Graphene only as strong as weakest link: Rice, Georgia Tech experiments determine real-world limits of two-dimensional carbon
An electron microscope image shows a pre-crack in a suspended sheet of graphene used to measure the overall strength of the sheet in a test at Rice University. Rice and Georgia Tech scientists performed experiments and theoretical calculations and found that graphene, largely touted for its superior physical strength, is only as strong as its weakest point.

Target on Mars Looks Good for NASA Rover Drilling
This two-step animation shows before and after views of a patch of sandstone scrubbed with the Dust Removal Tool, a wire-bristle brush, on NASA's Curiosity Mars rover. Both images were taken April 26, 2014, by the Mars Hand Lens Imager on Curiosity's arm. The target rock is called "Windjana."

NASA Seeks External Concepts for Mission to Oceanic Jovian Moon
This image shows two views of the trailing hemisphere of Jupiter's ice-covered satellite, Europa. The left image shows the approximate natural color appearance of Europa. The image on the right is a false-color composite version combining violet, green and infrared images to enhance color differences in the predominantly water-ice crust of Europa.

NASA Puzzles Out Ozone's Ups and Downs
Astronauts aboard the International Space Station captured this photograph of Earth's atmospheric layers on July 31, 2011, revealing the troposphere (orange-red) to the stratosphere and above. Earth-observing instruments in space allow scientists to better understand the chemistry and dynamics occurring within and between these layers.

NASA's Spitzer and WISE Telescopes Find Close, Cold Neighbor of Sun
This artist's conception shows the object named WISE J085510.83-071442.5, the coldest known brown dwarf. This cool star-like body is as frosty as the North Pole (or between minus 54 and 9 degrees Fahrenheit). It is also the fourth closest system to our sun, at 7.2 light-years from Earth.
