Uranus' magnetosphere, the region defined by the planet's magnetic field and the material trapped inside it, gets flipped on and off like a light switch every day as it rotates along with the planet, scientists have discovered. It's 'open' in one orientation, allowing solar wind to flow into the magnetosphere; it later closes, forming a shield against the solar wind and deflecting it away from the planet.
A research group has found a long-sought explanation for the apparent contradictions implicit in the composition of lunar and Martian meteorites. They were able to demonstrate how meteorites could contain within narrow spaces minerals whose formation conditions are quite different. These findings provide new impetus for meteorite research.
The plane of the solar system is warped in the belt's outer reaches, signaling the presence of an unknown Mars-to-Earth-mass planetary object far beyond Pluto, according to new research.
Research deciphering the hidden magnetic messages encoded in a rare group of meteorites has helped secure nearly half a billion dollars of NASA funding for a journey to their parent asteroid -- the only known place in the solar system where scientists can examine directly what is probably a metallic core.
A new approach to scientific exploration has been revealed by researchers, which they call exploration telepresence.
How do we prevent astronauts in space from inhaling hazardous gases? A hi-tech optical gas sensor provides a solution.
NASA's Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star's habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet.
An international team of scientists recently discovered the role that hot electrons may play in the waves and fluctuations detected by satellites. The results are based on data collected by the Van Allen Probes, twin robotic spacecraft launched by NASA in 2012 to help scientists better understand these belt regions.
An astrophysicists has warned that an asteroid strike is just a matter of time.
Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.
Researchers have been trying to find out how the plasma flow is influenced by its environment via laboratory experiments. And in doing so, have made headway on research towards creating an electrodeless plasma thruster used to propel spacecraft.
Scientists report the successful transmission of entangled photons between suborbital space and Earth.
Astronomers have created the largest image ever of the dense band of star-forming gas that weaves its way through the northern portion of the Orion Nebula.
Though astronomers have long known that many if not most stars are binaries, the question has always been, Were they born that way, or did one star capture another? Astronomers teamed up to systematically study very young stars inside their nest eggs, called dense cores, in the Perseus molecular cloud and concluded that all sunlike stars are born as wide binaries. Most subsequently split up, while the rest become tight binaries.
A team of astronomers seeks to change the way scientists approach the search for Earth-like planets orbiting stars other than the sun. They favor taking a statistical comparative approach in seeking habitable planets and life beyond the solar system.
NASA's Human Research Program (HRP) is simulating space radiation on Earth following upgrades to the NASA Space Radiation Laboratory (NSRL) at the US Department of Energy's Brookhaven National Laboratory. These upgrades help researchers on Earth learn more about the effects of ionizing space radiation to keep astronauts safe on a journey to Mars.
Jupiter is the oldest planet in our solar system, an international group of scientists has found.
Astronomers have determined how the enigmatic gas flow from a massive baby star is launched. The team used ALMA to observe the baby star and obtained clear evidence of rotation in the outflow. The motion and the shape of the outflow indicate that the interplay of centrifugal and magnetic forces in a disk surrounding the star plays a crucial role in the star's birth cry.
SpaceX is scheduled to launch its Dragon spacecraft for its eleventh commercial resupply mission to the International Space Station June 1 from NASA's Kennedy Space Center's historic pad 39A.
This seemingly unspectacular series of dots with varying distances between them actually shows the slow waltz of two brown dwarfs. The image is a stack of 12 images made over the course of three years with the NASA/ESA Hubble Space Telescope. Using high-precision astrometry, astronomers tracked the two components of the system as they moved both across the sky and around each other.
