COMET WILD 2

One hundred years after Barnard’s comets photographs, the most detailed images of a comet are those taken by the NASA probe Stardust. Launched in 1999, this probe accomplished in 2004 an extraordinary series of shots, also tri-dimensional, of the comet Wild 2’ nucleus, and brought to the Earth dusts of its tail, in which were found traces of amine and large carbon chains, that are the outlines of the organic molecules at the basis of the life forming.



In the Nasa picture: orbits of the Earth, of the comet and of the probe Stardust.
