Image of the Week: Fighter Jet Rainbow Vapor The Eurofighter Typhoon “Blackjack” performs at the Ayr International Airshow, UK. At transonic speeds, the local pressure behind the wings drops considerably and the surrounding air is sucked in and supercooled to form a vapor cone of liquid water and ice crystals. When the cone is viewed from a specific angle, the sun is refracted into its constituent wavelengths, resulting in a spectacular rainbow cone that lasts a split second. Images captured with a Nikon D5600 with Nikkor 55-300mm lens. The vibrance, saturation and clarity were enhanced in Lightroom to make the effect more clear. Three consecutive images were panoramic stitched using Microsoft Image Composite Editor. —Kevin Mitchell, University of Glasgow, UK *Link in Bio [2023 #OPNPhotoContest 3rd Place Tie] #Eurofighter #UK #transonic #sun #wavelength #rainbow
