Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric 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.
Somatic cells go through four phases of mitosis: prophase, metaphase, anaphase, and telophase. The entire process typically lasts about 1-2 hours in most mammalian cells.
Galileo's telescopic observations of the 4 large moons of Jupiter and the phases of Venus helped support the heliocentric model of the solar system developed by Copernicus. Copernicus predicted that all phases would be visible since the orbit of Venus around the Sun would cause its illuminated hemisphere to face the Earth when it was on the opposite side of the Sun and to face away from the Earth when it was on the Earth-side of the Sun. In contrast, the geocentric model of Ptolemy predicted that only crescent and new phases would be seen since Venus was thought to remain between the Sun and Earth during its orbit around the Earth. Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric model.
every 29.53 days
Yes
8 phases.
From the perspective of the earth, the most apparent objects that go through phases are the moon, Venus and Mercury
Yes. Mercury and Venus have phases. We can't really observe phases for the outer planets, because we always see the bright side, since we are on the same side as the Sun. Any asteroid that gets near enough could also have phases.
All of the planets show "phases", in which only part of the planet is illuminated. However, only Venus and Mercury, as "interior" planets, go through the complete new/crescent/gibbous/full cycle.
The changes in shape that the moon goes through are called phases.
It takes 29.5 days for the moonto go through all the phases - from full moon to full moon. :)

Only partly. We never see Mars in a crescent or new phase, just the full and gibbous phases. That's because Mars is farther away from the Sun than the Earth is, so we never see it "inside" our orbit. On the other hand, we see the crescent and gibbous phases of the planet Venus, but never the full or new phases, because when Venus would be "new", it's too close to the Sun to be observed - and when Venus would be "full", it's on the other side of the Sun, and not visible!
children go through a destructive phase at young ages.
Fire ants go through many phases of metamorphosis. They go through egg, larva, and pupa stages before they reach adulthood.
The phases of Venus in the heliocentric model of the solar system provide evidence that supports the idea that the Earth orbits the Sun. As Venus goes through its phases, from crescent to full and back to crescent, it demonstrates that Venus revolves around the Sun and not the Earth. This observation helped to confirm the heliocentric model proposed by Copernicus, which states that the Sun is at the center of the solar system and the planets, including Earth, orbit around it.
It takes one month for the Moon to go through all of its phases one time.
