- On January 31, the full moon will be the second in a month, making it a blue moon; it’ll be at the part of the moon’s orbit that defines a supermoon; and there will be a total lunar eclipse.
- The total lunar eclipse is the most exciting for astronomers — it can give the moon a reddish tint, which is why it’s sometimes called a blood moon.
- To catch the eclipse, you’ll need to look up at a certain time: early in the morning in the US, or later that night in other parts of the world.
Early in the morning on January 31 — if you are in the right part of the world — you’ll be able to look up at the sky and see what you could call a “super blue blood moon.”
That’s a full moon happening at the part of the moon’s orbit that’s closest to Earth (known as a supermoon). This will also be the second full moon of a calendar month, which is commonly referred to as a blue moon by NASA and others.
Most excitingly, in certain parts of the world it’ll be possible to see a total lunar eclipse, which can give the moon a reddish hue when the Earth comes between the sun and our satellite, hence the name “blood moon.”
The last time all three of these events happened at the same time was almost 152 years ago. But terms like these can make these occurrences seem more dramatic than they are. Because of where the moon is in its orbit, this full moon will be about 14% brighter than normal — whether or not that qualifies as super is up to you (maybe the moon is always super). And blue moon is not a technical astronomical term — in fact, a different Read More Here
