Explanation:

Photographed on [ http://www.photon-e…] March 13th from Caledon, Ontario, Canada, a bright Moon was surrounded by this lovely halo. Planet Jupiter and stars Procyon, Castor, and Pollux also appear within the circle of lunar light. Castor [ http://www.pantheon…] and Pollux, twins in Greek Mythology, are appropriately bright stars of the constellation Gemini [ http://www.astronom…] while Procyon [ http://www.astro.wi…hr/2943.html ] is the brightest star in Canis Minor [ http://www.astro.ui…]. The circular halo is produced by six-sided ice crystals [ http://meteoros.de/…] in thin high-altitude clouds, which refract the moonlight and give the halo a characteristic radius of 22 degrees. For persistent skygazers such apparitions [ http://www.sundog.c…] are relatively easy to see when the Moon and Sun illuminate [ http://www.astro.ui…] planet Earth's skies.
