saturn
The rings ofSaturn were discovered in the year of 1610 by a man named Galileo. He was the first to observe the planet though a telescope. At first, because of the tilt of the rings, he thought the planet had "ears". But he was a careful and consistent observer. He soon realized that what he was seeing was a ring . Saturn itself has been observed since ancient times.
Galileo had a theory, it was that the earth was NOT in the centre of the solar system like everyone thought, he made the first telescope and proved everyone wrong by looking into space and seeing that the sun was in the centre of the solar system, not the earth, doing this he also invented the telescope.
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
He was the first to see Jupiter's four largest moons: Ganymede, Callisto, Europa and Io.These four are now called the Galilean moons in his honor.
I assume there is life other than ours on other planets, but seeing as we can only go so far with technology, satellites and astronauts, we have not found a 'parallel universe' or 'aliens' yet. Life on other planet would not be so close to Earth, so we will keep looking and hopefully one day find life on other planets. To directly answer your question, there are no other continents or countries on other planets because we have not discovered any new planets recently or advanced life on a planet, solar system or galaxy other than ours. Other planets with civilization may be trillions and trillions and trillions of light years away.

Galileo Galilei first recorded seeing three "stars" in 1610 January, and thought they were simply fixed stars behind Jupiter. Later that year he observed a fourth star, and also concluded that they were orbiting Jupiter.

Currently no planet other than Earth is known to harbor life. Even then, the planets outside our solar system are so distant that we would have no way of seeing what that life looked like.

We can look for it by using these tecniqes. •Seeing it in rocks (meteorites) •Seeing it gravitationally •Seeing it spectroscopically (remote sensing) •Seeing morphological features of it (remote sensing) •Seeing it (remote sensing)
There are two basic ways to locate a planet orbiting another star.The first is by detecting the slight wobble of the star that is created by the gravitational pull of the planet as it orbits the star. This type of test is better at locating large planets that are close to their parent star seeing as how planets invariably have much less mass, and therefore have very little affect on the star itself. The second method is to simply look at the light coming directly from the star and wait for it to dim. This happens when an orbiting planet passes between the star and earth, essentially creating an "eclipse" type effect.

Galileo discovered Jupiter moons in 1610 and reported seeing mountains.
