It's not every day that you can say you lived through a once-in-a-lifetime event, but you'll definitely be able to after tomorrow. On January 31st, three cosmic occurrences will happen all in the same night for the first time since 1866: a lunar eclipse, a blue moon, and a supermoon. According to NASA, all three things happen separately on their own schedules ranging from every few months to every few years, but the rare times they all sync up is known as a super blue blood moon.

We already had a supermoon on New Year's Day, when the full moon was closest to the earth during its orbit and appeared around 14%  larger and 30% brighter than a full moon normally does. Since Wednesday will mark the second time we'll see a full moon in a single month, it's referred to as a blue moon. On top of that, there's also going to be a total lunar eclipse—seeing the moon line up perfectly with the Earth and the sun, and changing to a reddish hue as a result of atmosphere changes.

It will all make for some interesting sky gazing throughout the night, depending where you are. There's going to be a live stream going on if you can't make it outside in time, and you can even find out the best time to look out for it.

Astronomy aficionados and general space nerds will probably want to catch a glimpse of the whole thing, considering it won't be back again until 2168. But if you're into astrology, then tomorrow night is also a great time to plan for the next few months, according to Hello Giggles, as both these phenomena are said to bring great focus and energy along with it.
