Multispectral rainbow

Dr A. Dominic Fortes, Earth Sciences

These images depict a rainbow photographed in visible light, 420-650 nm (centre), near-ultraviolet light, 380-400 nm (left), and near infrared light, >800 nm (right). The image was acquired using a Fujifilm IS-1 camera with commercially available bandpass filters. The first IR photograph of a rainbow made it into Science in 1971 (Greenler, Science 173, 1231). Infrared rainbows may be common on Titan according to research by atmospheric optics expert Les Cowley due to the combination of visible opacity and IR transparency of methane.
