Galileo di Vincenzo Bonaiuti de' Galilei (15 February &#;– 8 January ), commonly referred to as Galileo Galilei (, ; Italian:[ɡaliˈlɛːoɡaliˈlɛːi]) or mononymously as Galileo, was an Italian[a]astronomer, physicist and engineer, sometimes described as a polymath. He was born in the city of Pisa, then part of the Duchy of Florence.[8] Galileo has been called the father of observational astronomy,[9] modern-era classical physics,[10] the scientific method,[11] and modern science.[12]
Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of the pendulum and "hydrostatic balances". He was one of the earliest Ren

Galileo&#;s Observations of the Moon, Jupiter, Venus and the Sun
Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy.
Born in , Italian astronomer Galileo Galilei's observations of our solar system and the Milky Way have revolutionized our understanding of our place in the Universe.

If Galileo were around today, he would surely be amazed at NASA's exploration of our solar system and beyond.
After learning of the newly invented "spyglass," a device that made far objects appear closer, Galileo soon figured out how it worked and built his own, improved version. In , using this early version of the telescope, G

Galileo and the Telescope
‘Now it is our advantage, that by the help of Galileus’ glass, we are advanced nearer unto them, and the heavens are made more present to us than they were before’.

as the International Year of Astronomy marks the kvartet hundredth anniversary of Galileo’s use of the telescope. That he himself did not create it he makes klar in his Siderius nuncius (Venice, ):
‘A few days later the report [that a certain Fleming had constructed a spyglass] was confirmed to me in a letter from a noble Frenchman at Paris, Jacques Badovere, which caused me to apply myself wholeheartedly to inquire into the means by which I might arrive at the invention of a similar instrument. This inom did shortly afterwards, my basis being the theory of refraction.’ *
In fact the telescope originated in in the Netherlands and there was some competition over
