The Earth’s shadow will envelop the full moon in a on this day. Observers throughout most of the country will get a partial eclipse, where Earth’s shadow slowly darkens the moon’s surface in the early morning hours on May 26. The moon will turn a bright orange-red—a result of light waves from the sun scattering around the Earth’s edges. The colorful effect earned the phenomenon the nickname “blood moon.”
For those along the westernmost edge of California who will be able to view the total eclipse, the show will start at 3:11 a.m. Pacific time.
