AKIPRESS.COM - The sky over Pluto may not be sunny but it’s undoubtedly blue.

NASA’s New Horizons spacecraft discovered Pluto’s blue sky during the historic flyby of the icy dwarf planet in July.

The images of Pluto’s atmospheric haze were beamed down last week and released by NASA on Thursday.

The particles in the atmospheric haze are actually red and gray, according to scientists. But the way the particles scatter blue light is what has everyone excited about the dwarf planet orbiting on the far fringes of our solar system, a twilight zone known more formally as the Kuiper Belt.

“Who would have expected a blue sky in the Kuiper Belt? It’s gorgeous,” Alan Stern, the principal scientist for New Horizons, said in a NASA release about the latest images.
