As most people know, tomorrow morning (January 31) before sunrise there will be a total eclipse of the Moon. It will not be an ordinary lunar eclipse because it will be a Super Blue Blood Moon. What does that mean?
It’s called “super” because the Moon is at perigee. That means the Moon is at its closest point to the Earth. The Moon’s orbit of Earth is somewhat elliptical so at times it is farther away, and sometimes it’s closer. At the closest point, it is somewhat larger and brighter than when it is at its farthest point, called apogee.
What about the “blue?” One thing for sure, the Moon won’t look blue. This will be the second full moon during January. Two full moons during one month don’t happen very often, only “once in a blue moon” as the saying goes. When we do have two in one month, the second full moon is called a “blue moon.”
Why is it called a “blood moon?” That’s because during a total lunar eclipse the Moon looks red. A lunar eclipse happens when Earth’s shadow blocks the Sun’s light from the Moon. Lunar eclipses only happen when the Moon is at its “full” stage because that is when the Sun and Moon are on opposite sides of the Earth. Only when the Moon, Earth, and Sun line-up perfectly does Earth’s shadow block the Sun’s light from reaching the Moon. However, even during a total eclipse some of the light from the Sun is bent by the Earth’s atmosphere enough that it reaches the Moon’s surface. The bending occurs mostly in the red end of the visible spectrum, so some red light reaches the Moon, and we see that red light reflected back to us. It’s the same red effect we see at sunrise and sunset.
So that’s how we can have a Super Blue Blood Moon. If you want to know when you can see the eclipse in your area, there are many websites that give that information such as NASA.gov.
If someone tries to tell you that this eclipse, or any solar or lunar eclipse, is a sign of some catastrophe or dramatic event that is about to happen, don’t believe it. The dramatic events are the eclipses themselves. The way the solar system has been designed to make life possible and allow us to enjoy watching eclipses is a demonstration of the wisdom and creativity of the Designer. Eclipses allow us to learn more about the system that God has created. We are in awe of this life-giving system.
