Dr. James Green's Budget Presentation

Join the journey as NASA’s Psyche mission team launches in 2022 to explore a unique metallic asteroid orbiting the sun between Mars and Jupiter.

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.

Celebrate Women's History Month with us as we pay tribute to scientists, engineers, astronauts, and leaders who continue to pave the way for future generations of explorers.

NASA’s Psyche mission is preparing for a 1.5 billion-mile (2.4 billion-kilometer) trip to a metal-rich asteroid with the same name.

March 2022 skywatching highlights: Saturn with Venus and Mars in the a.m., the Hyades star cluster, and stars with known exoplanets that you can find without a telescope.

A ground-based image of the total solar eclipse on Aug. 21, 2017 (gray, middle ring), is superimposed over an image of the Sun’s atmosphere, called the corona (red, outermost ring), as seen by ESA ...

The United States was in a prime orbital position and time of day to view the eclipse on April 15, 2014.

The Moon pictured during a lunar eclipse is seen from the International Space Station during a northwest to southeast orbital trek 263 miles above the Pacific Ocean.

A perigee full moon, or supermoon, is seen behind the Washington Monument during a total lunar eclipse on Sunday, September 27, 2015, in Washington, DC. The combination of a supermoon and total lun...

The diamond-ring effect occurred at the beginning and end of totality during a total solar eclipse. As the last bits of sunlight pass through the valleys on the moon's limb, and the faint corona ar...

As millions of Americans watched the total solar eclipse that crossed the continental United States Aug. 21, the international Hinode solar observation satellite captured its own images of the awe-...

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...

A team of three scientists have two minutes to complete an experiment during the 2017 total solar eclipse.

A quick visualization of the over 76,000 measurements we collected through the GLOBE Observer eclipse project on August 21st, 2017, with an estimation of the location of the eclipse shadow througho...

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...
