This simulated view from NASA’s Cassini spacecraft shows the expected positions of Saturn and Earth on July 19, 2013, around the time Cassini will take Earth’s picture. Cassini will be about 898 million miles (1.44 billion kilometers) away from Earth at the ti... More »
This is a reduced version of panorama from NASA’s Mars rover Curiosity with 1.3 billion pixels in the full-resolution version. It shows Curiosity at the “Rocknest” site where the rover scooped up samples of windblown dust and sand. Curiosity used three cameras... More »
This artist’s concept depicts the moment that NASA’s Curiosity rover touches down onto the Martian surface. The entry, descent, and landing (EDL) phase of the Mars Science Laboratory mission begins when the spacecraft reaches the Martian atmosphere, about 81 m... More »
Artist’s concept of NuSTAR in orbit. NuSTAR has a 33-foot (10-meter) mast that deploys after launch to separate the optics modules (right) from the detectors in the focal plane (left). Image credit: NASA/JPL-Caltech NuSTAR Status Update NuSTAR has been busy ... More »
This photo shows the ice front of Venable Ice Shelf, West Antarctica, in October 2008. It is an example of a small-size ice shelf that is a large melt water producer. The image was taken onboard the Chilean Navy P3 aircraft during the NASA/Centro de Estudios C... More »
This graphic depicts the Mars Climate Sounder instrument on NASA’s Mars Reconnaissance Orbiter measuring the temperature of a cross section of the Martian atmosphere as the orbiter passes above the south polar region. Researchers using NASA’s Mars Reconnaissan... More »
Several types of downhill flow features have been observed on Mars. This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter is an example of a type called “linear gullies.” Image credit: NASA/JPL-Cal... More »
This illustration shows a newfound reservoir of stellar fuel discovered by the Herschel space observatory (red). Image credit: ESA/NASA/JPL-Caltech Newly formed stars shine brightly, practically crying out, “Hey, look at me!” But not everything in our Milky Wa... More »
The Sculptor galaxy is seen in a new light, in this composite image from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Southern Observatory in Chile. Image credit: NASA/JPL-Caltech/JHU › NuSTAR view only Nearly a decade ago, NASA’s ... More »
Permafrost zones occupy nearly a quarter of the exposed land area of the Northern Hemisphere. NASA’s Carbon in Arctic Reservoirs Vulnerability Experiment is probing deep into the frozen lands above the Arctic Circle in Alaska to measure emissions of the greenh... More »
This illustration shows the path of the small asteroid 2013 LR6, which will safely pass within 65,000 miles (105,000 kilometers) of Earth on June 7 at 9:42 p.m. PDT (June 8 at 12:42 a.m. EDT). Image credit: NASA/JPL-Caltech. Small asteroid 2013 LR6 will safely... More »
Researchers for the first time mapped the extent and frequency of understory fires across a study area (green) spanning 1.2 million square miles (3 million square kilometers) in the southern Amazon forest. Fires were widespread across the forest frontier durin... More »
