These are pictures of Pluto and its buddy Charon made by the New Horizons spacecraft, an interplanetary space probe that was launched as a part of NASA’s New Frontiers program. When New Horizons left Earth, Pluto was still considered a planet by the Humans of Earth. When New Horizons arrived, we had figured out that there are actually other objects in the Solar System that we don’t consider planets and look a lot like Pluto. So us humans demoted Pluto to a ‘dwarf planet’.
It still looks damn cool though.
