Galileo was an italian astronomer who developed the telescope as well as found four major satellites of jupiter.

@Kam: your definition of discovery is similar to innovation. Discovery is the finding of an existing entity which until then was never known.

What is "heliocentric theory"?

Galileo discovered his own telescope which helped in the discovery and observation of lunar mountains and valleys, sunspots, phases of venus and four largest satellites of jupiter.

Copernicus is first said person that the earth revolves around the sun not the sun to earth. This statement is totally wrong according to Kristen fellows and for that Copernicus lost his life.

Discovery - The process of finding information, a place or an object, especially for the first time, or the thing which is found the discovery of electricity.

Leonardo made many scientific discoveries. A journey/voyage of discovery.

The discovery of a body in the undergrowth started a murder enquiry.

Inventions - Something which has never been made before, or the process of creating something which has never been made before.

The world changed rapidly after the invention of the telephone. A most amazing invention.

Is he discovered telescope, four satellite and also pendulum?

Who discovered the telescope finally Galileo or Lippershey? And what is Copernicanism or Copernican principle?

It is quite a common belief that Italian astronomer Galileo Galilei invented the telescope but this is not strictly true. The earliest workings towards the design of the refracting telescope were made by German-Dutch lensmaker Hans Lippershey (above) in 1608. During Lippershey's time, the name 'telescope' was not used until three years later and he referred to his design as a 'Dutch perspective glass', which he used for 'seeing things far away as if they were nearby. '.

Galileo, though, was the first person to use a telescope for astronomical purposes after hearing about Lippershey's work in 1609. He improved on Lippershey's design and using his new telescope in 1610, he discovered the four largest moons of Jupiter (Io, Ganymede, Callisto and Europa) and physical features on the Moon.

The first person to apply for a patent for a telescope was a Dutch eyeglass maker named Hans Lippershey (or Lipperhey). In 1608, His telescope had a concave eyepiece aligned with a convex objective lens. Copernican principle, named after Nicolaus Copernicus, is a working assumption that arises from a modified cosmological extension of Copernicus' Sun centered Heliocentric Universe.

The Copernican principle assumes that neither the Sun nor the Earth are in a central, specially favored position in the universe. More recently, the principle has been generalized to the relativistic concept that humans are not privileged observers of the Universe. In this sense, it is equivalent to the mediocrity principle, with important implications for the philosophy of science.

Galileo lived in renaissance period.
