In light of the historical Pluto flyby, the internet is more fired up than ever regarding planets and space stuff. New Horizons was a hot topic on Twitter and Facebook on July 14 when the probe gave us the first clear pictures of Pluto (and its tiny moons) since we discovered the dwarf-planet in the ’30s.
Few people hoped to find anything astounding there, but even as the first shots arrived, Pluto was showing several interesting characteristics, including its notoriously big heart. NASA is still sifting through the mountains of data, which promises to yield new information about the formation of the Pluto system, the Kuiper belt, and the early Solar System.
