If it weren’t for the Sun, Jupiter’s Great Red Spot would be a much blander feature on the gas giant, a new study reveals. This stands apart from what most scientists think about why for why the spot looks so colorfu...

Europe's Rosetta spacecraft made contact with its robot craft Philae soon after the lander embarked Wednesday on a solo, seven-hour descent to a comet, ground controllers said. (WATCH LIVE)

During a nail-biting drop onto the surface of a comet, the European Space Agency's Philae spacecraft snapped a stunning photo of its icy target. See the close up view of Comet 67P/Churyumov-Gerasimenko.

NASA's new Orion spacecraft is now at the launch pad for next month's test flight.

The pilot of the Virgin Galactic spaceship that tore apart over the Mojave Desert didn't know his co-pilot had prematurely unlocked its brakes, despite protocol requiring the co-pilot to announce the step.

The European Space Agency has achieved a historic first--landing a washing machine-sized spacecraft on a comet speeding through our solar system at 41,000 mph (66,000 kph). Here are answers to five questions about the sp...

The Philae lander settled atop the “head” of the rubber-duck shaped object despite trouble with systems designed to secure the probe to the comet --

Europe made history Wednesday by placing the first-ever lander on a comet--but the robot failed to anchor itself properly, raising concerns at ground control.

Sometimes first impressions are poor ones. When the Voyager 2 spacecraft whizzed by Uranus in 1986, the close-up view of the gas giant revealed what appeared to a be a relatively featureless ball. By that point, scientis...

NASA's Goddard Space Flight Center: The present and future of Arctic sea ice studies are focused on not just its declining extent but also its thinning.

Investigators have talked to the pilot who survived the tragic crash of Virgin Galactic's SpaceShipTwo last month, and say that he didn't know that his copilot unlocked the space plane's re-entry system early.

NASA on Wednesday hailed the first-ever landing of a spacecraft on a comet as a "breakthrough moment" in the history of space exploration.

Stephen Hawking is one of our greatest living geniuses—his insights into the nature of black holes, space and time have truly revolutionized physics. --

As the end of its eight-year adventure at Venus edges ever closer, ESA scientists have been taking a calculated risk with the Venus Express spacecraft in order to carry out unique observations of the planet's rarefied ou...

The normally bland face of Uranus has become increasingly stormy, with enormous cloud systems so bright that for the first time ever, amateur astronomers are able to see details in the planet's hazy blue-green atmosphere...

Nearly forty years ago, Guy Consolmagno was young graduate student at the University of Arizona's Department of Planetary Sciences; his work there with the late Michael Drake first proposed that asteroid Vesta was the pa...

We've come a long way since NASA's Mariner 4  --

The image shows comet 67P/CG acquired by the ROLIS instrument on the Philae lander during descent on Nov 12, 2014 14:38:41 UT from a distance of approximately 3 km from the surface....

NASA's first space-bound Orion capsule has arrived at the launch pad, where it will lift off on an uncrewed test flight in support of the space agency's plans for future astronaut missions beyond Earth orbit.

A European probe Wednesday made the first-ever landing on a comet in a quest to explore the origins of the Solar System, but there were concerns over whether it was fastened securely enough to carry out its mission.
