Editor's note: The total phase of the Super Flower Blood Moon lunar eclipse has ended. You can read our wrap story on the first total lunar eclipse of 2022.
A Blood Moon total lunar eclipse will occur this weekend, and here's when to watch it.
The sun, moon and Earth will align Sunday night for a total lunar eclipse on May 15, which occurs when the Earth moves into place between the sun and the full moon. As a result, the Earth casts a giant shadow across the lunar surface, giving the moon a striking reddish hue — which is why lunar eclipses are also referred to as blood moons.
Sunday's full moon is also considered a supermoon, meaning it looks bigger and brighter than usual because it's at the closest point to Earth in its orbit, also known as perigee.
The total lunar eclipse will be visible from portions of the Americas, Antarctica, Europe, Africa and the east Pacific. Meanwhile, a penumbral eclipse, where the outer part of Earth's shadow blankets the moon, will be visible in New Zealand, eastern Europe and the Middle East.

Depending on your location, a partial lunar eclipse begins May 15 at 10:28 p.m. EDT (0228 GMT on May 16). The Blood Moon will reach its peak at 12:11 a.m. EDT (0411 GMT) on May 16 before the lunar eclipse ends at 1:55 a.m. EDT (0555 GMT). The penumbral moon phase of the eclipse will begin about an hour earlier and end about an hour after the partial eclipse, according to TimeandDate.com (opens in new tab).
Viewers lucky enough to be in the path of the lunar eclipse will have to get outside early to witness the event. There will also be some livestreams available on YouTube from NASA Science Live (opens in new tab), Slooh (opens in new tab) and TimeandDate.com (opens in new tab).
NASA's livestream starts at 9:32 p.m. on May 15 (0132 GMT May 16). It will include a discussion on eclipses, moon science and the agency's moon-landing Artemis program. Slooh, an astronomy learning website, will begin their webcast on May 15 at 9:30 p.m. EDT (May 16 0130 GMT). TimeandDate plans to broadcast the entire lunar eclipse, weather permitting, starting at 10 p.m. EDT May 15 (0200 GMT May 16).
This will be the first of two lunar eclipses in 2022. The next one will take place on Nov. 8, 2022 and will be visible at least partially from Asia, Australia, North America, parts of northern and eastern Europe, the Arctic and most of South America, according to TimeandDate.com (opens in new tab).
