Those willing to stay up very late Monday — or get up really early Tuesday — can check out a lunar eclipse. Astronomers say this eclipse will begin just before midnight Denver time, and totality will last from 1:07 to 2:25 a.m.
Lunar eclipses have two big advantages over solar eclipses: You can look right at them, and they can be seen from wherever you can see the moon rather than only being visible in a narrow track.
This eclipse is the first of several expected over the next two years. That’s because it marks the start of a lunar tetrad. A tetrad is when there are four successive total lunar eclipses — with no partial lunar eclipses in between — each of which is separated by six full moons.
A lunar eclipse is sometimes called a “blood moon.” It looks red because of refraction of sunlight by Earth’s atmosphere.
