MORE ABOUT TELESCOPES . . .

Inventors often get ideas from other inventors. That may have been the case with Galileo. Hans Lippershey made glasses. He found that you could make objects appear closer by putting two lenses together inside a tube. Telescopes help us see objects that are very far away. Of course, the telescope has changed a lot since the days of Galileo and Lippershey. Many others, including Sir Issac Newton who discovered gravity, made improvements to the telescope. Scientists and astronauts use telescopes to see objects in the universe. Do you know how far away an object can be seen with a modern telescope? Use your information detective skills to find out!
