January 31, 2018: A super blue blood moon total eclipse

Created by NASA Wavelength Last updated 1/29/2018

Don’t miss this special performance by our very own moon! On January 31, the moon, for the second time this month, will be a full moon (called a blue moon); it will appear a bit larger due to its orbit bringing it closer to Earth (called a super moon); it will fall in Earth’s shadow as it passes between us and the sun (called a lunar eclipse (total eclipse from some viewing areas)); and it will appear reddish-orange during the eclipse due to refracted sunlight -toward the red end of the spectrum- hitting its surface (called a blood moon). Prepare your students for this four-star performance with background information using the resources below!
