Super-Earth unlikely able to transfer life to other planets
While scientists believe conditions suitable for life might exist on the so-called "super-Earth" in the Gliese 581 system, it's unlikely to be transferred to other planets within that solar system.
Habitable zone super Jupiter-sized exoplanet found in Milky Way bulge
Study shows oceans vital for possibility for alien life
Researchers at the University of East Anglia have made an important step in the race to discover whether other planets could develop and sustain life.
Planets with oddball orbits like Mercury could host life
Mercury has an oddball orbit—it takes longer for it to rotate on its axis and complete a day than it takes to orbit the sun and complete a year. Now, researchers suggest photosynthesis could take place ...
Kepler Space Telescope Discovers its First Five Exoplanets
(PhysOrg.com) -- NASA's Kepler space telescope, designed to find Earth-size planets in the habitable zone of sun-like stars, has discovered its first five new exoplanets, or planets beyond our solar system. ...
Under the bright lights of an aging sun
Life as we know it on Earth is linked to our star, the Sun, which provides our planet with just the right amount of heat and energy for liquid water to be stable in our lakes, rivers and oceans. However, ...
Earth-sized planets in habitable zones are more common than previously thought
The number of potentially habitable planets is greater than previously thought, according to a new analysis by a Penn State researcher, and some of those planets are likely lurking around nearby stars.
Has Kepler found ideal SETI-target planets?
NASA's Kepler mission has discovered a new planetary system that is home to five small planets around a slightly smaller star than our Sun. Two of them are super-Earth planets, most likely made of rock or ice ...
Faith helped steer astronomy professor who made planet discovery
It was a Friday afternoon, Aug. 31 of last year, that Eric Agol, a 42-year-old associate professor of astronomy at the University of Washington, looked at his computer screen and saw something astounding.
Planetary 'runaway greenhouse' more easily triggered, research shows
(Phys.org) —It might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable "runaway greenhouse" stage, according to new research by astronomers at the University of Washington and ...
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 ...
Team predicts satellite could locate hundreds of Earth-sized planets
(PhysOrg.com) -- The race to find exoplanets -- planets outside our solar system -- continues to quicken. Last week NASA researchers announced that the agency’s new space telescope, Kepler, has discovered ...
Extending the habitable zone for red dwarf stars
Scientists have long thought that planets had to orbit very close to small and dim red dwarf stars in order to be warm enough for life. New research challenges that assumption.
Was Venus once a habitable planet?
(PhysOrg.com) -- ESA's Venus Express is helping planetary scientists investigate whether Venus once had oceans. If it did, it may even have begun its existence as a habitable planet similar to Earth.
