Scientists observations by radio telescopes to the young "quadruplets" stars, which contains four different gases and condensed into a block structure. White part of the filamentary gas clouds, dust blue part of the structure, the position of the red dot is a protostar evolution has entered the stage of celestial bodies, other newborn stars in black marker. Scientists have found that multiple births at the strange stars after "embryo" are very excited that the system could provide more clues to uncover the evolution of multiple star systems, which is the evolution of our solar system has quite different. In contrast, our sun seems to be a lonely star.
Most of the star system within the Milky Way stars are multi-structure, such as three or four star stellar systems, the solar system is only the sun a star, which makes solar system get a little strange. More interestingly, though the solar system is a single star system, but it has more planets, other stellar systems which do not have, which imply that the solar system has evolved innate potential for life? This is one of the aims of scientists looking for more star systems to try to reverse the solar system's uniqueness. The study results were published in "Nature" magazine, author Harvard? Smithsonian Center for Astrophysics (CFA) Professor Alyssa Goodman.
According to Professor Alyssa Goodman describes: the newly discovered quadruplets star about 825 light-years from us, with respect to the extrasolar planets discovered in recent years, the more than 800 light-years is a relatively long distance. Prior to this, scientists have discovered a molecular cloud protostar many more star systems in the direction of the constellation Perseus, the observations also hinted to have multiple "brothers and sisters" star systems in the Milky Way is universal. For multiple births systems, scientists doubt that how they are formed? Whether from the same stellar "nursery"? Whether they are from the same molecular cloud? Scientists are currently theoretical model to verify the conjecture.
The researchers believe that based on the density of these gases is estimated that the size of the original star system will be even greater, at least for the current two to three times, after which they are formed by the gravitational collapse of a newborn star, so we may be formed in three new stars embryonic detect traces of nuclear fusion. According to the latest observations from the four stars are at least 10,000 astronomical units, equivalent to the position of the boundary of the solar system's Oort cloud, the future of this "stellar womb" how evolution still needs further observation.
