Staying in space, did you notice the moon turned red Wednesday morning?
It happened for about an hour during Wednesday's total lunar eclipse.
This is when almost all of the light from the sun to the moon is blocked by the earth. Given the name, 'blood moon', the red glow is caused by the light of the sunset coming through the earth's atmosphere.
The latest eclipse is part of what's called a lunar tetrad, or four lunar eclipses in a row. The first eclipse happened earlier this year in April, and the last two will happen next year. And get this - we won't experience another lunar tetrad until the year 2032!
