how much more immature can yall be ?!
seriously!! ppl look this stuff up to get help, immaturity is for facebook and high school
the heavenly bodies were composed of material substance just like Earth, not pure orbs of light.
Galieo discovered that the moon has mountains and that the Sun spins. He also discovered that Venus has phases like the Moon. One of Galileos most important discoveries was that Jupiter has four moons that orbit around it.
Galileo made important discoveries with the telescope. The moons of Jupiter could be seen orbiting round Jupiter, the first objects discovered that did not orbit round the Earth, as people believed then.
He also discovered the phases of Venus, and noticed a gibbous phase when Venus is far off and remote.
Both these major discoveries demonstrated faults with the accepted Ptolemaic theory. Galileo concluded that the other theory, the Copernican system with the Sun at the centre, must be right.
In the end Kepler's system was found to be correct. All it has in common with the Copernican system was the idea that the Sun in the centre, but other than that Kepler used an entirely new concept of elliptical orbits.
Galileo's observations seemed to indicate that the heavenly bodies were made from material substances similar to Earth. Before that, it was thought they were just orbs of light.
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.
He built his first telescope and started to make observations. He discovered the phases of Venus and sunspots. He built his first telescope in 1609. Galileo's taught mathematics and actually made a few discoveries in physics. When he heard about the inventor of the telescope and he wanted to improve it.
Galileo discovered that between the moons night and day sides the top was sometimes irregular and sometimes the bottom was smooth. He realized the irregularities were because the mountains on the moon.
The diameter of Venus is only 12,103 km, while the diameter of Jupiter is 142,984 km. And so when you compare the two planets, Jupiter is 11.8 times bigger than Venus.
Jupiter is far bigger than Venus. In fact, Jupiter is the largest planet in the solar system. However, because Venus is closer to the sun and closer to the Earth, it shines more brightly than Jupiter does.
It was his observation of four of the moons of Jupiter.
Well, Some of the astronomical things that he observed are: the phases of Venus. the craters on the Moon .Jupiter's orbiting moons
When Galileo observed that there are satellites which orbit the planet Jupiter, this was clear evidence that not everything orbits the Earth.
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
Galileo's observations of the gibbous phase of Venus proved that the Sun was the center of the Solar System, with the planets revolving around it. This disproved the prevailing theory of the time that the planets orbited around the Earth.
He thinks that Galileo was Venus and Jupiter
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.
The phases of the planet Venus are the different variations of lighting seen on the planet's surface
Galileo discovered two important things: the moons of Jupiter and the phases of venus. Both discoveries raised doubts about the old Ptolemaic system which was geocentric, and the phases of Venus showed that it was definitely wrong. But neither discovery proved that Copernicus's theory - supported by Galileo - was right. This is because Tycho's geocentric system explained the phases of Venus satisfactorily.
Seventeenth-century astronomer Galileo Galilei.
Jupiter
Galileo discovered sunspots in 1612. He also discovered the phases of Venus and four of Jupiter's moons during his lifetime.
