Scientists analyzing the reams of data from NASA's Cassini orbiter at Saturn have discovered 101 geysers erupting from the intriguing icy moon Enceladus and that the spewing material of liquid water likely originates fro...

The European Space Agency's fifth Automated Transfer Vehicle (ATV-5) blasted off from French Guiana Tuesday evening (July 29), kicking off the final mission for this line of unmanned spacecraft, which has been resupplyin...

The shape of the moon deviates from a simple sphere in a way that scientists have struggled to explain. But new research shows that tidal forces during the moon's early history can explain most of its large-scale topogra...

Spaceflight Inc. is getting into the small-satellite operations business.

NASA Breaking News: NASA has selected proposals for two new instruments that will observe changes in global vegetation from the International Space Station. The sensors will give scientists new ways to see how forests an...

Images taken by a European probe en route to link up with a comet, have revealed a striking feature of the target comet coming into view.

Satellites about the size of a loaf of bread may one day explore space, propelled across the vast expanse by an unfurled sail.

Europe's line of space freighters is going out with a (big) bang. Named "Georges Lemaître" after the Belgian priest and astronomer who proposed what became the Big Bang theory, the European Space Agency's fifth and fina...

It's a well-kept secret that the vacuum of space is not -- technically speaking -- a vacuum. Strong winds generated from supernova explosions push material into the interstellar medium, tainting space with the heavier el...

Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues repo...

Earth and Moon in the Hadean epoch were pummeled by large impacts letting magma flow out. But, at the same time, some parts of Earth's surface could have retained liquid water, allowing pre-biotic compounds to form; perh...

Some of the oddly skewed orbits of many alien worlds may be due to the twin stars they are often found circling, a new study suggests.

Cosmic bombardment of the early Earth repeatedly covered the planet's surface with molten rock during its earliest days, but still may have left oases of water that could have supported the evolution of life, scientists ...

The binary system HK Tauri's 'wildly misaligned' discs of dust and gas may help explain why some exoplanets have eccentric orbits around their Suns. The Atacama Large Millimeter/submillimeter Array (ALMA) imaged the syst...

Tidal forces exerted during the solar system's youth can explain most of the moon's large-scale topography, including its slight lemon shape, reports the study, which was published online today (July 30) in the journal N...

Sen. James Inhofe (R-Okla.) is more than just a global warming denier. He's a conspiracy theorist (calling warming a "hoax") and, shockingly, hugely funded by the oil industry. Reading things he's said about global warmi...

The shape of the moon deviates from a simple sphere in ways that scientists have struggled to explain. A new study by researchers at UC Santa Cruz shows that most of the moon's overall shape can be explained by taking in...

Unlike our solitary Sun, most stars form in binary pairs--two stars that orbit a common center of mass. Though remarkably plentiful, binaries pose a number of questions, including how and where planets form in such compl...

ESO Top News: Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas discs around the two young stars in the binary system HK Tauri. These new ALMA obser...

Questions remain as to the eventual place in the new company of Finmeccanica, which is widely expected to purchase a majority stake in Avio SpA to give Finmeccanica the heft it needs to be a third pillar in the joint ven...
