Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.
Researchers using NASA's Spitzer Space Telescope to study developing stars have had a hard time figuring out why the stars give off more infrared light than expected. The planet-forming disks that circle the young stars are heated by starlight and glow with infrared light, but Spitzer detected additional infrared light coming from an unknown source.
Five years ago today, on March 6, 2009, NASA's Kepler Space Telescope rocketed into the night skies above Cape Canaveral Air Force Station in Florida to find planets around other stars, called exoplanets, in search of potentially habitable worlds.
Since then, Kepler has unveiled a whole new side of our galaxy -- one that is teeming with planets. Because of Kepler we now know that most stars have planets, Earth-sized planets are common, and planets quite unlike those in our solar syste...
In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the giant magnetic bubble around Earth, the magnetosphere helps keep it at bay. The parameters, however, change: The particles streaming in could be from the constant solar wind, or perhaps from a giant cloud erupting off the sun called a coronal mass ejection, or CME. Sometimes the configuration is such that the magnetosphere blocks almost all the material, other t...

ATK (NYSE: ATK) will display small satellite products and capabilities including in-orbit life extension services at the Satellite 2014 Conference and Exhibition March 10-13, 2014 in Washington, D.C. ATK will be located at Booth 3087 in the exhibit hall at the Walter E. Washington Convention Center.
Visitors to the ATK exhibit will learn more about these innovative technologies through videos, animation and product model displays. ATK subject matter experts will be available to answer que...
The Orion spacecraft has moved another step closer toward its first test flight as the core and starboard boosters for the United Launch Alliance (ULA) Delta IV Heavy rocket contracted by Lockheed Martin [NYSE: LMT] for that flight have arrived to Cape Canaveral Air Force Station. The rocket will undergo testing and processing at ULA’s Horizontal Integration Facility to prepare for Orion’s Exploration Flight Test-1 later this year.
Technicians offloaded the boosters from a spe...
NASA astronaut Scott Kelly will spend a year aboard ISS, giving researchers a better understanding of how spaceflight effects in the human body. Scott's identical twin Mark (fmr. Space Shuttle cmdr.) provides a unique Earth-based comparison.
Carl Sagan brought science into homes around the United States with his TV shows and books for years. When the famed astronomer died in 1996, he left a legacy of people that were inspired by his unique brand of science education.
One of four business jets converted to train NASA astronauts to land the space shuttle is on final approach to the Alabama home of Space Camp, pending the result of the U.S. Space & Rocket Center's first crowd-funding campaign.
Famous astronomer Carl Sagan brought the wonders of the universe to people living on the planet he dubbed the "pale blue dot." Although Sagan died in 1996 of a rare bone-marrow disease when he was 62, his influence on the public still lives on today.
A new study indicates that the entry, descent and landing of SpaceX's unmanned Dragon capsule at Mars is viable. Moreover, the capsule's descent technique would help set the stage for future human missions to the Red Planet.
Einstein's Theory of Relativity predicts that a mass of star cluster Abell 2744 warps the fabric of space around it, bending and magnifying passing starlight. The Hubble Space Telescope's exposure of the cluster reveals 3,000 magnified galaxies.
An enormous belt of carbon monoxide gas lies in the disk of debris surrounding Beta Pictoris, a young star 63 light-years from Earth. The source of the gas is probably comets, which may have been trapped there by a big alien planet.
In case of an off-course Soyuz landing (and the rescue teams inability to reach the crew in a reasonable time period), astronauts are trained in outdoor winter survival. ESA astronaut Andreas Mogensen looks back at his training.
NASA's historic jumbo jet that ferried retired space shuttles piggyback to their museums is being prepared for its own lift to where it'll be put on public display. The Shuttle Carrier Aircraft is being readied for its final move.
Astronomers studying the dust and gas around bright star Beta Pictoris have discover a cloud of debris from collisions of icy comet-like bodies. It's possible that the comets are trapped in a small region by the gravity of a saturn-sized planet.
