Capturing the art and science of light! ✈️🌈✨
 
In "Iridescent Contrail", an airplane flying high above dynamic atmospheric conditions creates a vivid iridescent contrail. Sunlight diffracts off water droplets formed by the aircraft's pressure drop, splitting light into a brilliant spectrum of color.
