NASA's Curiosity rover has been gathering a wealth of information about winds and natural radiation on Mars, spotting whirlwinds and changes in air pressure.
Not only was there once water on Mars - some of it was warm enough to support life, an analysis of meteorites shows.
Russia has restored full communication with the International Space Station after a cable break cut off not just the ISS but civilian satellites too.
Astronomers have for the first time found a rogue planet that appears to be wandering through space on its own, unattached to any star.
Scientists using BOSS, the Baryon Oscillation Spectroscopic Survey, have used a new mapping technique to probe the period before dark energy began to speed up the expansion of the universe.
Rising levels of carbon dioxide in the atmosphere are leaking out to the edge of space and interfering with satellites, new research shows.
NASA's stalwart Hubble Space Telescope has snapped a beautiful galaxy that, with its reddish and yellow central area, seems rather like an spectacular explosion from a Hollywood movie.
Astronomers have at last discovered a nearby Earth-like planet that could easily have liquid water - and life.
The rate of star formation in the universe is now only one-thirtieth of its peak, says an international team of astronomers - and the decline is set to continue.
Our solar system didn't, as previously thought, take twice as long as most to form, new research shows.
Data from NASA's Curiosity rover is helping to explain how Mars may have lost much of its original atmosphere, leaving it with 100 times less than Earth.
NASA's Hubble Space Telescope recently captured an impressive view of the center of globular cluster NGC 6362.
The size and location of an asteroid belt could be a significant factor in determining whether complex life will evolve on a nearby Earth-like planet.
Astronomers have measured the light from the very earliest stars, working out for the first time the total amount of light from all the stars that have ever shone.
The highly-patterned surface of the giant asteroid Vesta is caused by a long history of strikes from hundreds of other, smaller asteroids.
The ESO’s La Silla Observatory in Chile recently captured a colorful view of the globular star cluster NGC 6362.
NASA's Curiosity rover has finished its first set of tests on the soil sample it scooped up earlier this month and discovered it's a lot like the volcanic soils of Hawaii.
An international team of physicists have proposed anl experiment to challenge conventional theories about the nature of space and time, as well as Einstein's theory of relativity.
Using the Sloan Digital Sky Survey, researchers have discovered a stream of stars believed to be the remnant of an ancient cluster slowly being ingested by our own Milky Way galaxy.
Crazy as it sounds, an MIT scientist is proposing that, if a dangerous asteroid approaches the Earth, it could be deflected by firing paintballs at it.
