Galileo Galilei is credited with being the first to use a telescope to study the heavens systematically in the early 17th century. His observations of celestial bodies through the telescope led to significant discoveries in astronomy.
He invented the reflecting telescope. Galileo was the first to use the telescope for studies of the heavens.
Galileo didnt invent the telescope. He improved on the idea of a telescope. The first telescope was made by a Dutch lensmaker named Hans Lippershey, and the chineese used crystal ball lenses to see far distances back in the 400B.C.s. However, Galileo did improve on the telescope in 1611, but only enough to see into the heavens (as the original telescope was alot more of a powerful spyglass)
Note that Galileo did not invent the telescope. He was, however, the first person to use a telescope to examine the heavens. Previously, telescopes had only been used to look at distant locations here on Earth.
Galileo wasn't the first to make a telescope but he discovered the telescope at the age of 46.
Galileo Galilei first used the "new" telescope in 1609
Galileo perfected the telescope.
Galileo used and made the first telescope.
people think Galileo made telescope because he was the first one made up telescope
Galileo created his first telescope in around two months in 1609. It was a refracting telescope with a convex objective lens and a concave eyepiece. This instrument revolutionized astronomy and allowed Galileo to make groundbreaking astronomical observations.
