OK. Let's say that all times are compressed by a factor of 13 billion. Let's just go right ahead and say that.
Now let's take the high point of Galileo and Kepler to be roughly 500 years ago.
500 years . . . which is 1.5778 x 1010 seconds . . . when compressed by a factor of 13 billion . . .
compresses to 1.214 seconds ago.
Galileo
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.
They believed in a heliocentric universe. This meaning that the earth was not the center of the universe, but that the sun was. However, many people , including the church, did not agree with this theory. Instead they believed in a geocentric universe. Plato and Aristotle believed in this theory.
It didn't - the planet Saturn was observed in ancient times, but Galileo was the first to view it through a telescope and discover its rings in 1610.
Galileo Galilei was forced to admit publicly by the Catholic Church that the Earth stood motionless at the center of the universe in 1633. This was part of the Inquisition's trial against him for supporting the heliocentric model proposed by Copernicus.

In 1620.
Galileo's most significant observation and discovery was that the universe (or now the solar system) was Sun-Centered. Originally, people accepted the Copernican theory that the universe was Earth-centered. For a few years Galileo had to defend his discover until 1616.
No, Venus was already known of in Galileo's time.
nope
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.
yes Galileo Galilie discovered Saturn
galileo
Galileo is famous for observing and proving his heliocentric model of the universe. After his observation the existing model of the universe was slowly phased out.
Galileo's greatest discovery was the discovery of jupiter's moons and rings.

In astronomy, he used a telescope.
