Good News! Well, not for us but maybe for our next generations. 2012 is near and some of us think that Earth will end. Most of us assume that our Earth is unique and we wont die. But wait, think again. There are planet like Earth everywhere. We are so tiny like ants in this universe that we can't see the outer world. Finding this new planet 'Zarmina' with water and life proves that there are aliens out there. No matter what happens in 2012 or not, something will happen definitely in the future. What will happen? Well, we will meet aliens and we will be going on a vacation to their planet. Don't believe me? Watch the video and you will know the new planet.
Astronomers have announced they have discovered an earth like planet that could support the crucial conditions needed for life to exist. The new planet sits directly in the middle of what is referred to as the habitable or Goldilocks zone (Gliese 581 g), unlike any of the nearly 500 other planets astronomers have found outside Earth's solar system. It also is in Earth's galactic neighbourhood, suggesting that plenty of Earth-like planets circle other stars. Astronomers say the planet is neither too far from its star, not too close and could contain liquid water.
Butler says astronomers have identified about 400 planets in the past 15 years. He explains he and fellow planet hunters observed the faint red dwarf star Gliese 581 using one of the world's biggest telescopes at the W.M. Keck Observatory in Hawaii. Since they started observing this star 11 years ago, they have identified six planets that orbit around Gliese 581. But only planet G is the right distance from its star, in that so-called "Goldilocks zone." "The truly exciting thing about this discovery is that the star is so nearby, and we found it relatively quickly in the scheme of things," says Butler. "So this suggests that potentially habitable planets are very, very common." "So nearby" is a relative phrase. This new planet is about 193 trillion kilometers away. And "potentially habitable" means the planet could potentially sustain life, but not necessarily life as we know it.
This newly discovered planet has a mass about three-to-four times that of Earth. And it is locked into position with its star, so one side is always in dark and one side always in light. And, as far as orbits go, Gliese 581G's 37-day orbit around its star is far shorter than the 365 days it takes our planet to orbit the Sun. "When you listen to that you think, 'Wow! That must be way too close to the star for there to be life because that is a short orbit. So this is shorter than the orbit of Mercury around our own Sun. It must be terribly hot.' Actually, that is not the case," says Doug Hudgins of NASA's exoplanet exploration program. He says Gliese 581 is a red dwarf star that is much cooler than our Sun and emits far less radiation.
