No, Venus was already known of in Galileo's time.
No. He discovered the phases of venus.
In the year 1610
Galileo discovered sunspots in 1612. He also discovered the phases of Venus and four of Jupiter's moons during his lifetime.
He did not discover the planet Jupiter. He only used his telescope to see its four largest moons. The planet is and always has been visible to the naked eye and was known to people since ancient times.
Well yes and no. The phases of the moon were understood well before Galileo --- however Galileo discovered the moons of Jupiter and no doubt their associated phases --- as well as the phases of Venus.
Galileo discovered, in his observations of the different phases of Venus, that Venus and the Earth were revolving around the Sun. This was contrary to the misconception at the time that everything revolved around the Earth.
Galileo discovered four of Jupiter's moons. He also discover that Saturn has rings. Also, he saw that Earth was not in the center of the solar system, and that Venus has a face like the moon.
Galileo Galilei first recorded phases in Venus in 1610, and published his findings in 1613.
Galileo discovered the moons of Jupiter and observed the phases of Venus, providing evidence to support the heliocentric model of the solar system. Herschel discovered the planet Uranus and infrared radiation, expanding our understanding of the universe.
No, it was Johannes Kepler who discovered that planets orbit the Sun in elliptical paths. Galileo's observations of the moons of Jupiter and phases of Venus supported the heliocentric model proposed by Copernicus.
In 1610, Galileo used the telescope to discover four moons revolving around Jupiter.The motion of these moons proved that not everything in the sky revolves around Earth.Galileo's observation of Venus also supported the heliocentric system. Galileo knew that Venus is always seen near the sun. He discovered that Venus goes through a series of phases similar to those of Earth's moon.
