Iron-rich rocks could could hold signs of life
A robotic mission's search for life on Mars may seem worlds away from human scientists wandering around hot springs in Yellowstone National Park. But a study of the Yellowstone hot springs has revealed new ...
'Cloud' over Mars leaves scientists baffled
Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet.
NASA's Curiosity rover finds fresh signs of ingredients for life on Mars
Mars's life-friendly past just got friendlier. Using samples previously collected by the NASA rover Curiosity, scientists have discovered evidence of nitrates in Martian rock: nitrogen compounds that on Earth ...
Every red dwarf star has at least one planet
Three new planets classified as habitable-zone super-Earths are amongst eight new planets discovered orbiting nearby red dwarf stars by an international team of astronomers from the UK and Chile.
Research suggests Mars once had more water than Earth's Arctic ocean
A primitive ocean on Mars held more water than Earth's Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet's atmosphere.
Newfound planet is Earth-mass but gassy
An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size ...
13 light years away: Earth-like planets are right next door
Using publicly available data from NASA's Kepler space telescope, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that six percent of red dwarf stars have habitable, Earth-sized ...
Kepler finds a very wobbly planet
(Phys.org) —Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting ...
Early Mars may not have been hospitable after all: study
Instead of a warm, wet and possibly life-bearing planet as some scientists contend, early Mars may have been a hostile and volatile place with frequent volcanic outbursts, a study said Sunday.
Exoplanet formation surprise: Evidence of farthest planet forming from its star
A team of researchers has discovered evidence that an extrasolar planet may be forming quite far from its star—- about twice the distance Pluto is from our Sun. The planet lies inside a dusty, gaseous disk ...
Astronomers anticipate 100 billion Earth-like planets
(Phys.org) —Researchers at The University of Auckland have proposed a new method for finding Earth-like planets and they anticipate that the number will be in the order of 100 billion.
Harsh space weather may doom potential life on red-dwarf planets
(Phys.org) —Life in the universe might be even rarer than we thought. Recently, astronomers looking for potentially habitable worlds have targeted red dwarf stars because they are the most common type of ...
Billion-year-old water could hold clues to life on Earth and Mars
A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life.
NASA rover lands on Mars (Update 4)
NASA has successfully landed its $2.5 billion Mars Science Laboratory and Curiosity rover on the surface of the Red Planet, breaking new ground in US-led exploration of an alien world.
