Posted on March 18, 2020 as an Astronomy Picture of the Day, this serene Florida seascape captures anticrepuscular rays—sunset light beams that seem to fan out from a point opposite the Sun—arching over the narrow sand spit of Dry Tortugas National Park. Although they look supernatural, these pastel pink and blue rays are a geometric trick: sunlight streaming through gaps in distant clouds travels in straight, nearly parallel lines, but perspective makes them appear to converge 180 degrees away from the setting Sun on the other horizon, tracing great circles across the sky.
