Pluto Reveals a Blue Sky, Floating Ice and a Binary-Style Orbital Dance

New Horizons’ Pluto flyby uncovers a blue atmospheric haze, water-ice mountains, and nitrogen-ice glaciers with buoyant blocks, a Pluto–Charon barycentre outside Pluto that makes them orbit in a binary-like pattern, and an orbital period of about 248 years that has yet to complete an observed year since 1930, illustrating how exotic ices and weak sunlight create a dynamically active world far from Earth.
