The formation of the original molecule of life may come from stars.

<P> Galaxy a big, bright star of life on Earth has a large number of extremely important and complex molecules, the new findings show that the formation of the original molecule of life may come from stars. .</ P> <P> U.S. scientists recently said that a big galaxy, the brightest star of life on Earth has a large number of extremely important and complex molecules, the new findings show that the formation of the original molecule of life may come from stars. .University of Arizona research team used a radio telescope to red supergiant star VY Canis observe the outer layer of the gas found traces of a variety of complex molecules, including hydrogen cyanide, a silicon oxide, sodium chloride, sulfide and carbon .nitrogen and phosphorus. .One particular interest of phosphorus nitride, because the molecules in interstellar space rare, it is the basic building material of DNA and other essential components of life. .</ P> <P> VY Canis is an old star about 5,000 light years from Earth, the sun's mass is about 25 times to 50 times the brightness of the sun. .Stars in the aging process will emit a lot of gas. .Previously it was believed that these gas molecules will be the star in the intense ultraviolet radiation damage. .New observations show that this is not the case, the outer layer of VY Canis some dust particles in the gas clumps, like shield the molecules within the same protection from damage. .</ P> <P> VY Canis rich in oxygen, it is generally accepted that around in such stars, the excess oxygen atoms will take all the carbon atoms, carbon monoxide, should not have other types of carbon compounds such as hydrogen cyanide .acid and sulfide and carbon. .Observations point to overthrow the old, which means that the outer gas chemical composition of stars can be very complex, the birth of the universe, to prepare materials for the life of chemical reactions than people originally thought to be much more active. .</ P> </ p>.
