The bright landing platform left behind by NASA's Mars Exploration Rover Opportunity in 2004 is visible inside Eagle Crater, at upper right in this April 8, 2017, observation by NASA's Mars Reconnaissance Orbit More
NASA's Dawn spacecraft took this picture as it reached its new orbit to observe Ceres in opposition, when Dawn is directly between the sun and the Occator Crater bright spots. Entering the very tight opposition More
An active region that had just rotated into view blasted out a coronal mass ejection, which was immediately followed by a bright series of post-coronal loops seeking to reorganize that region's magnetic field ( More
The low angle of the sun over Tethys' massive canyon, Ithaca Chasma (near the terminator, at right), highlights the contours of this enormous rift. Ithaca Chasma is up to 60 miles (100 kilometers) wide, and ru More
The THEMIS 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 eas More
Gullies eroded into the steep inner slope of an impact crater at this location appear perfectly pristine in this image captured by NASA's Mars Reconnaissance Orbiter (MRO). Although at first glance it may appea More
Dark, windblown sand covers intricate sedimentary rock layers in this image captured by NASA's Mars Reconnaissance Orbiter (MRO) from Ganges Chasma, a canyon in the Valles Marineris system. These features are More
This artist's concept shows OGLE-2016-BLG-1195Lb, a planet discovered through a technique called microlensing. The planet was reported in a 2017 study in the Astrophysical Journal Letters. Study authors used th More
Although Mars is known for having the largest volcano in our solar system, Olympus Mons, we also find small-scale volcanic features on its surface, as shown in this image from HiRISE onboard NASA's Mars Reconna More
This observation from NASA's Mars Reconnaissance Orbiter (MRO) is an oblique view of gully deposits from the steep slope of an impact crater. The deposits with anomalous (bluish) colors may reveal very recent More
The THEMIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. hese false color images may reveal subtle variations of the surface not easi More
In the high plains of the Andes in Bolivia, Lake Poopo has virtually vanished, as shown in this image from NASA Terra spacecraft. Once covering over 3,000 square kilometers, the lake essentially dried up in 201 More
In the north, Enceladus' surface appears to be about as old as any in the solar system. The south, however, is an entirely different story. The north polar area of Enceladus (313 miles or 504 kilometers across More
Mamers Valles is a long sinuous canyon beginning in Arabia Terra and ending in the Northern lowlands of Deuteronilus Mensae. This image from NASA Mars Reconnaissance Orbiter features the southern facing slope o More
The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches rising up above them Apr. 24-26, 2017, as seen by NASA Solar Dynamics Observatory. The connection between oppos More
The sounds and spectrograms in these two videos represent data collected by the Radio and Plasma Wave Science, or RPWS, instrument on NASA's Cassini spacecraft, as it crossed the plane of Saturn's rings on two More
Ceres surface shows evidence for different types of flows that indicate the presence of ice in the regolith. One type of flow encircles the large impact crater at right in this image taken by NASA Dawn spacecra More
Although large gullies (ravines) are concentrated at higher latitudes, there are gullies on steep slopes in equatorial regions, as seen in this image captured by NASA's Mars Reconnaissance Orbiter (MRO). The c More
The THEMIS 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 ea More
This image captured by NASA Mars Reconnaissance Orbiter MRO covers diverse surface units on the floor of eastern Coprates Chasma in eastern Valles Marineris. The bedrock has diverse minerals producing wonderful More
This artist's rendering shows the twin spacecraft of the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, a partnership between NASA and the German Research Centre for Geosciences (GFZ). GR More
Recurring slope lineae (RSL) are seasonal flows on warm slopes, and are especially common in central and eastern Valles Marineris, as seen in this observation by NASA's Mars Reconnaissance Orbiter (MRO). This i More
This 360-degree mosaic from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover looks out over a portion of the Bagnold Dunes, which stretch for several miles. From early February to early April 2017, the More
This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows two scales of ripples, plus other textures, in an area where the mission examined a linear-shaped dune in the Bagnold dune field on More
Team Vandenberg successfully launched a Falcon 9 rocket carrying both Iridium and Grace FO payloads from Space Launch Complex-4 here, Tuesday, May 22, at 12:47 p.m. PDT. (U.S. Air Force photo by Senior Airman C More
