• Heavenly Coup

    The planet Jupiter seems to the naked eye a point. And if you look through a telescope, you can see that in fact, Jupiter is a shiny ball. It turned out that not only the Earth has a satellite. Not far from Jupiter, Galileo noticed four more small light balls. These were the moons, or satellites, of Jupiter.

    Turning the tube to the Milky Way, Galileo clearly saw that it was a cluster of countless stars. Now it was no longer possible to say that the Milky Way is an accumulation of terrestrial fumes lit in the heavens. It was a whole revolution in the science of the universe.

     One hundred years before Galileo, Copernicus argued that the Earth and other planets revolve around the Sun. But then only a few were convinced by the arguments of Copernicus. Now it became clear that Copernicus was absolutely right. Two glasses inserted into the tube showed firsthand that the Earth is not at all the center of the universe. Thus, they undermined the foundation of the Christian faith.

    Galileo was captured by the Inquisition, they nearly burned him at the stake. He was saved only by the fact that he publicly renounced his "heresy"...

    After Galileo, they began to build telescopes with even larger lenses. However, here, as in a microscope, colored stripes strongly disturbed at first. Only after they learned how to cook optical glass, it became possible to build large telescopes.

    Telescopes, in their structure similar to the Galilean ones, that is, collecting light by a lens, are called refractors. The larger the refractor lens, the greater the magnification that the telescope gives. The largest lenses in modern refractors have a diameter of more than one meter.
