Color image of Venus' glowing atmosphere from Akatsuki's 2-micron camera
Akatsuki captured this photo on March 25, 2016. It is composed of images taken at two infrared wavelengths, 1.735μm (red channel) and 2.26μm (blue channel), which are sensitive to two different sizes of particles in Venus' clouds. A green channel was synthesized from a combination of the two. The orange glow around the terminator results from Venus' long twilight in its thick atmosphere.
