Outrageously Funny Word Dictionary :: Opalescence

👉 In astronomy, opalescence is a phenomenon that occurs when light passes through a gas or dust cloud and reflects off of it. The light then refracts back towards the observer's eye, creating a beautiful, shimmering appearance. This effect can be seen in various celestial objects such as the Sun, stars, planets, and moons, as well as in the atmosphere of other planets like Mars.
