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.
Galileo, who struggled against the Catholic Church to have the theories of Copernicus accepted.
I believe that was Aristotle. This would be a geocentric universe. Galileo however, knew the universe was heliocentric and was persecuted for it.
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.

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.
Galileo did not discover Saturn. It was know of by the ancients. It can be seen at certain time without the aid of instruments.
nope
yes Galileo Galilie discovered Saturn
Galileo discovered Saturn's Rings in 1610
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 did not actually discover space. Space was studied by prehistorical astronomers back into the days of Egypt and Maya, and possibly further back into history.But between 1592 and 1610, Galileo devoted most of his time to studies of the universe, and in 1610 is when he first revealed publicly his belief that the Earth actually rotated around the sun (heliocentric) as opposed to the previous Earth-centered universe (geocentric).
Galileo's greatest discovery was the discovery of jupiter's moons and rings.
