Did you see the "blood moon" total eclipse Sunday night?
The rare event was seen all across San Diego County, reaching its peak at about 8:30 a.m. The moon glowed red after a total lunar eclipse that saw the sun, Earth and moon form a straight line in the night sky. Most Americans had a clear view of it.
During a full lunar eclipse, the moon passes through the darkest part of the Earth's shadow -- the umbra. When the moon is within the umbra it gets a reddish hue because blue and green light get more easily scattered by dust particles in the atmosphere and orange and red colors remain more visible, according to NASA. Lunar eclipses are sometimes called blood moons because of this phenomenon.
About two lunar eclipses occur each year, and the next will be a total lunar eclipse in November.. Then there will not be another total lunar eclipse until March 2025,.
