NASA technologies are being used to locate underground water in some of the driest places on the Earth, build quieter and more fuel-efficient airplanes, and create shock absorbers that brace buildings in earthquakes.

NASA has contributed two Earth science instruments for NOAA’s space weather observing satellite called the Deep Space Climate Observatory or DSCOVR, set to launch in January 2015. One of the instruments called EPIC or Earth Polychromatic Imaging Camera will image the Earth in one picture, something that hasn’t been done before from a satellite. EPIC will also provide valuable atmospheric data.

NASA has exercised the second option of its Information Technology and Multimedia Services (ITAMS) contract with DB Consulting Group, Inc., Silver Spring, Maryland, to provide information technology, multimedia, information management and external relations support services at the agency’s Johnson Space Center in Houston.

Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th century for reasons scientists still don’t understand.

A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study estimates that tropical forests absorb 1.4 billion metric tons of carbon dioxide out of a total global absorption of 2.5 billion -- more than is absorbed by forests in Canada, Siberia and other northern regions, called boreal forests.

At a time when our earliest human ancestors mastered walking upright the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour.

Astronomers have observed the largest X-ray flare ever detected from the supermassive black hole at the center of the Milky Way galaxy.

The object, a printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with NASA to design, build and test the 3-D printer.

NASA’s planet-hunting Kepler spacecraft makes a comeback with the discovery of the first exoplanet found using its new mission -- K2

The closest planet to the sun appears to get hit by a periodic meteor shower, possibly associated with a comet that produces multiple events annually on Earth.
