Ever wonder what the spacewalker sees while you’re looking at him or her? Here’s your answer, courtesy of NASA astronaut Jack Fischer. This Ultra High Definition clip shows Fischer outside the International Space Station during a spacewalk on Expedition 51 in May 2017, and the view from a small camera attached to his spacesuit at the same time.

This visualization traverses the CANDELS Ultra Deep Survey (UDS) field to showcase the varied appearances of galaxies and their three-dimensional distribution. The sequence features a dense cluster of galaxies about 6 billion light-years away and extends to galaxies at more than twice that distance. Because the light from these galaxies has travelled for billions of years across space, the images show the galaxies as they appeared billions of years ago. In addition, the expansion of space has redshifted the light of these galaxies toward longer wavelengths (i.e., to the red end of the visible-light region and into the infrared-light region). The changes seen in galaxies during the fly-through illustrate the changes in galaxy structure and appearance over billions of years of cosmic history. CANDELS is an acronym for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey project. One of the largest projects ever done with the Hubble Space Telescope, CANDELS surveyed five fields to study the development of galaxies over time. The CANDELS observations of the UDS field complement ground-based observations from the United Kingdom Infrared Telescope. Astronomers and visual artists extracted over 26,000 galaxies from the Hubble UDS images and created a computer model based on the measured and estimated properties. Note that the distances used in the visualization are significantly compressed for cinematic purposes. Credits: NASA, ESA, F. Summers, J. DePasquale, G. Bacon, and Z. Levay (STScI)

“Sharing the incomparable silent beauty of our planet with all our fellow travelers on this, our Spaceship Earth.” @SergeyISS @Astro_Paolo @Astrokomrade “Our thanks to Mr. Paul Simon and Disturbed.” “Our thanks to all the people within the partnership of the International Space Station who show us daily what heights we can achieve together.” “The Sound of Silence” Written by Paul Simon. SONGS OF UNIVERSAL, INC. on behalf of PAUL SIMON MUSIC. Performed by Disturbed. Courtesy of Warner Bros. Records. Captured by astronauts Sergey Ryazanskiy, Paolo Nespoli, and Commander Randy Bresnik, the video features stunning footage of Earth and outer space from the International Space Station in low-earth orbit during the months of August through October in 2017.

This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2018, as viewed from the Northern Hemisphere. Each frame represents one hour. In addition, this visualization shows the moon's orbit position, sub-Earth and subsolar points, distance from the Earth at true scale, and labels of craters near the terminator.

The astronauts and cosmonauts on the International Space Station take pictures of Earth out their windows nearly every day, and over a year that adds up to thousands of photos. The people at the Earth Science and Remote Sensing Unit at NASA’s Johnson Space Center in Houston had the enviable job of going through this year’s crop to pick their top 17 photos of Earth for 2017—here’s what they chose!

NASA's Parker Solar Probe and its United Launch Alliance Delta IV Heavy launch vehicle prepare for an unprecedented mission to "kiss the Sun."

101955 Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and since late 2018, the place that NASA’s OSIRIS-REx mission has called home. When OSIRIS-REx arrived on Dec. 3, 2018, it began wrapping Bennu in a complex web of observations. OSIRIS-REx departs Bennu on May 10, 2021, on a return voyage to Earth, bringing with it over 60 grams of sample collected from the asteroid. This narrated video presents the mission’s complete trajectory during its time at Bennu. More: https://nasa.gov/osiris-rex

Take a virtual tour of the Moon in all-new 4K resolution, thanks to data provided by NASA's Lunar Reconnaissance Orbiter spacecraft. As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.

While Apollo placed the first steps on the Moon, Artemis opens the door for humanity to sustainably work and live on another world for the first time. Using the lunar surface as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars. ✨ We are returning to the Moon – to stay – and this is how we are going! Actress Kelly Marie Tran of “Star Wars: The Rise of Skywalker” lent her voice to this project.

This video uses data gathered from the Lunar Reconnaissance Orbiter spacecraft to recreate some of the stunning views of the Moon that the Apollo 13 astronauts saw on their perilous journey around the farside in 1970. These visualizations, in 4K resolution, depict many different views of the lunar surface, starting with earthset and sunrise and concluding with the time Apollo 13 reestablished radio contact with Mission Control. Also depicted is the path of the free return trajectory around the Moon, and a continuous view of the Moon throughout that path. All views have been sped up for timing purposes — they are not shown in "real-time."

In this artist’s rendition, we explore a metallic world named Psyche, an asteroid that offers a unique window into the building blocks of planet formation. The NASA Psyche mission launches in 2023 and will arrive at the asteroid Psyche, which orbits the Sun between Mars and Jupiter, in 2026. The spacecraft, also named Psyche, will spend 21 months orbiting the asteroid, mapping it and studying its properties. The mission is led by Principal Investigator Lindy Elkins-Tanton of Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies is providing a high-power solar electric propulsion spacecraft chassis.

This visualization uses a digital 3D model of the Moon built from global elevation maps and image mosaics by NASA's Lunar Reconnaissance Orbiter mission. It was created to accompany a performance of Claude Debussy's Clair de Lune by the National Symphony Orchestra Pops, led by conductor Emil de Cou, at the Kennedy Center for the Performing Arts in Washington, DC, on June 1 and 2, 2018, as part of a celebration of NASA's 60th anniversary. Clair de Lune (moonlight in French) was published in 1905, as the third of four movements in the composer's Suite Bergamasque, and unlike the other parts of this work, Clair is quiet, contemplative, and slightly melancholy, evoking the feeling of a solitary walk through a moonlit garden. The visuals were composed like a nature documentary, with clean cuts and a mostly stationary virtual camera. The viewer follows the Sun throughout a lunar day, seeing sunrises and then sunsets over prominent features on the Moon. The sprawling ray system surrounding Copernicus crater, for example, is revealed beneath receding shadows at sunrise and later slips back into darkness as night encroaches.

Water in space behaves… differently. Surface tension and capillary flow can be harnessed to move fluids in more efficient ways. What looks like fun could actually help us improve systems for moving fluids in microgravity, in things like fuel tanks for space travel.

For Earth Day 2021, we explore the connections of Earth systems and NASA's ability to observe them in a changing world, highlighting the links between dust transport, vegetation, water quality, conservation and human health, the cryosphere, and disasters.

From year to year, the moon never seems to change. Craters and other formations appear to be permanent now, but the moon didn't always look like this. Thanks to NASA's Lunar Reconnaissance Orbiter, we now have a better look at some of the moon's history. Learn more in this video!
