Incredible microscope images of molecules show what Titan's haze looks like up *very* close

Titan is the largest moon of Saturn, and the second largest moon in the solar system, about the same size as Mercury. Unique among moons, it has a thick atmosphere — despite the lower gravity, the surface pressure is 1.5 times Earth's at sea level.

Its atmosphere is 95% nitrogen (Earth's is 78%) and 5% methane. Normally that would be transparent, but Titan's air is loaded with haze — tiny particles about a micron across (one-millionth of a meter; a human hair is roughly 50–100 microns wide). Th...
