Amino acid that is the basis of life on earth has been detected in the nebula of nine such as "hand Nebula cat" to a distance of about 5500 light years from Earth, compelling evidence to reinforce the theory that made the universe, National Astronomical Observatory of Japan the 23rd, teams such as announced.
There is a type called "type left" and "right type" form that do not overlap even like the amino acids, most of the amino acids that make up life on Earth type called "left type". Where in the infrared telescope installed in South Africa, was observed and hand Nebula cat, Tamura Tokyo University and his colleagues, have detected a special light called forward to draw a spiral with "circularly polarized light". When illuminated by the light, the molecules such as amino acids, that has the property of biased toward one "left die" and "right die."
If amino acids were made on earth, the "right type", "left type" is it could have been about the same amount, but you do not go to the left type reality that majority. For this reason, flying to earth ancient amino acid produced in the universe by irradiation with circularly polarized light of "left type" is attached to the meteorite, there is a theory and became the origin of life. I guess in the universe is based on the life also.
地球上の生命の元となるアミノ酸は宇宙で作られたという説を補強する有力な証拠を、地球から約5500光年離れた「猫の手星雲」など九つの星雲で検出したと、国立天文台などのチームが23日、発表した。
アミノ酸には形がそっくりでも重ならない「左型」「右型」と呼ばれるタイプがあるが、地球上の生命を構成するアミノ酸の大半は「左型」と呼ばれるタイプ。田村・東大教授らは、南アフリカに設置された赤外線望遠鏡で、猫の手星雲などを観測したところ、らせんを描いて進む「円偏光」と呼ばれる特殊な光を検出した。この光に照らされると、アミノ酸などの分子は、「左型」「右型」の一方に偏る性質があるという。
地球上でアミノ酸が作られたとすれば、「右型」と「左型」がほぼ同量できたはずだが、左型が大半という現実に合わない。このため、円偏光の照射により宇宙で生じた「左型」のアミノ酸が隕石に付着し太古の地球に飛来、生命の起源となったとの説がある。やはり生命の元は宇宙にあるんでしょうね。
