Galileo Galilei ? the "father of modern astronomy"
Galileo Galilei (1564 ? 1642) was Galilao as he made ??improvements on the telescope, which was invented by Hans Lippershey "father of modern observational astronomy.". He used the telescope observations of sunspots, lunar mountains and valleys, the four largest moons of Jupiter and the phases of Venus to make.
He has also to a method for determining longitude at sea worked, with the positions of the satellites of Jupiter. In 1609, Galileo had built a telescope20-times magnification, with which he discovered mountains and craters on the moon. He saw that the Milky Way was made of stars. Later, he did what was 30-fold magnification.
Today astronomers have telescopes that are much bigger than anything used by Galileo. The $ 120 million Large Binocular Telescope (LBT) is sitting at 10,400 feet on Mount Graham in Arizona. Its components are manufactured in various countries around the world including USA, Italy and Germany. It was setCommissioning in October 2005. This telescope combines light from two mirrors to simulate a single telescope with a mirror. When it was put into operation, the astronomers used the LBT with a single primary mirror. That same year, the second mirror was put into operation.
Galileo, the "father of modern observational astronomy," do not have the equipment or the modern technology of today LBT, but the way for modern astronomy. There are many telescopesare similar to Galileo used. Many of them are small enough to be used in a backyard observatory.
