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...

Image 1 - HARPS Finds Fifty New Exoplanets

  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...

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...

Astronomers have discovered the second super-Earth exoplanet [1] for which they have determined the mass and radius, giving vital clues about its structure. It is also the first super-Earth where an atmosphere has been found. The exoplanet, orbiting a small star only 40 light-years away from us, opens up dramatic new perspectives in the quest for habitable worlds. The planet, GJ1214b, has a mass about six times that of Earth and its interior is likely to be mostly made of water ice. Its...

Recent discoveries by astronomers have brought the official number of planets outside of our solar system to over 400. The team that constructed the High Accuracy Radial Velocity Planet Searcher (HARPS) reported the discovery of 32 new planets outside our galaxy. HARPS is a spectrograph that is attached to the European Southern Observatory's telescope in La Silla, Chile. Using the spectrograph, scientists are not able to gather images of planets, but they are able to make observations based...

An Australian magazine is giving people a chance to send a message to far-distant planets, assuming anyone is out there to listen. The messages would be sent to Gliese 581d, a water-covered world eight times the size of Earth, COSMOS Magazine said. The planet, 20 light years from Earth, is the closest Earth-type planet discovered so far. It's like a 'message in a bottle' cast out into the stars, said Wilson da Silva, editor of COSMOS. What's interesting is not just whether there's anyone...

Astronomers claim to have discovered an exoplanet that is the most similar to Earth in terms of mass than any previously discovered. Found in the constellation Libra, the planet known as Gliese 581 represents about twice the mass of Earth. Astronomers have previously identified some 300 exoplanets, but most are much larger than Earth. "This is by far the smallest planet that's ever been detected," said Michael Mayor, from the Geneva Observatory, Switzerland. "This is just one more step in the...

An international team of scientists has found that giant exoplanets orbiting very close to their stars could lose a quarter of their mass during their lifetime.  The team found that planets that orbit closer than 2% of an Astronomical Unit (AU), the distance between the Earth and the Sun, may lose their atmospheres completely, leaving just their core.  The team, led by Dr Helmut Lammer of the Space Research Institute of the Austrian Academy of Sciences, believe that the recently...

MESSAGES to a planet which closely resembles Earth were yesterday beamed into space. Some 501 - from Sir Patrick Moore, McFly and TV nutritionist Gillian McKeith among others - will take more than 20 years to reach Gliese 581c. The planet, 120 trillion miles away and discovered last year, is the closest body to us which appears to be suitable for life. Pictures of personalities such as Hillary Clinton and Richard and Judy have also been transmitted. (c) 2008 Daily Mirror. Provided...

More than 500 images, text messages and drawings were transmitted to a planet 20 light years away from Earth on Thursday by a massive radar telescope in the Ukraine that normally tracks asteroids. The recipient planet, known as Gliese 581C, was selected because scientists believe it is capable of supporting life.  However, any reply to the messages would not return to Earth for 40 years.  The effort is part of a competition known as "A Message From Earth" that is being sponsored...
