Settling on Mars isn't going to be easy, though plans are moving forward. Now, scientists have created an innovative new technique that may allow Martian colonists to harvest energy from carbon dioxide.
NASA's Hubble Space Telescope has spotted a distant supernova split into four images for the very first time. The multiple images of the exploding star are due to the powerful gravity of a foreground elliptical galaxy embedded in a massive cluster of galaxies.
It turns out that Mars may have held more water than Earth's Arctic Ocean and covered a great portion of the planet's surface than the Atlantic. Scientists have found that the Red Planet was once watery, and that it lost its ocean over time.
While some galaxies are veritable star nurseries, others went barren years ago. Yet what causes some galaxies to produce new stars while others go silent? That's a good question and now, astronomers may have found the answer.
Most planets have just one or two stars to contend with. Now, though, astronomers have discovered a planet that had four parent stars. Scientists have recently uncovered two exoplanets, one which has three parent stars and another which has four.
Scientists may have gotten a better glimpse of weather on other planets. They've created a new technique that analyzes data from NASA's Kepler space observatory to determine the types of clouds on planets that orbit other stars.
NASA's Dawn spacecraft is approaching its historical rendezvous with the dwarf planet Ceres. Now, it's returned new images captured on its approach, revealing new features of the dwarf planet.
Astronomers have made a somewhat unusual finding. They've found a galaxy that looks old, but exists in a young universe. The findings reveal a bit more about galaxy formation and tell them a bit more about the early universe.
NASA's Wide-field Infrared Survey Explorer (WISE) has spotted a stellar nursery that's essentially in the middle of nowhere. The cluster of stars is forming at the very edge of the Milky Way galaxy.
Saturn's moon, Titan, may just support life like we've never seen before. Scientists have found that it may be possible that a new type of methane-based, oxygen-free life form that can metabolize similar to life on Earth could exist on the moon.
NASA's Curiosity rover has detected an episodic increase in the concentration of methane in Mars' atmosphere.
