A ‘Blue Marble’ image of the Earth taken from the VIIRS instrument aboard NASA’s most recently launched Earth-observing satellite – Suomi NPP. This composite image uses a number of swaths of the Earth’s surface taken on January 4, 2012. The NPP satellite was renamed ‘Suomi NPP’ on January 24, 2012 to honor the late Verner E. Suomi of the University of Wisconsin. Suomi NPP is NASA’s next Earth-observing research satellite. It is the first of a new generation of satellites that will observe many facets of our changing Earth. Suomi NPP is carrying five instruments on board. The biggest and most important instrument is The Visible/Infrared Imager Radiometer Suite or VIIRS. Image Credit: NASA/NOAA/GSFC/Suomi NPP/VIIRS/Norman Kuring

The Multi-Purpose Crew Vehicle (MPCV), or Orion, being assembled and tested at Lockheed Martin’s Vertical Testing Facility in Colorado. Drawing from more than 50 years of spaceflight research and development, Orion is designed to meet the evolving needs of our nation’s space program for decades to come. As the flagship of our nation’s next-generation space fleet, Orion will push the envelope of human spaceflight far beyond low Earth orbit. Orion may resemble its Apollo-era predecessors, but its technology and capability are light years apart. Orion features dozens of technology advancements and innovations that have been incorporated into the spacecraft’s subsystem and component design. A test version of the Orion spacecraft makes a stop at the Science Museum Oklahoma in Oklahoma City today, giving residents the chance to see a full scale test version of the vehicle that will take humans into deep space.

Combining almost opposite ends of the electromagnetic spectrum, this composite of the Herschel in far-infrared and XMM-Newton’s X-ray images shows how the hot young stars detected by the X-ray observations are sculpting and interacting with the surrounding ultra-cool gas and dust, which, at only a few degrees above absolute zero, is the critical material for star formation itself. Both wavelengths would be blocked by Earth’s atmosphere, so are critical to our understanding of the lifecycle of stars Image Credit: ESA/Herschel/PACS/SPIRE/Hill, Motte, HOBYS Key Programme Consortium

A distant super-Earth named "55 Cancri e" is wetter and weirder than astronomers thought possible. The discovery has researchers re-thinking the nature of alien worlds.

Astronomers using data from NASA’s Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.
