See stunning photos of the last total lunar eclipse until 2025

Early Tuesday, some Americans caught a glimpse of a total lunar eclipse – a phenomenon that won’t happen for another three years.

It’s the first Election Day total lunar eclipse in U.S. history, according to EarthSky.org

The eclipse was also visible in Asia, Australia and the Pacific, according to the website.

It began Tuesday at 3:02 a.m. EST, and totality (when the moon is engulfed in Earth’s shadow) began at 5:16 a.m. EST. The event ended at 6:41 a.m. EST.

A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth, according to NASA., and is also called a blood moon.

When this happens, Earth blocks the sunlight that normally reaches the moon. Instead of that sunlight hitting the moon’s surface, Earth’s shadow falls on it.

Though it has no special astronomical significance, the view of a blood moon in the sky shows a normally white moon turn red or murky brown, according to space.com.

The next lunar eclipse visible in the U.S. will be in March 2025, NASA said.

The next Election Day lunar eclipse will be in 372 years, on Nov. 8, 2394.
