Blood Moon Live Link:
Earth’s shadow has crept over the surface of the moon, beginning about 20 minutes after 10pm Monday night. The full eclipse gradually turns a normally colorless moon red, hence the “blood moon” moniker. That total eclipse started shortly after midnight Tuesday. It was expected to keep glowing red until around 1:30am.
By definition, lunar eclipses happen when the Earth squeezes between the moon and the sun. The long shadow cast as a result is what causes it emit that signature reddish hue.
These kinds of lunar eclipses happen about two times a year. But, depending on what part of the world you're in, you may or may not see it.
