A NASA spacecraft has discovered that there is blue sky and red ice on Pluto.
New Horizons returned its first color images of Pluto’s atmosphere last week, according to a release by NASA, and the images show a bright blue haze. According to a NASA scientist, the color occurs when small particles in the atmosphere scatter light.
“Who would have expected a blue sky in the Kuiper Belt? It’s gorgeous,” Alan Stern, New Horizons principal investigator, said in the release.
But that wasn’t the only colorful finding in the new images: New Horizons also returned photographs of exposed water ice on Pluto’s surface, and the ice is often red. NASA scientists don’t yet understand the reason for this coloration.
