Astronomers: There is a '100%' life on this planet!

If confirmed, the exoplanet, named Gliese 581g, would be the first Earth-like world found residing in a star's habitable zone, a region where a planet's temperature could sustain liquid water on its surface. The team that found the planet is hopeful that they'll uncover signs of life there as well. During yesterday's press event, UC Santa Cruz astronomy and astrophysics professor Steven Vogt said, "Personally, given the ubiquity and tendency of life to thrive everywhere it can, I would say, my own personal opinion is that the odds of life on this planet are 100 percent." The discovery of the planet will be reported in the Astrophysical Journal by Vogt, Butler, and their coworkers. The discovery of the planet will be reported in the Astrophysical Journal by Vogt, Butler, and their coworkers. With this discovery, the number of alien planets in our solar system has increased to over 400. Most of them are enormous gas giants, although a couple are just a few times Earth's mass. One of two new planets identified by the researchers, Gliese 581g brings the total number of planets in orbit around the neighbouring red dwarf star Gliese 581 to six. Researchers have determined that the newly discovered planet Gliese 581f falls outside the habitable zone. The star is found in Libra, 20 light-years from Earth. The average distance travelled by a light year is around 6 trillion miles (10 trillion km). Typically, red dwarf stars are 50 times less luminous than the Sun. Planets orbiting these stars may be considerably closer to them and yet be inside the habitable zone since they are much colder. Gliese 581g is estimated to be 0.15 astronomical units from its star, putting it within range for a 37-day orbit. The average distance between Earth and the sun is measured in astronomical units, with one unit equal to around 93 million miles (150 million km). With six planets around their star in roughly circular patterns, the Gliese 581 system now resembles our own in a hazy way.
