Image by Larry Koehn, from NASA. During the totality, when the moon is completely in Earth's shadow, it will appear to turn red and possibly turqoise. Ozone causes the turquoise color. Red, NASA tell us, is the color of Earth's shadow. (Isn't that poetically rich?) Science explains that dust in Earth's atmosphere redirects the Sun's light, throwing this red shadow.
Today also would have been Kurt Cobain's 41st birthday.
