Researchers find tidally distorted exoplanets may have unique signatures
Astronomers could soon be able to find rocky planets stretched out by the gravity of the stars they orbit, according to a group of researchers in the United States. The team, led by Prabal Saxena of George ...
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 ...
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.
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 ...
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 ...
Team uncovers secrets of Mars' birth from unique meteorite
As NASA prepares to launch a new Martian probe, a Florida State University scientist has uncovered what may be the first recognized example of ancient Martian crust.
Researchers find phosphate in more soluble form on Mars
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 ...
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.
Retired star found with planets and debris disc
(Phys.org) —ESA's Herschel space observatory has provided the first images of a dust belt – produced by colliding comets or asteroids – orbiting a subgiant star known to host a planetary system. The ...
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.
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 ...
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.
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.
