Did you see the sky today?
/Did anyone else see the sky earlier today?It was like a rainbow around the sun, with the inside darker.
Known as a 22 degree halo or a sun halo, the ring is caused by sunlight passing through ice crystals in cirrus clouds within the Earth's atmosphere, the University of Illinois' Weather World Project 2010 explains. (See WW2010's website for diagrams that illustrate how it works.)
