NASA releases a photo of Pluto eclipsing the sun showing a haze in Pluto’s atmosphere which extends at least 160 km (100 miles) above the surface.
This is one of our first images of Pluto’s atmosphere. [It] stunned the encounter team. For 25 years, we’ve known that Pluto has an atmosphere. But it’s been known by numbers. This is our first picture. This is the first time we’ve really seen it. This was the image that almost brought tears to the eyes of the atmospheric scientists on our team.
