The six people who are selected to participate in the Mars Society's project will spend an entire year at a station located 900 miles from the North Pole.
To celebrate 10 years of images from the European Space Agency's Mars Express orbiter, the German Aerospace Center has compiled a video that gives sweeping digital views of the planet's landscape.
Two new studies agree that Kepler-78b is about the same size and composition as Earth, but because it orbits its star at one-tenth the distance of our orbit, it's way too hot to support life.
Found by the Hubble Space Telescope, it's the farthest galaxy located to date, and is giving astronomers one of the earliest glimpses of what the universe was like after the Big Bang.
Now that a prototype of a crew capsule has been built and is ready for testing, it's still not clear how the US' next manned spacecraft will be used.
In a few months, World View will offer tickets for balloon rides that will take passengers to an altitude of about 100,000 feet. It's not high enough to experience microgravity, but they promise an awesome view.
A pending launch has supporters excited about a possible Asian space race and opponents concerned about more pressing needs here on Earth.
A network of probes that communicate with each other using the power of the stars isn't within the reach of current technology, but it could be someday, according to a new paper.
Scientists say they've located the first definitive proof of a comet hitting Earth: a diamond-studded pebble they've named after legendary female philosopher-scientist Hypatia of Alexandria.
Originally given a 1-in-300 chance of hitting Earth -- 50 percent higher than the average for all other near-Earth objects located to date -- 1950 DA has had its odds reassessed. Fortunately it's not expected to arrive for another 866 years.
NASA's Cassini spacecraft has detected propylene, a chemical used to create food storage containers and other plastic items, on Saturn's largest moon. It's the first time this chemical has been found anywhere outside of Earth.
Capturing a smaller space object that temporarily enters Earth's orbit could be a lot easier and cheaper while still providing valuable data, say proponents.
Using data from space telescopes, including the now-sidelined Kepler, astronomers have identified cloud structures on Kepler-7b, a "hot Jupiter" exoplanet that was one of the first discovered.
Analysis of the first scoop of topsoil picked up by NASA's Curiosity rover reveals a composition that includes two percent water. It could mean one less worry for future human visitors.
Thanks to the efforts of over 83,000 volunteer citizen scientists around the world participating in the Galaxy Zoo 2 project, the latest catalog of galaxy data is 10 times larger than any previous catalog of its kind.
