Read the excerpt from Planets, Moons, and You.
The Hubble telescope was very hard to build because it is so complex. It took some of the best scientists in the world to make it work.
You do not need a gigantic telescope to study our solar system's moons. You can see the features on our moon simply by looking up. It helps to have binoculars or a telescope, especially when looking at the moons of other planets. In fact, some of Jupiter's moons are big enough to see with a pair of binoculars. You might be able to use a larger telescope someday, but until then, you can be an amateur astronomer in your own backyard.
