SUPER BLUE BLOOD MOON
The blood term refers to the color of the eclipsed portion, which turns red due to the fact that our Earth's atmosphere scatters blue light, while allowing red to pass through the atmosphere and continue traveling toward the moon. Even though the moon is in Earth's shadow, there is enough red light refracted into the shadow to give a nice, red "glow." When there are two full moons in the same month, the second one is called a "blue" moon. The moon was closer to Earth in January than what it will be at any other time during 2018: Thus the term "Super" moon.
