A U.S. review of an updated Chinese-Russian treaty proposal to ban weapons in space finds that it suffers from the same problems that made the original version unacceptable, an American diplomat said.

Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be pro...

On Sept. 10, 2014, the sun unleashed a massive X1.6-class solar flare aimed directly at Earth. Take a look at amazing photos of the solar storm and its effects on Earth in this Space.com gallery.

A pair of NASA officials said the mission team has a solid science plan that will ensure a good return on the $2.5 billion Curiosity rover that has been exploring the red planet the past two years.

NASA's Jet Propulsion Laboratory News and Features: NASA's Mars Curiosity rover has reached Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission's long-term prime destina...

Scientists may have solved the mystery behind why giant hot Jupiter planets have such weird orbits. As these giant worlds drew close to their stars, they may force the stars into a chaotic wobble.

Blame the "hot Jupiters." These large, gaseous exoplanets (planets outside our solar system) can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according...

The five instruments slated to be installed by 2018 will make a total of seven aboard station, which already hosts two.
