The origin of the life?

Tweet

t was the 18 January of 2000 when a ball of fire appeared in the sky of Canada, accompanied by strong detonations. The sun was darkened when the sphere penetrated in the terrestrial atmosphere, going then to break on the frozen surface of the Tagish Lake, in the Yukon, to north of British Colombia. Its fall was also noticed by the satellites in geostationary orbit around the Earth. To he/she dictates some experts it had to be a great deal a fragile meteorite, since you/he/she was reduced in dust, breaking himself/herself/itself and scattering later his fragments on a vast superficie.Nove days, Jim Brook, a resident astrofilo in the proximities, was on the frozen surface of the lake to look for fragments of the meteorite and when he/she saw them it picked up until of it it was able putting them in a plastic pouch not to contaminate them. The following day, a sharp pain snowfall made difficult further recoveries. To find of of it new you are had to attend the spring. Briskly working against the time and the ice that it was quickly loosened (heated by the solar light, the dark stones had begun to sink in the ice), in spring the Canadian scientists succeeded in recovering around 500 fragments of the rare recovered material meteorite.Il you/he/she was quickly frozen so that to avoid terrestrial contamination. "It smells of sulphur because it is the only one to preserve the cocktail of molecules from which it had origin the Solar System and perhaps the same life", they were the words of someone that you/he/she had participated in the search. In fact, the meteorite of the Tagish Lake, shares the origins with our Sun. Both have origin from the primordial nebula, to the dawn of the solar system. The scientists think that the meteorite is the most ancient body celestial joint on the Earth, and that this recovery can revolutionize their knowledges on the origin of the Solar System and also on the life of our planet. To seven year-old distance from the recovery, the researchers of the NASA of the Johnson Space Center, using himself/herself/itself of 2 powerful persons and sophisticated jewels of the nanotecnologia (JEOL transmission electron microscope) installed in the laboratories of the Center of Houston, you/they have found material organic preserved in an only fragment of condrite carbonacea, a rare type of meteorite rich in organic residues. Very unusual isotopic compositions have been noticed in the nitrogen and in the hydrogen, molecules organic strangers that go up again ago very probably to 5 billion years of years. He/she is thought, in fact, that the organic globules very probably originate from the cold molecular cloud that has given the light to our solar system. The organic subject of the meteorite is subject to an intense interest from the scientists. Since it is a material formed him to the dawn of the solar system, it is supposed could have entertained forms of life very in advance. In fact, from the analyses effected on the micro fragments it is hypothesized that the Earth can have been sowed by the life organic present in these globules in the same period in which the Life has appeared on our planet. The origin of the life stays, still, a problem irrisolto in the natural sciences."
