The Universe Is There Another Solar System?
Anyone ever imagined, that in addition to our solar system, solar system may still have the 2nd or 3rd in the universe. however, the concrete in another solar system where it is? During this time, the issue being debated endlessly, where along with the discovery of planetary systems around Lira (in the constellation Vega), there are thought to have discovered “solar system” to-2 in the universe, and has provided illustrations in finding a large number of “Solar System” in the universe.
How the discovery of “solar system” to-2 in the universe?
At last in January 1983, the United States, the Netherlands and the UK successfully launched infrared astronomical satellite. Later, using the satellite is also unexpected astronomers found the main star of a binary star in the constellation ¾ Lira Vega is a circle of similar solid planet.
Material around the constellation Vega Vega absorb heat radiation, and emit infrared. Infrared astronomy satellite would have received it emits infrared. Compared with the intensity of the four areas that are not receiving the same wave, can calculate the temperature of the object is 90K (-180 ° C ±). Generally, the lower limit temperature of the fixed stars of approximately 500K. Temperature is 90K, this means that the object is a planet. Moreover, if the constellation Vega actually have planetary systems, then it would be equivalent to the outer planets. Objects with temperature thus can only be captured with an infrared telescope with a wavelength of tens of microns.
The satellite, launched in cooperation the U.S., the Netherlands and the UK is an infrared astronomical satellite a world first, which is used primarily to detect the source of infrared all-weather, or in other words, keep records and books on the list of infrared sources. Infrared astronomical telescope can not be used to investigate low-temperature objects in the universe. Because water and carbon dioxide in the atmosphere has absorbed large amounts of infrared heat from the earth and the universe, then will issue a mutually interfere with infrared. Infrared astronomy satellite will perform cooling with liquid helium extra low temperature, because it’s new presence on these findings.
Distance to the earth constellation Vega is 26 light years, with a diameter 2.5 times higher than Jupiter, and the mass was about 3 times his Jupiter, the surface temperature of about 10000 ° C, higher than about 6000 ° C surface temperature of the sun. Vega constellation appears in 1 billion years ago, while the emergence of the sun is at 4.5 billion years ago, a comparison of the constellation Vega was much younger. And the earth came about simultaneously with the sun.
According to the general hypothesis of planet formation, the star when it appears, in a circle around it spread a cloud of gas molecules in a 100-fold scale of the solar system, and because of the interaction in the long run so that divided thousands of clumps of matter, which is hereinafter become planets.
Tokyo Observatory astronmi been announced, that they found a “baby planet system” in the constellation Orion nebula and other areas with radioteleskop.
Findings from the infrared astronomical satellite and astronomical observatory Tokyo, apparently can not be regarded as the same stage in the process of planet formation. By researching and analyzing in depth the second stage and more accurately depicts the constellation Vega planetary images, clearly this is an important topic among the astronomy facing the world today.
