where are jet streams located in the atmosphere On earth, near the altitude of the tropopause what are they? Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets. what are the applications of these fast flowing air currents? On Earth, the northern polar jet stream is the most important one for aviation and weather forecasting. these air currents form in any other planets? Yes, on Jupiter for instance how they are formed there? On Jupiter, they are caused by the convection cells that form the familiar banded colour structure and are driven by internal heating. what is the above mentioned planet composed of? Primarily composed of hydrogen with a quarter of its mass being helium. It may also have a rocky core of heavier elements. how is the atmosphere there? It has the largest planetary atmosphere in the Solar System. what time it takes to complete one revolution around the sun? 11.86 years what is flyby mission? Operations where spacecrafts are brought within observation range to closely monitor and study astronomical objects. has any flyby mission carried out for this planet? Yes, the Pioneer and Voyager missions to name two of them. when was the first one carried out? 1973 how many natural satellites does this planet have? 79 can you mention some of them? Io, Europa, Ganymede, and Callisto to name a few who discovered the first one? It was first observed by Galileo Galilei. who is the above mentioned person? He was an Italian astronomer, physicist and engineer, sometimes described as a polymath, from Pisa.

Galileo Galilei [SEP] Introduction
His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the observation of the four largest satellites of Jupiter, the observation of Saturn's rings, and the analysis of sunspots. Galileo's championing of heliocentrism and Copernicanism met with opposition from within the Catholic Church and from some astronomers. The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture".
