Habitable Zone Larger Than Believed
2014-01-08 14:32:50

[ 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
2013-10-25 14:17:10

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
2012-06-04 03:15:31

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...

Reports Confirm Existence Of Habitable Exo-Planet
2012-04-28 03:28:20

After re-evaluating information collected back in February, scientists reportedly confirmed on Friday that they had indeed discovered a planet outside of our solar system that is capable of supporting life. The planet, which was been dubbed Gliese 667Cc, orbits around a red dwarf star located 22 light years away from Earth, according to published reports from the Telegraph. Scientists told the newspaper that Gliese 667Cc lies in what they refer to as the "habitable zone," which means that...

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...

Astronomers Spot Fourth Potential Habitable Planet
2012-02-03 09:41:48

An international team of astronomers have discovered a potentially habitable planet 22 light years away orbiting a nearby star, reports The Telegraph. Scientists, led by Carnegie´s Guillem Anglada-Escudé and Paul Butler, discovered the triple star system with a planet orbiting one of the stars, clearly within the habitable zone, where its neither too hot nor too cold, making it suitable for liquid water to be present on the surface. The host star has a different makeup...

Image 1 - HARPS Finds Fifty New Exoplanets
2011-09-12 12:45:58

  Richest haul of planets so far includes 16 new super-Earths [ View Video ] Astronomers using ESO´s world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star. By studying the properties of all the HARPS planets found so far, the team has found that about 40% of stars similar to the Sun have at least one planet lighter than Saturn. The...

Libra (the scales) Constellation -- Libra (the scales) is a constellation of the zodiac. It is a fairly inconspicuous constellation and has no star of first magnitude, lying between Virgo to the west and Scorpius to the east. As the names of the brighter stars testify, it was at one point part of Scorpius' claws. Notable features The brightest stars in Libra form a rectangle: -- α Librae, Zubenelgenubi ("southern claw"), a visual binary; -- β Librae, Zubeneschamali...
