An impressive partial lunar eclipse will turn the moon an eerie red for millions of people tonight

On August 27-28, 2026, a remarkable partial lunar eclipse will occur, transforming the moon into an eerie red hue visible to millions worldwide. As the full Sturgeon Moon enters Earth's shadow, up to 96.2% of its surface will be obscured by the darkest part of the shadow, the umbra. During maximum eclipse, much of the moon may appear reddish as sunlight filtered through Earth's atmosphere is refracted and projected onto the lunar surface.

Only a thin sliver of the moon will escape Earth's umbra, creating a bright arc against a dim, rusty-red lunar disk.

The partial lunar eclipse is safe to observe with the naked eye, unlike a solar eclipse, which requires special viewing equipment. To witness this celestial event, head outside on August 28 at 12:12 a.m. EDT (0412 GMT), when the maximum eclipse will take place. About 12% of the world's population, or 987 million people, will be able to view all phases of the eclipse, weather permitting.

Skywatchers across Europe and Africa will also catch a glimpse, though the moon may set shortly after maximum eclipse for many observers, including those in the UK.

To maximize your viewing experience, it is recommended to start observing when the partial phase begins around 10:33 p.m. EDT on August 27 (0233 GMT on August 28). As Earth's shadow progresses across the moon, you will see the lunar disk gradually darkening, as if the phases of the moon have been sped up into a few hours. This unique spectacle is sure to captivate viewers, who can either watch in person or follow along with live streams and updates from Space.com.
