General Audience


Watch one of the sky’s most dazzling shows in the early morning of May 26, when the Sun, Earth, and Moon align at 4:11 a.m. PDT (7:11 a.m. EDT), creating a total lunar eclipse. Weather permitting, the lunar eclipse will be visible in western North and South America, as well as in eastern Asia, Australia, and the Pacific Ocean. Totality only lasts about 15 minutes for this eclipse, so be sure to look toward the Moon when the time is right. And viewers in the Midwest and the eastern U.S. can still look up to see a partial eclipse grace the sky. Note: Unlike a solar eclipse, you do NOT need special glasses to view a lunar eclipse.

This interactive shows a real-time simulated view of the Moon from space. Use your mouse and the controls at the bottom of the screen to move around and explore more of the Moon and the solar system.  

The full moon will also be near its closest point to Earth in its orbit, called perigee. While at perigee, the Moon appears slightly bigger and brighter from our perspective on Earth, so it’s often referred to as a “supermoon.”

Check out these Teachable Moments and related educational activities to find out how to watch a lunar eclipse and see what causes them to occur – plus learn more about supermoons and whether they're really as "super" as they seem.
