Planetary System Gliese 581
2014-07-04 06:31:29

redOrbit Staff & Wire Reports - Your Universe Online 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. Officially, lead author Paul Robertson of Penn State’s Center for Exoplanets and Habitable Worlds and his colleagues write that the existence of Gliese 581g is...

Habitable Zone Larger Than Believed

[ Watch the Video: Life In The Habitable Zone ] Lee Rannals for redOrbit.com - Your Universe Online 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. University of Aberdeen scientists say that earth-sized planets are able to support life at least ten times farther away from stars than previously thought. This idea challenges the traditional 'habitable zone' theory...

More Than 1,000 Exoplanets Have Been Discovered Since 1992

Lee Rannals for redOrbit.com - Your Universe Online 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. Exoplanets, or alien planets, are those planets that exist outside of our Solar System. So far, scientists have discovered...

Three Habitable Super-Earths Discovered In Multi-Planetary Star System
2013-06-25 10:50:04

WATCH VIDEOS: [Gliese 667C Planetary Orbits] | [Animation of Gliese 667C System] Lee Rannals for redOrbit.com – Your Universe Online Astronomers have discovered a record-breaking planetary system with at least six planets orbiting its host star. New observations of Gliese 667C show for the first time that three of these six new planet candidates are super-Earths. In order for a planet to qualify as a super-Earth, it must exist within the "habitable zone," which is the zone around...

Exoplanet Found Within Gliese 163 Habitable Zone
2012-09-05 13:54:45

Michael Harper for redOrbit.com — Your Universe Online Good news! The ESO´s HARPS telescope (or High Accuracy Radial Velocity Planet Searcher) 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, most of which have been discovered in the past year. This rocky planet, called Gliese 163c, is considered a superterran, or super-Earth, and is a considerable 50 light years away from...

Focused Alien Hunt Coming Up Empty Thus Far

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. In a study posted online May 29 and scheduled for publication in the Astronomical Journal, experts at the Curtin University International Centre for Radio Astronomy Research used very long baseline interferometry (VLBI) to examine Gliese 581, a star which is orbited by planets...

Earth-Like Planets Very Common In Red Dwarf Systems
2012-03-28 10:44:51

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. A team of astronomers estimates there are tens of billions of these rocky planets in the Milky Way galaxy alone, and about one hundred in the Sun's neighborhood. The team used observations with the HARPS spectrograph on the telescope at ESO's La Silla Observatory in Chile. They had been searching for...

Super-Earth Transfer Of Life Unlikely
2012-03-22 04:04:10

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. "One of the big scientific questions is how did life get started and how did it spread through the universe," said Jay Melosh, distinguished professor of earth and atmospheric sciences. "That question used to be limited to just the Earth, but we now know in our solar system there is a lot of...

  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 (one light year is equivalent to roughly 5.9 trillion miles). Dan Vergano of USA Today reports that the discovery, led by the institute´s Lisa Kaltenegger, adds to the 572 planets orbiting nearby stars listed by the Extrasolar Planets Catalogue. Astronomers around...

Scientists said on Monday that a rocky planet outside our solar system is the first to meet key requirements for sustaining life. Modeling of planet Gliese 581d shows that it has the potential to be warm and wet enough to nurture Earth-like life. The planet orbits on the outer fringes of the star's "Goldilocks zone," where it is not so hot that water boils away, nor so cold that water is perpetually frozen.  "With a dense carbon dioxide atmosphere -- a likely scenario on such a large...
