Spectacular 22° Lunar Halo Wall Art including Frame Canvas Image Credit: NASA's Goddard SpaceA spectacular lunar halo known as a 22 halo formed in the sky above ESOs La Silla Observatory. The optical phenomenon is a result of moonlight interacting with millions of ice crystals suspended in the atmosphere, forming a ring with an apparent radius of approximately 22 around the moon. It is also known as the moon ring or winter halo. While this is a beautiful sight, it creates conditions which are not optimal for astronomical observations. Clouds
