The 158-inch Mayall Telescope at the Kitt Peak Observatory isn't the largest telescope; it wasn't even the largest when it was built. (The 200-inch Hale Telescope at Mount Palomar is older.) It is used primarily for observations in the infrared spectrum.
She made contributions to astronomy, philosophy, & mathematics.
Thomas Harriot used the telescope for astronomical observations, specifically to study the Moon. He made detailed maps of the Moon's surface, documenting its craters and mountains. Harriot's observations were significant contributions to the field of astronomy during his time.
Newton invented the reflector telescope in the 1680's.
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.
Galileo Galilei was the first astronomer to make extensive use of the telescope for astronomy. He made several important discoveries, such as the moons of Jupiter and the phases of Venus, using his telescope in the early 17th century.
Geography, astronomy, navigation, oceanography and ordnance.
Galileo Galilei was an Italian physicist, mathematician and engineer, who contributed largely to the scientific revolution. He invented a pendulum clock, which was inspired by a swinging chandelier in the Cathedral of Pisa.
Galileo Galilei proved that objects in the solar system orbit around the sun, not the earth. He found this out by observing variations in venus's phases that could not be explained if all objects orbited the earth
Galileo Galilei used a telescope to make detailed observations of the stars and planets. He is most well known for suggesting that the Earth revolves around the Sun, and not the other way around.
Galileo Galilei studied physics, mathematics, astronomy, and philosophy. He made significant contributions to the development of modern science, including improvements to the telescope and observations of the heavens that supported the heliocentric model of the solar system.
Never, Dutchman Hans Lippershey did. Galileo improved it to make it magnify 30 times instead of just 3.
Galileo's most famous invention was the telescope, which he used to make groundbreaking observations in astronomy. He made important discoveries about the moon, Jupiter's moons, and the phases of Venus thanks to his telescope.
