It hasn't happened in 30 years and it won't happen again for 10 years. The supermoon total lunar eclipse is a great reason to stay up a little later Sunday night.

All weekend we'll see a blood red, larger-than-life moon projecting against the stars. Sunday night's supermoon total lunar eclipse will be visible from all our backyards or we can watch a livestream on NASA's website. It will start around 7PM MST and last until 11:30PM. Since we will still have daylight at 7pm, that's why you need to stay up a little later. The actual supermoon eclipse will only last 1 hour and 11 minutes and will peak at 10:47PM.
