Surprise! Pluto May have Clouds
We could be calling it Cloudgate—”leaked” information from internal emails identifying structures in Pluto’s already hazy atmosphere that could very well be clouds, based on a March 4 article in New Scientist.
The image above shows sections of a New Horizons image attached to an email sent by SwRI scientist John Spencer, in which he noted particularly bright areas in Pluto’s atmosphere. “In the first image an extremely bright low altitude limb haze above south-east Sputnik on the left, and a discrete fuzzy cloud seen against the sunlit surface above Krun Macula (I think) on the right,” he wrote.
