Texas State University astronomers have developed the first method of predicting the appearances of moonbows -- rainbows caused by moonlight rather than sunlight -- at Yosemite Falls in Yosemite National Park.
The hunt for the elusive "moonbow" has long been a nocturnal lure for dreamy hikers, insomniac seamen and intrepid photo buffs. But in the past, seeing one of these nighttime rainbows — caused when a full moon's rays bounce off the mist of a departing rain cloud or raging waterfall — has been dictated mostly by chance.
No longer.
