Earth-like extrasolar planet discovered (Source: The Independent) A planet similar to Earth has been found orbiting a distant star by astronomers who believe they are getting closer to discovering an alien world inhabited by extraterrestrial life.
The new planet is five times the size of Earth but is itself unlikely to harbour life because it is probably covered in frozen oceans with average temperatures of around minus 220C.
However, the scientists behind the discovery believe the find marks a breakthrough in the search for relatively small, rocky planets such as Earth where temperatures are neither too hot nor too cold for life.The scientists said that the discovery showed it was technically possible to discover a planet in a temperate "habitable zone" around a far-away sun that would permit the existence of liquid water, which is believed to be necessary for life.The new planet, designated OGLE-2005-BLG-390Lb, is the smallest and the coldest planet yet discovered beyond the solar system. It orbits a star towards the centre of the Milky Way galaxy located 20,000 light years away in the constellation Sagittarius.
"This has huge implications for finding life," said Stephen Kane of the University of Florida, one of the 73 astronomers from the 32 institutions around the world involved in the study, published today in the journal Nature. "The good thing about this is it shows that planets this size might be quite common in habitable zones," Dr Kane said.More than 150 planets are known to exist outside our solar system but the vast majority are large, gaseous planets, like Jupiter. The latest planet has an orbit three times the distance between the Earth and the Sun, meaning its temperatures are similar to those of permanently-frozen Pluto.
Maybe a little lol but of course I always got two bread loafs floating in opposite directions to laugh at😉Or are you lying about being from this planet?
