The first of two lunar eclipses will take place Saturday morning. The earth will pass in front of the moon and shield it from the light of the sun. The moon will not vanish but will become dark red.
While the moon remains within Earth’s shadow, indirect sunlight still manages to reach and illuminate it, the U.S. National Aeronautics and Space Administration said, explaining why the moon is red during a total lunar eclipse.
” . . . this sunlight must first pass deep through the Earth’s atmosphere which filters out most of the blue colored light,” said NASA. “The remaining light is a deep red or orange in color and is much dimmer than pure white sunlight.”
NASA Also points out that if astronauts were on the moon, they would see a full solar eclipse as the earth passes in front of the sun.
The next lunar eclipse is Sept. 28.
NASA said that the eclipse will be three hours and 29 minutes with totality predicted at 6:01:24 a.m. The space agency said that the eclipse would be visible in the Americas, the Pacific, Asia and Australia.
