In this Aug. 28, 2007, file photo, the moon takes on different orange tones during a lunar eclipse seen from Mexico City. During a lunar eclipse, the moon's disk can take on a colorful appearance from bright orange to blood red to dark brown and, rarely, very dark gray. On Wednesday, Jan. 31, 2018, a super moon, blue moon and a lunar eclipse will coincide for first time since 1982 and will not occur again until 2037. (Marco Ugarte/AP)
