May 2022 skywatching highlights: Morning planets, a total lunar eclipse, and the second-closest open star cluster, which hangs out near the lion's tail.

Listen closely to new sounds from Mars recorded by NASA’s Perseverance Mars rover.

April 2022 skywatching highlights: Two planetary pairings make April mornings special – Mars and Saturn, and Venus and Jupiter. Plus a special "double star" to look for in the Big Dipper.

Following critical mirror alignment steps, the Web team is confident the observatory will meet or exceed its science goals.

As millions of people across the United States experienced a total eclipse as the umbra, or moon’s shadow passed over them, only six people witnessed the umbra from space.

When depicting an eclipse path, data visualizers have usually chosen to represent the moon's shadow as an oval. By bringing in a variety of NASA data sets, visualizer Ernie Wright has created a new...

Whoa! It’s the middle of the day—so why is the sky getting dark? It’s a solar eclipse! A solar eclipse happens when, at just the right moment, the moon passes between the sun and Earth.

This video explains how our moon creates a solar eclipse, why it's such a rare event to see, and how data from NASA's Lunar Reconnaissance Orbiter has enhanced our ability to map an eclipse's path ...

It's not often that we get a chance to see our planet's shadow, but a lunar eclipse gives us a fleeting glimpse. During these rare events, the full Moon rapidly darkens and then glows red as it ent...

On Aug. 21, 2017, a solar eclipse passed over North America. People throughout the continent experienced a partial solar eclipse, and a total solar eclipse passed over a narrow swath of land stretc...

While many in the U.S. experienced a total solar eclipse on Aug. 21, 2017, SDO's perspective, observing the Sun from Earth orbit, afforded it a view of a partial eclipse.

From aboard NASA's Armstrong Flight Research Center G-III aircraft, this wide angle video of the moon's umbra was captured as they flew over the coast of Oregon, near Lincoln City at 35,00 feet dur...

A solar eclipse happens when the Moon moves between the Sun and Earth, casting a shadow on Earth, fully or partially blocking the Sun’s light in some areas. This fact sheet explains more about sola...
