SOLAR SYSTEM

Detailed explanation-1: -In 1609, using this early version of the telescope, Galileo became the first person to record observations of the sky made with the help of a telescope. He soon made his first astronomical discovery.

Detailed explanation-2: -Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the “Danish perspective glass” in 1609, Galileo constructed his own telescope. He subsequently demonstrated the telescope in Venice.

Detailed explanation-3: -Galileo’s telescope Galileo was the first to point a telescope skyward. He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky-the Milky Way. He also discovered the rings of Saturn, sunspots and four of Jupiter’s moons.

Detailed explanation-4: -Galilean telescope, instrument for viewing distant objects, named after the great Italian scientist Galileo Galilei (1564–1642), who first constructed one in 1609. With it, he discovered Jupiter’s four largest satellites, spots on the Sun, phases of Venus, and hills and valleys on the Moon.

Detailed explanation-5: -On this day in 1609 Galileo Galilei demonstrated his first telescope to Venetian lawmakers, including Leonardo Donato, the Doge (ruler) of Venice. At the time, Galileo taught geometry, mechanics and astronomy at the University of Padua, which was part of the Venetian republic.

Detailed explanation-6: -Galileo was the first one who used the telescope for astronomy, making wonderful discoveries about our Moon, the moons of Jupiter, and other things. A photograph of one of Galileo’s telescopes is shown below. However, Galileo did not invent the telescope.
