After Mars, NASA announces water ice on Pluto

NASA said the haze particles may be grey or red in colour, but theproducing blue colour indicates the size of the particles. Smaller particles results in the scattering of the blue light. Scientists calls those soot like grey-red particles .
The scientists suggest nitrogen and methane in the upper atmosphere, exposed to the Sun's Titan, Saturn's satellite. Some of them grow to tholins. Eventually they are coated with volatile gas frost and fall to the surface, contributing to its red color., break and combine to form more complex similar to a process first observed on
The data collected from the probe's Ralph spectral composition mapper shows several small zones of water ice on Pluto. Alex Parker from tweeted, "We expected water-ice to be there, but we've searched for water-ice in Pluto's spectrum for decades and not seen it before now".(SwRI)
"Who would have expected a blue sky in the Kuiper Belt?", New Horizons principal investigator Alan Stern of SwRI remarked; "It's gorgeous." "This world is alive [...] It has weather, it has hazes in the atmosphere, active geology."
The space probe has traveled over 100 million
