Suspected Alien Life on the planet Gliese 581d

There is a great mystery that has not been revealed until now. Is there another life beyond Earth? Moreover, the fact remains, our planet as insignificant dot ', compared to the contents of the universe.

That question inspired the scientists to find another life, and the search for Earth-like planets. One of which continue to be monitored are the planets in orbit that dwarf star, Gliese 581.

And, recent research shows planet Gliese 581d, a distance of 20 light-years from Earth is the first planet outside our solar system that could support life officially declared by scientists.

As loaded LiveScience, May 17, 2011, through the study of the latest atmospheric models, the astronomers found the planet is in the region 'habitable zone' has Earth-like conditions, including having the ocean and rainfall. This conclusion is consistent with some previous research models. Although not definitively find there is life up there.

Although the 'Earth-like' the scientists argue, if one day people can send a fleet expeditions, outer space explorers will find himself in an environment that is truly foreign, compared to Earth.

Red cloudy sky, not blue like the Earth. Also gravity is two-fold, to make weight anyone who stood on it to double. Not only that, the planet's atmosphere rich in carbon dioxide would not be easily inhaled by humans.

A new computer model that can simulate the Earth's climate has been shown outside of the previous assumptions are wrong and and confirm that Gliese 581d is the planet that could sustain life.

Scientists believe the findings could pave the way for the discovery of more potential life among the stars, including some strange and unexpected.

Dr Robin Wordsworth, a team member of the Institut Pierre Simon Laplace in Paris, said this finding is very encouraging. "Gliese system is very encouraging for us, because it is relatively close to Earth," he said.

"So with the future generation telescopes, we will be able to search for life on Gliese 581d directly."

Actually not only the planet Gliese 581d is targeted to scientists. There is also Planet Gliese 581g or known by the name 'World Zarmina'.

Not only an astonishing resemblance to Earth. But the scientists also found him mysterious signal emitted from the planet. Is Dr Ragbir Bhathal, scientists from the University of Western Sydney which saw a strange signal that in December 2008 - long before it was announced that there is a planet inhabited by creatures that can live in the orbit of dwarf star, Gliese 581.
