French astrophysics established that a source practically all water in a stratosphere of Jupiter is the comet Shoemaker – Levy 9, fallen to a planet in 1994. Conclusions of researchers are based on supervision over a stratosphere of the gas giant, carried out by means of a space telescope Herschel. Data were obtained in the infrared range, with lengths of waves of 66.4 and 179.5 micrometers, where water has characteristic peaks of radiation. In work were used the spectrometers of PACS and HIFI established on a telescope. Made on the basis of data Herschel the card of distribution of water in a stratosphere of Jupiter was not uniform: in the southern hemisphere its concentration was much higher, than in the northern. According to astrophysicists, such heterogeneity unambiguously says, that its source is the comet Shoemaker- Levy 9, which in 1994 entered just into the southern hemisphere. Scientists specify that the water rising within of a planet would be distributed evenly. To other, more uniform distribution lead also other alternative scenarios, for example, water drift from the outside together with a space dust. The comet Shoemaker-Levy 9 was open on March 24, 1993. In 1994 its fragments, which have been broken off earlier by gravitation of a planet, entered into the atmosphere of Jupiter at a speed of 64 kilometers per second. The falling, which has caused well distinguishable indignations in the atmosphere of the gas giant, the first directly observable collisions of heavenly bodies in Solar system.
