The light from big cities is known to obscure star-gazing for many urban dwellers. But the high wattage from skyscrapers and office buildings is an obstacle for another nighttime phenomenon: the lunar rainbow.
Sometimes called a moonbow, the band of colors is a nocturnal rainbow produced by light — in this case, from a full moon — as it passes through water droplets.
To be fair, not every country mouse sees these ethereal and colorful moonbows on a nightly basis. Moonbows can be seen when the moon is full and low-hanging, on inky black nights when it's raining (or near a waterfall). And they're most common in a handful of places, such as Cumberland Falls in Kentucky; Durham, N.C.; Waimea on Hawaii's Big Island; and Victoria Falls on the border of Zambia and Zimbabwe.
