On the 21st of December, a full lunar eclipse took place but instead of turning black, the moon turned red and people are wondering why?
On the night of 20th December and at some places on the early morning of 21st December, 2010, a full lunar eclipse took place. This year’s lunar eclipse also happened to coincide with the winter solstice, making the whole event more remarkable.
This time around, the full lunar eclipse was witnessed clearly by people living in Northern and Central America and one strange thing that was noticed was that instead of turning black or grey, the moon turned red when the lunar eclipse occurred. Many people were baffled as to how come the moon turned red when the earth was blocking out the sunlight and for that NASA has an answer.
According to NASA, the moon turned red during the lunar eclipse "because indirect sunlight is still able to pass through Earth's atmosphere and cast a glow on the moon. Our atmosphere filters out most of the blue colored light, leaving the red and orange hues that we see during a lunar eclipse."
