Latest Gliese 581 Stories
Astronomers just can't decide on whether GJ 581d, a super-Earth planet, is real or if it is just 'noise.'
Gliese 581g, described as one of the most Earth-like planets when it was originally discovered four years ago, probably does not exist, researchers from Penn State University and the University of Texas at Austin report in the latest edition of the journal Science.
A new paper published in the journal Planetary and Space Science claims planets that were once thought uninhabitable may actually be able to contain life after all.
The search for extra-terrestrial planets has been ongoing for at least the past 21 years. Since the early days of exoplanet hunting, the number of such planets identified by scientists has pushed beyond a thousand, thanks largely to the advent of high-tech space observatories, such as the Kepler Space Telescope.
Astronomers have discovered a record-breaking planetary system with at least six planets orbiting its host star, of which three are super-earths and lie within the habitable zone.
Good news! The ESO’s HARPS telescope team has found a potentially habitable planet around the red dwarf star Gliese 163! This brings the number of known, potentially habitable planets to 6.
A technique that allows radio astronomers to combine observations made simultaneously by multiple arrays has yet to detect any signs of extraterrestrial broadcast signals, Australian researchers have confirmed.
The astronomers from that European Space Observatory have helped reveal that rocky planets not much bigger than Earth are very common in the habitable zone around faint red stars.
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.
A team of scientists at Germany’s Max-Planck Institute for Astronomy has discovered a potentially habitable planet about 3.6 times as massive of Earth orbiting the star HD 85512, roughly 36.23 light years away.
