After spending 4 months aboard the International Space Station, three Expedition 33 crewmembers recently returned to Earth in their Soyuz spacecraft. The spacecraft which made a rare night landing touched down in a remote area of Kazakhstan. (Photo: NASA/Bill Ingalls)

This is a view of Antarctica’s Sheldon Glacier with Mount Barre in the background.  The photo was taken by scientists participating in a new NASA/British Antarctica Survey study that is trying to find out why Antarctic sea ice cover has increased under the effects of climate change over the past two decades.

Scientists will soon conduct experiments to hunt for one of nature's most elusive particles, "dark matter."  An important tool to be used in the experiment is the Large Underground Xenon (LUX) detector.  Here’s a top-down view of the copper photomultiplier tube mounting structure, which is a key component of the detector.  (Photo: Lawrence Livermore National Laboratory)

NASA's Solar Dynamic Observatory (SDO) was snapping pictures of the Sun recently when it erupted with two prominence eruptions, one after the other over a four-hour period.  Fortunately the expanding particle clouds heading into space weren’t directed at Earth.  (Photo: NASA)

This is a view of the country side in Binghamton, NY as seen from inside a US National Weather Service radar radome (which protects radar components from the elements).  The weather radar was recently taken offline so that repairs could be made.  (Photo: NOAA/NWS)

This is Titan, the world’s most powerful and fastest supercomputer located at the Oakridge National Laboratory in Tennessee.  Titan has computational capability is on par with each of the world’s 7 billion people being able to carry out 3 million calculations per second.   (Photo: Oakridge National Laboratory)

Scientists at the U.S. Department of Energy’s (DOE) Ames Laboratory are working to more effectively remove a rare earth element (group of closely related metallic elements) called neodymium from the mix of other materials in a magnet.  Here rare-earth magnet scraps are melted in a furnace with magnesium. (Photo: DOE/Ames Laboratory)
