An international cadre of scientists using datafrom NASA’s Kepler spacecraft has detected stellar oscillations, or “starquakes,” that yield new insights about the size, age and evolution of stars. The results were presented at a news conference at Aarhus University in Denmark by scientists representing the Kepler Asteroseismic Science Consortium. The … Continue reading
Wispy clouds are illuminated by a bright quarter moon behind the tail of NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, flying observatory during telescope characterization testing in 2008. SOFIA will complement the Hubble, Spitzer, Herschel and James Webb space telescopes and major Earth-based telescopes. The mission, a joint program … Continue reading
Scientists returned this week to the Southern Hemisphere where NASA’s Operation IceBridge mission is set to begin its second year of airborne surveys over Antarctica. The mission monitors the region’s changing sea ice, ice sheets and glaciers. Researchers will make flights from Punta Arenas, Chile, on NASA’s DC-8, a 157-foot … Continue reading
A newly installed webcam is giving the public an opportunity to watch technicians assemble and test the next NASA Mars rover, one of the most technologically challenging interplanetary missions ever designed. NASA’s Mars Science Laboratory, also known as the Curiosity rover, is in a clean room at the agency’s Jet … Continue reading
It has flown to space more than any other craft, and it has carried more crew members to orbit. It was the first spacecraft to retrieve a satellite and bring it back to Earth. It has visited two space stations. It launched a telescope that has seen deeper in space … Continue reading
Taking a long-weekend road trip, NASA’s Cassini spacecraft successfully glided near nine Saturnian moons, sending back a stream of raw images as mementos of its adrenaline-fueled expedition. The spacecraft sent back particularly intriguing images of the moons Dione and Rhea. The Dione and Rhea pictures are the highest-resolution views yet … Continue reading
On October 18, 2010, Typhoon Megi approached and made landfall in the northeastern Isabela Province of the Philippines. Spanning more than 600 kilometers (370 miles) across, Megi was the 15th tropical storm and 7th typhoon of the season in the western Pacific Ocean. It was the most intense tropical cyclone … Continue reading
