I recently read a treatise on optical effects such as rainbows and glories. These can occur in any environment in which there is a intervening medium such as raindrops in which sunlight can be refracted. It occurred to me that these can happen on Saturn's moon Titan which possesses a thick nitrogen atmosphere and experiences methane rain.
