Editor’s Note: When EarthSky first published this image, we misidentified it as a photo of iridescent clouds. In fact, it’s a circumhorizon arc. Mistaking one for the other is easy, but here are some tricks that can help. Our thanks to alert reader George Preoteasa for pointing out the mistake … and apologizes for any confusion!
Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
