NASA’s Cassini spacecraft took some stellar photos of Saturn’s 1,250 mile-wide polar hurricane. The result were black and white photos when normally developed, however with some post-production, NASA has been able to refine the photos. The Cassini spacecraft uses spectral filters that can detect the subtleties of wavelengths of near-infrared light. All NASA had to do then was false-color the vortex based on those tiny changes, invisible to the human eye. The end product? Deep reds represent lower clouds, and the greens are ones that sit a bit higher than that.
