What year did Galileo invent the telescope?

Answer 1

Galileo (1564-1642) is often credited with the invention of the telescope, when in fact he only improved upon it.

The earliest telescopes were built in 1608 by three separate Dutch spectacle makers: Hans Lippershey (who patented one), Zacharias Janssen, and Jacob Metius. The following year, 1609, Galileo heard of the use of lenses in this manner, and built telescopes of his own, which quickly brought him great prestige in Venice. In 1610 his telescopes allowed him to observe the known planets and discover the first moons around Jupiter.

Answer 2

Galileo Galilei did not invent the telescope. He built his own in 1609 after learning of the invention, which was made in 1608.
He didn't. He heard of it in Summer 1609 when the news of the invention reached Italy.

The type of telescope used by Galileo has a convex object lens at the top end and a concave eyepiece lens. It is a type used in small Opera glasses now but is not used for astronomy after it was discovered that a convex eyepiece performed better by giving a wider field od view.
