Remember April 15? No, not tax day. April 15 was the infamous “blood moon,” the first of four spaced out at six-month intervals.
Now, here comes the second blood moon, and Colorado is in a prime viewing position. According to NASA, the full eclipse will start at 4:25 a.m. MDT Wednesday and last until 5:24 a.m.
Blood moons get their name from the fact they can appear red or reddish orange. That is because sunlight is refracted by the Earth’s atmosphere as our planet’s shadow covers the moon.
This is the second in the four eclipses that make a lunar tetrad. A tetrad is when there are four successive total lunar eclipses with no partial lunar eclipses in between — each of them separated by six full moons. (Eclipses 3 and 4 are coming on April 8, 2015, and Sept. 28, 2015.) The Denver Post
