Hubble's pics of Pluto: Dark orange and charcoal-black

Blogging on EARTH

Today NASA released new Hubble images of dwarf planet Pluto — and far from being just an icy colorless rock, the images show a mottled, dynamic, orangey-black world that changes color with the seasons (on Pluto, the change of seasons lasts 248 Earth years — and although on Earth the seasons change due to the axial tilt of the planet, Pluto's eccentric, non-circular orbit plays a big role in its seasonal variations).
