Mirrors,
The Hubble space telescope first had one big shaped mirror, which made the images blury so they sent up astronaughts and replaced it with 4 8.2 meter flat mirrors making the pictures more clear!

Who spotted Jupiter's four largest moon?
the cridit goes to Galileo who discoverded it with his won telescope which he invented.
Why was the four largest satellites of Jupiter discovered?
Because someone - Galileo Galilei - looked through the new wonder tool - the telescope - and saw four - he thought they were stars at first - but later realised they were moons of Jupiter.
What was two discovers that Galileo was able to make by using his telescope to study objects in the sky?
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
What are Jupiter's four big moons named?
The four largest moons of Jupiter are called the Galilean satellites, because they were discovered by Galileo when he first observed Jupiter with a telescope. Their names are: * Io * Europa * Callisto * Ganymede
Why did they invented the telescope?
The telescope was introduced to astronomy in 1609 by the great Italian scientistGalileo Galilee, who became the first man to see the craters of the moon, and who went on to discover sunspots, the four large moons of Jupiter, and the rings of Saturn. Galileo's telescope was similar to a pair of opera glasses in that it used an arrangement of glass lenses to magnify objects. This arrangement provided limited magnifications to 30 times for Galileo and a narrow field of view; Galileo could see no more than a quarter of the moon's face without repositioning his telescope.
Today the largest optical telescope has four 8.2 meter what?
reflectors
When did Galileo introduce the telescope to the world?
because he wanted to show the four largest moon
Who spotted Jupiter's four largest moon?

What 2 discoveries Galileo make using a telescope?
He discovered that Saturn has rings and he discovered Jupiter's four largest moons.

What is ganymaede?
In Roman myths and legends, Ganymede was one of the many lovers of the chief god Jupiter. On first observing the four largest moons of Jupiter, Galileo gave the name Ganymede to the largest of them. (There are actually dozens of moons of Jupiter, but Galileo's telescope was only big enough to see the largest four.)

Which planet has the Galilean moons orbiting around it?
Jupiter. The "Galilean" moons are the four largest moons, which are so large that Galileo was able to see them orbiting Jupiter even with his relatively modest telescope.
What was two discovers that Galileo was able to make by using his telescope to study objects in the sky?
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
Describe planets that orbit Jupiter?
No planets orbit Jupiter. Jupiter is orbited by more than 60 moons, however. The four largest are visible from earth through a modest telescope. These four are known as the Galilean moons, as they were observed by Galileo 400 years ago. The largest of the four is Ganymede, a moon that is larger than the planet Mercury (though perhaps not quite as massive).
