galileo used glass with a layer of plastic.
about 400 years ago galileo made his own telescope by putting tow lenses together in a wooden tube
Galileo turned a refracting telescope, which uses lenses to gather and focus light, skyward in 1610. This allowed him to make groundbreaking astronomical observations such as the moons of Jupiter and the phases of Venus.
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)
Galileo wasn't the first to make a telescope but he discovered the telescope at the age of 46.
Galileo Galilei did not invent the first telescope; it was invented by Dutch eyeglass maker Hans Lippershey in 1608. Galileo, however, heard about this invention and created his own improved version in 1609, which he used to make groundbreaking astronomical observations.
Galileo Galilei first used the "new" telescope in 1609
Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person to use a telescope. That person would be Hans Lippershey. Hans Lippershey was born 1570 in Germany, but was raised in Holland. He invented the first refracting telescope in 1608. A lens maker, he designed this telescope from two lenses and applied for a patent, intending that it would be important for the military. He successfully demonstrated the usefulness of his refracting telescope to the military.
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.
