If you missed the super blue blood moon everyone was talking about this week, don't fret. You'll have more chances within the next year to see cool lunar sightings—though you'll be waiting until 2037 for all three factors to line up at the same time.
A quick refresher on all these names: Last night much of the world saw a lunar eclipse, when the Earth passes between the sun and the moon and our planet's shadow falls on Luna. The nickname "blood moon" comes from the fact that light passing through Earth's atmosphere bathes the moon in a rosy glow.
A blue moon is the second full moon within a calendar month. A supermoon, meanwhile, means a full moon when our natural satellite is at perigee—its closest point to the Earth, when it appears slightly larger in the sky. All three of these phenomena lined up for the "super blue blood moon" this morning.
The next super blue blood moon will happen exactly 19 years from now, on Jan. 31, 2037. That's a long time to wait. Consider, though, that the last one before today's was in December of 1982, more than 35 years ago.
You won't have to wait nearly as long to see the individual circumstances that make up the super blue blood moon. While we say "once in a blue moon" to indicate something relatively rare, the next blue moon is coming right up on March 31, 2018. The repeat blue moon is because of a quirk in the calendar: There is no completely full moon in February (a non-event event that's given the name "black moon"), which means there's a full moon in early March and another one before the month's end.
The next total lunar eclipse ("blood moon") will occur on July 27, 2018. will be totally visible over parts of Africa and Asia. The next supermoon will come later this year during the full moon of Dec. 22, 2018.
These two factors come together for a "super blood moon" on . Get out your binoculars and have a look at this one. It'll be visible from start to finish over the entire United States, and it will look just as impressive as the "super blue blood moon" this morning. The only part you'll be missing is the blue moon, which is an arbitrary artifact of our calendar system.
