Sun rays on Mars
Sun rays on Mars NASA's Curiosity rover recently captured this image of the setting sun’s rays shining through iridescent clouds high in the Martian atmosphere. Although we see rays like this all the time on Earth around dawn and dusk, it was the first time that the phenomenon (also known as sunbeams or crepuscular rays) has been seen so clearly on Mars.
