Blood Moon on Friday!

A “blood moon” is a name given to the moon during a lunar eclipse. A lunar eclipse occurs when the Earth passes between the sun and the moon, casting the moon into shadow.

Unlike with a solar eclipse, when the moon passes between the Earth and sun, blocking the sun’s light, the moon is not “turned dark” during an eclipse, but instead appears to turn red.

“If the Earth was a big smooth ball with no atmosphere that would be the end of the subject, it would just go dark, like with a new moon,” said Chris Tinney, professor in the physics department at the University of New South Wales. “But because there is light scattered through the atmosphere of the Earth, some of the sun’s light gets bounced around the edge of the Earth to hit the moon.”

Because blue and violet wavelengths are scattered more than red and orange ones, more of the red wavelengths reach the moon, making the moon appear red.
