Orange and Blue Hazes

Explanation: A view from NASA's Cassini spacecraft looking toward the hazy south polar region of Saturn's largest moon, Titan. The moon's high altitude haze layer appears blue here whereas the main atmospheric haze is orange. The difference in color could be due to particle size of the haze. The blue haze likely consists of smaller particles than the orange haze. Will Pluto's atmosphere have haze layers?
