Some habitable exoplanets could experience wildly unpredictable climates
Mar 16, 2015 (SPX)
As telescopes of ever-greater power scan the cosmos looking for life, knowing where to look - and where not to waste time looking - will be of great value. New ...
'Habitable' planet GJ 581d previously dismissed as noise probably does exist
Mar 10, 2015 (SPX)
The planet candidate was spotted using a spectrometer which measures the 'wobble', small changes in the wavelength of light emitted by a star, caused as a plane...
Scientists: Nearby Earth-like planet isn't just 'noise'
Mar 07, 2015 (UPI)
Astronomers are having a war of words across the Atlantic over the existence -- or not -- of the first exoplanet ever discovered in a star's habitable zone, the...
Exorings on the Horizon
Mar 05, 2015 (SPX)
Astronomers from the Harvard-Smithsonian Center for Astrophysics and the University of Antioquia (Medellin-Colombia), have devised a novel method for identifyin...
Planet 'Reared' by Four Parent Stars
Mar 05, 2015 (JPL)
Growing up as a planet with more than one parent star has its challenges. Though the planets in our solar system circle just one star - our sun - other more dis...
Planets Can Alter Each Other's Climates over Eons
Feb 26, 2015 (SPX)
A new study sheds light on how exoplanets in tightly-packed solar systems interact with each other gravitationally by affecting one another's climates and their...
The mystery of cosmic oceans and dunes
Feb 20, 2015 (SPX)
Simulations by researchers at Tokyo Institute of Technology and Tsinghua University indicate that Earth-like planets are more likely to be found orbiting Sun-li...
Laser 'ruler' holds promise for hunting exoplanets
Feb 19, 2015 (SPX)
The hunt for Earth-like planets around distant stars could soon become a lot easier thanks to a technique developed by researchers in Germany. In a paper publis...
Scientists predict earth-like planets around most stars
Feb 06, 2015 (SPX)
Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life. The new research, led by ...
Vulcan Planets - Inside-Out Formation of Super-Earths
Feb 04, 2015 (SPX)
NASA's Kepler telescope has discovered many strange, new worlds. None are stranger than the planetary systems that are commonly seen orbiting very close to thei...
Kepler astronomers discover ancient star with 5 Earth-size planets
Jan 29, 2015 (SPX)
Astronomers poring over four years of data from NASA's Kepler spacecraft have discovered a star that's 11.2 billion years old and has at least five Earth-size p...
Smaller Gas Giants Could Support Life
Jan 29, 2015 (SPX)
Two phenomena known to inhibit the potential habitability of planets -- tidal forces and vigorous stellar activity -- might instead help chances for life on cer...
Neptune-like worlds potentially habitable
Jan 29, 2015 (SPX)
Two phenomena known to inhibit the potential habitability of planets -- tidal forces and vigorous stellar activity -- might instead help chances for life on cer...
Dawn ahead!
Jan 29, 2015 (JPL)
NASA's Dawn spacecraft has returned the sharpest images ever seen of the dwarf planet Ceres. The images were taken 147,000 miles (237,000 kilometers) from Ceres...
Habitable Evaporated Cores
Jan 29, 2015 (SPX)
I recently published a paper in Astrobiology that shows that it is possible to form Earth-mass potentially habitable planets from mini-Neptunes that migrate int...
Will NASA's TESS Spacecraft Revolutionize Exoplanet Hunting?
Jan 29, 2015 (SPX)
NASA's Transiting Exoplanet Survey Satellite (TESS), planned to be launched in August 2017 on a SpaceX Falcon 9 rocket from the Cape Canaveral Air Force Station...
Ancient star system has Earth-sized planets forming near start of universe
Jan 28, 2015 (SPX)
A Sun-like star with orbiting planets, dating back to the dawn of the Galaxy, has been discovered by an international team of astronomers. At 11.2 billion years...
Gigantic ring system around J1407b much larger, heavier than Saturn's
Jan 27, 2015 (SPX)
Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the ver...
New research re-creates planet formation in the lab
Jan 26, 2015 (SPX)
New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent ...
Telescope To Seek Dust Where Other Earths May Lie
Jan 21, 2015 (SPX)
The NASA-funded Large Binocular Telescope Interferometer, or LBTI, has completed its first study of dust in the "habitable zone" around a star, opening a new do...
