What is the "super blue blood total lunar eclipse"? According to Cui Wenyuan, a professor of astrophysics at Hebei Normal University College of physics science and information engineering, this is the "blood moon moon total lunar eclipse Super blue moon" three one astronomical wonders, from the last 152 years there has been. We know that when the moon, the earth, the sun is in a straight line, in the middle of the earth, the moon all into the earths shadow, formed a total lunar eclipse. So, why is the "blood month" formed? "Blue moon" refers to the blue moon? How does the "super"? Listen to the experts one by one. The eclipse is divided into penumal eclipse, partial eclipse and a total lunar eclipse. The middle part of the earths shadow called the uma uma, penuma around. The moon enters the earths penumal penumal eclipse occurs, part of the moon enters the earths umal eclipse occurs, all entered the earths uma total lunar eclipse occurs. The total lunar eclipse, the earth thick atmosphere of the shorter wavelength violet, blue, green and yellow light are absorbed and scattered out, leaving only the red light is refracted through the atmosphere to the surface of the moon (red sun truth like dawn and dusk), so we see in the night sky becomes a red moon, is the "blood"."
