Three-dimensional view of the Martian surface temperature around an idealized boulder at latitude 30°S. On the side opposite to the Sun, temperatures are around -128° Celsius, and as the sun rises, this area heats up rapidly, so frost melts on salt-containing ground before it sublimates into the atmosphere.

A Southwest Research Institute team performed high-resolution, smoothed-particle simulations of a large, differentiated projectile hitting early Mars after its core and mantle had formed. The projectile’s core and mantle particles are indicated by brown and green spheres respectively, showing local concentrations of the projectile materials assimilated into the Martian mantle.

Artist's conception of a massive planet orbiting a cool, young star. In the case of the system discovered by RIT astronomers, the planet is 10 times more massive than Jupiter, and the orbit of the planet around its host star is nearly 600 times that of Earth around the sun.

NASA’s LHASA landslide risk model and Global Landslide Catalog track the areas most at risk from deadly landslides, which can cause effects ranging from destroying towns to cutting off drinking water and transportation networks.

Arctic sea ice was photographed in 2011 during NASA's ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," a shipborne investigation to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems. The bulk of the research took place in the Beaufort and Chukchi seas in summer 2010 and 2011.
