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.

What anomalies did Galileos first astronomic observations reveal?
Galileo's first astronomical observations revealed several anomalies. He observed that Jupiter had four moons orbiting around it, which challenged the prevailing belief that everything in space revolved around the Earth. He also observed that Venus went through phases similar to the Moon, suggesting that it orbited around the Sun and not the Earth. These observations provided evidence to support the heliocentric model proposed by Copernicus.
What did Galileo discover in the different 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.
What are some of Galileos greatest achievements?
Using inclines, Galileo discovered that all objects fall at the same rate. He was also the first to witness the moons around Venus, proof that the solar system does not revolve around the Earth.
When does Venus have a heliacal rising?
Venus rises heliacaly when reaching arcus visionis between 5.3 and 6.0 degrees. (Arcus visionis is the altitude of the Sun below horizon when Venus is exactly on the horizon). Because Venus is bright and its brightness is stable, the heliacal rise of Venus can be computed easily. Something that cannot be said for the other planets and stars. The last systematic (and published) observations of heliacal risings were made 2000 years ago in Mesopotamia! There are several theoretical algorithms for computing the heliacal phenomena, but none of them is reliable because of the lack of observations. This is soon to be changed. More on the heliacal phenomena, their computation and real first-hand observations can be found by clicking the 'Related link' below.
Galileo's observations of what suggested that the earth moved around the sun Mars Jupiter Venus or Pluto?
It was his observation of four of the moons of Jupiter.

What planet is seen as the same phrases like the moon?
There are none. The planet Venus is often seen in its gibbous and crescent phases, but never appears to be full; when it would be, Venus is hidden behind the Sun. And Venus only appears in the "new" phase twice per century, during the "transits of Venus". The planets Mars, Jupiter and Saturn appear in the gibbous and full phases, but never in the crescent or new phases.
What is the significance of Galileo's observations of the phase of venus?
The phases of the planet Venus are the different variations of lighting seen on the planet's surface
Why did James Cook travel all to Tahiti to observe the transit of venus?
James Cook was hired by the Royal Geographic Society to make scientific observations of the transit of Venus. Tahiti was the best vantage point for these observations.
What were the two observations that Galileo made through the telescope that supported the heliocentric model?
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.
What was Venus discovered with?
Venus has been known as an "evening star" and a "morning star" since antiquity. In the early 17th century, Gallileo Gallilei made closer observations of Venus through a telescope and discovered that Venus had phases, one of the observations that led Gallileo to deduce that the Sun was the center of the Solar System, as opposed to the commonly held belief that the Earth was the center.
What caused Galileo to accept the theory that the planets revolve around the sun?
Amongst many other things, Galileo observed Venus in all four of its phases, crescent, waxing, waning, and full, as well as gibbous transitions between those phases. This proved the Copernican heliocentric viewpoint, making the Ptolemaic model untenable.
What did Galileo discover in the different 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.
What were two observations the Galileo made through his telescope that supported the heliocentric model?
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.
What are some of Galileos greatest achievements?
Using inclines, Galileo discovered that all objects fall at the same rate. He was also the first to witness the moons around Venus, proof that the solar system does not revolve around the Earth.
How did galileos observation of Jupiter and venus support Copernicus's model?
Galileo saw the four largest moons of Jupiter in orbit around the planet, proving that the Ptolemaic system was not simpler - the solar system was not geocentric (the planets and the sun did not orbit around the earth). As far as the observations of Venus go, Galileo saw that Venus displayed phases very much like our moon. Now, according to the Ptolemaic system, Venus could only display a crescent phase because its epicycle put it always in between Earth and the sun. The Copernican system put everything rotating around the sun, and in this way it explained the phases of Venus. Think of it this way, if Venus is always in between the sun and the earth, how can we ever see it completely lit up, like a full moon? The sun is always on the other side of it, so Venus must at some point go on the other side of the sun.
