The big one for the Earth, of course, which everybody sees. But Galileo was the first known person to see the four "galilean" moons of Jupiter; Europa, Callisto, Ganymede and Io. There are another 60 or so moons of Jupiter, but they are all much smaller; far too small to be seen in Galileo's early telescope!

Telescopes have allowed us to see further than the naked eye would ever allow.

Telescopes have also been one of the main reasons that man has begun to explore space, we see things out there worth discovering and taking a closer look at.

Galileo was able to see only Jupiter's largest moons, Io, Europa, Ganymede, and Callisto, because these moons are the largest and brightest of Jupiter's many satellites. Their size and brightness made them visible using the relatively primitive telescope technology available to Galileo in the 17th century. Smaller moons may have been too faint to be seen with his telescopes.
