To find life outside our solar system, more and Me and the.

<P> An international research team recently in the UK "Nature" magazine published an article that they use "gravitational microlensing" technology, to detect an Earth-like planets, it may be the smallest ever found outside our solar system and the farthest from Earth .terrestrial planets. .Scientists involved in the study, said the results found an increase in the hope of life outside our solar system. .</ P> <P> still much larger than the Earth </ P> <P> "Nature" magazine published a research report that the planet is named OGLE-2005-BLG-390Lb, is located in the southern hemisphere constellation Sagittarius over the area, close to the .galactic center, more than 20,000 light years from Earth. .1 light for the light transmission distance in a year, equivalent to 10 trillion kilometers. .</ P> <P> participated in the study of the U.S. Lawrence Livermore National Laboratory said that the planet is so far outside the solar system found in humans in the most asteroids, the Earth's 5.5 times the volume than the previously discovered 160 .Terrestrial planets are small. .Scientists had found the most Earth 7 times the volume of the asteroid. .</ P> <P> from France, Poland, Denmark, Germany, Austria, Chile, Australia, New Zealand, the United States, South Africa, Japan and the United Kingdom's 32 institutions participated in the study. .</ P> <P> technology helps a lot </ P> <P> that benefit from a planet called "gravitational microlensing," the new technology. .</ P> <P> the famous 20th century scientist Albert Einstein first proposed 30 years, moving to another planet or star in front of distant stars, the front of the object is sometimes like a "lens" as objects to the rear enlarge .It seems to be more bright and the observer, the so-called "gravitational lensing" effect. .</ P> <P> advantage of this phenomenon in recent years, scientists have developed a new detection technology known planets - gravitational microlensing technique. .Last July, scientists in Chile, Australia and South Africa telescope to infer the existence of the planet. .</ P> <P> astronomer Kem Cook participated in the study, said: "micro-lens (technology) tells us that far from the ordinary solar system planets to (run), and other technology can not detect the planetary data." < ./ P> <P> newly discovered planet around a brown dwarf is running, both distance is about 2.6 times the Sun-Earth distance, or 2.6 astronomical units. .Smaller dwarf star is a quality, volume and brightness equal to or less than the average star. .</ P> <P> help search for extraterrestrial life </ P> <P> brown dwarfs as low energy radiation, this new found planet's surface temperature is about minus 220 degrees Celsius, not suitable for human habitation. .However, New Zealand scientists involved in the study thought that the discovery order was to find habitable extrasolar planets want to increase. .</ P> <P> Christchurch, New Zealand astronomer Karen Pollard, said: "We find that Earth-like planets the size and suggested that there may be a considerable number of these objects. They are just really .difficult to find. "</ P> <P> 菲利普约克 Associate Professor, University of Auckland New Zealand said the previous use of micro-lens technology found in the majority of bulky planets, gaseous, surface temperature is very high. .The newly discovered planet Fengyun Neptune and Uranus with a similar size, and that the two planets composed of rock and ice cores, the outer layer is mainly hydrogen and helium and other substances. ."Using gravitational microlensing technique can find planets as small as Earth, find such a planet is only a matter of time." </ P> <P> under a more exciting: the spring empire - a sequel to Murder Caused bread (Hugo .new work) </ P> <P> most mysterious of the strangest, most incredible of all in science and technology magazine </ P> <P> </ P> </ p>.
