A ‘blood moon’ will be visible in the desert this weekend thanks to a total lunar eclipse.  Here’s how to make sure you don’t miss it: The eclipse will begin around 07:30pm PST, and reach totality – with the entire Moon inside the Earth’s penumbra – at roughly 08:30pm and continue through 10:00pm.

The ‘blood moon’ refers to the dark red hue projected onto the moon’s surface during totality.  It’s caused by sunlight passing through the Earth’s atmosphere before reaching the Moon.

The eclipse should be easily viewable anywhere in the eastern half of the U.S., and its totality will be viewable anywhere in North America.

But what if it’s cloudy?  Don’t worry – NASA has you covered with a special lunar eclipse livestream an moon.nasa.gov.


The next lunar eclipse won’t happen until November – and the next one after that won’t be until 2025.
