Mark your calendars now for Wednesday, May 26, for a total lunar eclipse or “blood moon.” This incredible phenomenon occurs when the sun, Earth and the full moon are perfectly aligned so that the moon enters Earth’s umbral shadow in space. It will occur close to the moon’s perigee — the closest it gets to Earth in its monthly orbit. View it in our area just before sunrise. The moon turns reddish during the event because the only light on the lunar surface is filtered by Earth’s atmosphere, which can scatter blue light, but not red light. [Getty Images]
