“Iridescent by Moonlight” is copyrighted by Marcella Giulia Pace. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteWhen the Full Moon shines through thin clouds, something special can happen. Small water droplets in the clouds diffract the moonlight, creating an iridescent glow, a lunar corona. This image from Sicily captures that moment, with the Pleiades star cluster visible nearby. It's a beautiful interplay of light and atmosphere.
