The silvery moon turned red in yesterday's first total lunar eclipse in three years. The change in color was caused by the refraction of the sun's rays through the Earth's atmosphere.Lunar eclipses, which occur when the Earth passes between the sun and the moon, are relatively uncommon events because the moon spends most of its time either above or below the plane of Earth's orbit but you won't have to wait long if you missed this one. There will be another one August 28th.
