Seed of Life from Comets
FOR the first time have identified one of the most fundamental chemical blocks of life inside a comet. The results of this study was issued by the U.S. space agency (NASA).
Glycine is a kind of amino acids found in proteins, the complex molecules that are used by organisms to build and maintain their systems.
These elements detected from the comet Wild-2 in 2004 and captured by the Stardust spacecraft NASA. Thoughts about life from the seed of the 'scattered' by the comet in the early formation of the earth today was the talk everywhere.
Some scientists use this theory for millions of years ago. Attack balls of ice and rock that brought barrage of chemicals is important as a sign of life on our planet. "The research will be of glycine in comets supports thinking about the most basic chemical blocks for life are common in space, and strengthen the argument that states the existence of life in this universe," said Dr. Carl Plicher, director of NASA's Astrobiology Institute.
Glycine was found earlier in the meteor. Besides the existing studies of the interstellar gas clouds, but found the Stardust became the first image that comes from the comet.
NASA spacecraft crossed the comet 81p / Wild-2 as wide as 5 km in January 2004. Investigators that the plane sweep the particles on the surface of the object along the 240 km (149 miles) from the axis of the comet, or nucleus. Very small particles, their size or one thousandth of a millimeter, which is then brought to earth in 2006.
