NASA has just revealed an amazing photo of Pluto with a blue halo glowing all around it. The image was captured by NASA's New Horizons spacecraft back on July 14, 2015. When this photo was taken, New Horizons was approximately 120000 miles or 200,000 kilometers from Pluto. What caused it? "The smog present in Pluto's atmosphere is thought to be a result of the reaction between sunlight and methane and other molecules," NASA said in a blog.The space agency further explained that this process creates a complicated blend of hydrocarbons that accumulate into tiny haze particles, which disperse blue light. As these particles gradually descend through the atmosphere, they generate several complex horizontal layers that span heights of more than 120 miles, around 200 kilometers. NASA a...
