!
