Back-and-forth blinking of this two-image animation shows movement of a sand dune on Mars. The images are part of a study published by Nature on May 9, 2012, reporting movement of Martian sand dunes at about the same flux (volume per time) as movement of dunes... More »
This is a perspective view of the Nili Patera dune field. A HiRISE image has been draped over a digital elevation model of Mars. Colors correspond to the amplitude of the ripple’s displacement extracted by image correlation between two HiRISE observations sepa... More »
This artistically modified image of the local galaxy Arp 220, captured by the Hubble Space Telescope, helps illustrate the Herschel results. The bright core of the galaxy, paired with an overlaid artist’s impression of jets emanating from it, indicate that the... More »
NASA’s Spitzer Space Telescope was able to detect a super Earth’s direct light for the first time using its sensitive heat-seeking infrared vision. Super Earth’s are more massive than Earth but lighter than gas giants like Neptune. As this artist’s concept sho... More »
What do parents want—aside from kids who come home on time and never talk with their mouths full—and why is an economist trying to answer that question? Because, at its heart, economics is all about the process of making choices. And while places like th... More »

This color view of a mineral vein called “Homestake” comes from the panoramic camera (Pancam) on NASA’s Mars Exploration Rover Opportunity. The vein is about the width of a thumb and about 18 inches (45 centimeters) long. Image Credit: NASA/JPL-Caltech/Cornell... More »
There is an old trick for remembering the difference between stalactites and stalagmites in a cave: Stalactites hold tight to the ceiling while stalagmites might one day grow to reach the ceiling. Now, it seems, stalagmites might also fill a hole in our unders... More »
