Visible image of California’s Rim Fire acquired Aug. 23, 2013 by the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA’s Terra spacecraft, showing extensive, brownish smoke. The imaged area measures 236 by 215 miles (380 by 346 kilometers). Image... More »
This mosaic of images from the Navigation Camera (Navcam) on NASA’s Mars rover Curiosity shows the scene from the rover’s position on the 376th Martian day, or sol, of the mission (Aug. 27, 2013). The images were taken right after Curiosity completed the first... More »

This artist’s concept shows the Wide-field Infrared Survey Explorer, or WISE spacecraft, in its orbit around Earth. In September of 2013, engineers will attempt to bring the mission out of hibernation to hunt for more asteroids and comets in a project called N... More »
People around the world shared more than 1,400 images of themselves as part of the Wave at Saturn event organized by NASA’s Cassini mission on July 19 — the day the Cassini spacecraft turned back toward Earth to take our picture. The mission has assembled a co... More »
Pasadena’s Jet Propulsion Laboratory has launched a four-minute video which features “Sammy the Second,” an animated character demonstrating how NASA’s Space Atomic Clock project is being used in deep-space navigation. Sammy the Second was introduced in the vi... More »
The human body is full of tiny microorganisms—hundreds to thousands of species of bacteria collectively called the microbiome, which are believed to contribute to a healthy existence. The gastrointestinal (GI) tract—and the colon in particular—is home to... More »
Changes in Australia’s mass as reported by data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites from June 2010 to February 2011. Areas in greens and blues depict the greatest increases in mass, caused by excessive precipitation. The cont... More »
This illustration provides a comparison for how big the moons of Mars appear to be, as seen from the surface of Mars, in relation to the size that Earth’s moon appears to be when seen from the surface of Earth. Earth’s moon actually has a diameter more than 10... More »
Radar images of asteroid 2005 WK4 were obtained on Aug. 8, 2013. The asteroid is between 660 – 980 feet (200 – 300 meters) in diameter. Image credit: NASA/JPL-Caltech/GSSR A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientis... More »
This artist’s concept shows NASA’s Voyager spacecraft against a field of stars in the darkness of space. The two Voyager spacecraft are traveling farther and farther away from Earth, on a journey to interstellar space, and will eventually circle around the cen... More »
This view from NASA’s Mars Exploration Rover Opportunity shows an area where a pale-toned geological unit called the “Burns Foundation,” in the foreground, abuts a different geological unit. The darker unit, believed to be older, marks the edge of “Solander Po... More »
