Scientists think the moon coalesced out of material blasted into space when a large object slammed into the proto-Earth in the solar system's early days. Determining the composition of Venus could help explain how this m...

This multidimensional shape can simplify certain quantum equations — and possibly also revolutionize physics.

Gliese 581g is an extra-solar planet that was discovered in 2010, but quickly cast into doubt by other studies. The original discoverers then published a follow-up paper in 2012 defending their find.

NASA's Cassini probe has captured the highest resolution video yet of Saturn's odd, hexagon shaped jet stream that spins around the gas giants north pole.

Since the first up-close observations of Saturn, made by the Pioneer 11 probe in 1979, a great deal has been learned about the dynamics of the gas giant's magnetosphere. In-depth observations made by the Cassini orbiter,...

(Phys.org) --A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team...

The Giant Magellan Telescope's third primary mirror will be unveiled at the University of Arizona's Steward Observatory Mirror Lab on December 6, 2013. The combined surface area of the three mirrors created to date surpa...

If you live in the southern hemisphere, the southern sky constellation of Centaurus may look a little different to you tonight, as a bright nova has been identified in the region early this week. (...)Read the rest of A ...

Data from NASA's Chandra X-ray Observatory has revealed faint remnants of a supernova explosion and helped researchers determine Circinus X-1 -- an X-ray binary -- is the youngest of this class of astronomical objects fo...

NASA's Jet Propulsion Laboratory News and Features: Ed Stone, the project scientist for NASA's Voyager mission since 1972, appears on TV with talk show host Stephen Colbert and receives one of NASA's highest honors.

NASA's Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole....

For decades, the space race was seen as being mostly about national pride. Getting there first mattered most, whereas pushing the frontiers of science and technology took a close second.

X-rays streaming toward Earth from the region near a neutron star that is cannibalizing its companion star have revealed the pair to be the youngest "X-ray binary" yet known. The discovery by a team that includes a Penn ...

We present an update and a video about the successful design, construction, and testing in a vacuum chamber by Honeybee Robotics of a prototype PlanetVac system, a new planetary surface sampling technique, sponsored by T...

Just over a year since launch, NASA's Van Allen Probes mission continues to unravel longstanding mysteries of Earth's high-energy radiation belts that encircle our planet and pose hazards to orbiting satellites and astro...

NASA's Chandra X-ray Observatory: A neutron star and normal star binary pair about 26,000 light years away in the Milky Way galaxy.

Voyager 1 sent back 'tones' recorded by a plasma wave instrument showing the change as the craft crossed over from the heliosphere to interstellar space.

Now in orbit around the moon, NASA's newest lunar mission has completed the commissioning phase, and its science instruments have passed their preliminary checks....

NASA's Solar Dynamics Observatory was treated to another lunar transit on Dec 2, 2013. The SDO team compiled the very best views from different imagers onboard the spacecraft.

It's going to be a ball when NASA's Dawn spacecraft finally arrives at the dwarf planet Ceres, and mission managers have now inked in the schedule on Dawn's dance card....

Here's a lovely new view of Dione, one of the lovely mid-sized icy moons of Saturn, assembled by Daniel Macháček.
