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 them. Their names are: Io, Callista, Europa and Ganymede. He discovered them in January 1610. == ==Galileo Galilei in 1610.
Galileo di Vincenzo Bonaiuti d'e Galilei. He found them with his refracting telescope in the year 1600's
He Discovered The Jovian Planets ,i.e., jupiter, saturn, neptune and uranus
Galileo Galilei was the person credited with discovering the four largest moons of Jupiter, including the one we now call Ganymede.
The four largest moons - were named as a group after Galileo because of him being the first person to obseve them through his own invention - the telescope.
That was Galileo.
Galileo's greatest discovery was the discovery of jupiter's moons and rings.
Yes. That is why they are called the Galilean Moons
Galileo Galilei
Galileo did NOT discover Jupiter; just Jupiter's 4 largest moons.
Yes he did! Galileo was the first one to discover Jupiter's 4 moons.
My answer is four moons that Galileo found on or near Jupiter.
Uranus was not discovered by Galileo Galilei. Some of the things that Galileo did discover was that there were four moons around Jupiter and that everything falls at the same speed.
Galileo discovered sunspots in 1612. He also discovered the phases of Venus and four of Jupiter's moons during his lifetime.
Aristotle did not discover the moons of Jupiter or mountains on the moon. The discovery of Jupiter's moons was made by Galileo Galilei in 1610. Mountains on the moon were observed by Galileo as well, using his telescope in the early 17th century. Aristotle lived in ancient Greece in the 4th century BC and did not have access to the technology needed for these astronomical observations.
Galileo did not discover Saturn. It was know of by the ancients. It can be seen at certain time without the aid of instruments.
Galileo Galilei did not discover any moons orbiting Saturn; his observations were primarily focused on Jupiter. He is credited with discovering four large moons of Jupiter, known as the Galilean moons, in 1610. Saturn's moons were discovered later, with the first being Titan, which was observed by Christiaan Huygens in 1655.
