Astrophysical Imaging and Experimentation

Images of celestial bodies and phenomena captured through scientific instruments, including radar and X-ray images of comets and the human stomach.

Fluorescent minerals emit visible light when exposed to ultraviolet light

The minerals are lit by ultraviolet light, which coverts a small amount of light into heat, and return the rest as visible light causing them to glow.

The Philae lander of the European Space Agency's Rosetta mission captured this view during its first bounce after hitting the surface of comet 67P/Churyumov-Gerasimenko on Nov. 12, 2014, with blurring as a result of the lander's own motion. The image from

These images were obtained by Cassini's radar instrument during a flyby on Dec. 21, 2008. The radar antenna was pointing toward Titan at an altitude of 970 kilometers (684 miles) during the closest approach.

This image was obtained by NASA's Cassini radar instrument during a flyby on Oct. 28, 2005. Equatorial Pass (Trailing hemisphere, Central Adiri, Central Belet, Huygens Landing Site, Antillia Faculae).

This image, produced from instrument data aboard NASA's Space Shuttle Endeavour, is a stereoscopic view of the topography of Port-au-Prince, Haiti where a magnitude 7.0 earthquake occurred on January 12, 2010. You need 3-D glasses to view this image.

Bright strands in Saturn's ever changing F ring emerge from the planet's shadow. The F ring usually has a single bright core, about 50 kilometers (31 miles) across, but the section of the ring seen here appears to have a second bright strand

This image is from a set of mosaic images from NASA's Cassini spacecraft showing three fan-like structures in Saturn's tenuous F ring. Such fans suggest the existence of additional objects in the F ring.

This image was acquired by NASA's Mars Reconnaissance Orbiter to complete a stereo pair over sinuous ridges in Argyre Planitia, but dust clouds kicked up, obscuring most of the surface.

Saturn's shadow sweeps across the rings in a view captured on Nov. 5, 2006 by NASA's Cassini spacecraft. In the bottom half of the image, the countless icy particles that make up the rings bask in full daylight. In the top half, they move through Saturn's shadow. On the right side of the image, the planet's night side, dimly lit by reflected ringshine, can be seen through gaps in the darkened rings. This view is a mosaic of four visible light images taken with Cassini's narrow-angle camera at a distance of approximately 932,000 miles (1.5 million kilometers) from Saturn. The Cassini spacecraft ended its mission on Sept. 15, 2017.

P-29506BW Range 1.12 million kilometers (690,000 miles) This high-resolution image of the epsilon ring of Uranus is a clear-filter picture from Voyager's narrow-angle camera and has a resolution of about 10 km (6 mi). The epsilon ring, approx. 100 km (60 mi) wide at this location, clearly shows a structural variation. Visible here are a broad, bright outer component about 40 km (25 mi) wide; a darker, middle region of comparable width; and a narrow, bright inner strip about 15 km (9 mi) wide. The epsilon-ring structure seen by Voyager is similiar to that observed from the ground with stellar-occultation techniques. This frame represents the first Voyager image that resolves these features within the epsilon ring. The occasional fuzzy splotches on the outer and innerparts of the ring are artifacts left by the removal of reseau marks (used for making measurements on the image).

Saturn's moon Mimas hangs in the sky above Saturn's rings in this Cassini spacecraft narrow angle camera image from Aug. 3, 2004. Saturn's shadow stretches across the rings at bottom right, while several bright clumps in the F ring orbit the planet. Mimas is 398 kilometers (247 miles) wide. The image was taken in visible light with the narrow angle camera at a distance of 8 million kilometers (5 million miles) from Saturn. The image scale is 48 kilometers (30 miles) per pixel. Contrast was slightly enhanced to aid visibility. http //photojournal.jpl.nasa.gov/catalog/PIA06478

Today's VIS image shows a small portion of Olympia Undae. Olympia Undae is a large dune field that dominates the plains along part of the north polar cap.

This VIS image of Olympia Undae was collected during north polar spring. The crests of the dunes and other surfaces are light colored, indicative of a frost covering. The density of dunes and the alignments of the dune crests varies with location, controlled by the amount of available sand and the predominant winds over time. As the season changes into summertime, the dune crests will lose the frost and reveal the darker sand beneath. Olympia Undae is a vast dune field in the north polar region of Mars. It consists of a broad sand sea or erg that partly rings the north polar cap from about 120° to 240°E longitude and 78° to 83°N latitude. The dune field covers an area of approximately 470,000 km2 (bigger than California, smaller than Texas). Olympia Undae is the largest continuous dune field on Mars. Olympia Undae is not the only dune field near the north polar cap, several other smaller fields exist in the same latitude, but in other ranges of longitude, e.g. Abolos and Siton Undae. B

When seen up close, the F ring of Saturn resolves into multiple dusty strands. NASA's Cassini spacecraft's view shows three bright strands and a very faint fourth strand off to the right.

Saturn's C ring isn't uniformly bright. Instead, about a dozen regions of the ring stand out as noticeably brighter than the rest of the ring, as shown here by NASA's Cassini spacecraft.

This June 2017 stereo scene from NASA's Mars Exploration Rover Opportunity rover shows the area just above Perseverance Valley on the rim of Endeavour Crater. The view combines images from the left eye and right eye of the rover's panoramic camera (Pancam) to appear three-dimensional when seen through blue-red glasses with the red lens on the left. Toward the right side of the scene is a broad notch in the crest of the crater's rim. Opportunity left wheel tracks in that area as it observed Perseverance Valley from above in the spring of 2017. The valley is a major destination for the rover's extended mission. It descends out of sight on the inner slope of the rim, extending down and eastward from that notch. Opportunity's Pancam took the component images for this view from a position outside the crater during the span of June 7 to June 19, 2017, sols 4753 to 4765 of the rover's work on Mars. This scene includes features that might have been ancient channels from water, ice or wind movi

This VIS image shows the eastern flank of Pavonis Mons. The darker streaks are created by wind action. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.

The Water Mist commercial research program is scheduled to fly an investigation on STS-107 in 2002 in the updated Combustion Module (CM-2), a sophisticated combustion chamber plus diagnostic equipment. The Center for the Commercial Applications of Combustion in Space (CCACS), a NASA Commercial Space Center located at the Colorado School of Mines, is investigating the properties of mist fire suppression in microgravity with Industry Partner Environmental Engineering Concepts. These experiments consist of varying water droplet sizes and water mist concentrations applied to flame fronts of different propane/air mixtures. Observations from these tests will provide valuable information on the change of flame speed in the presence of water mist. Shown here is a flame front propagating through the Mist flame tube during 1-g testing at NASA/Glenn Research Center.
