The twinkling stars that have been a source of wonder to humans for centuries come into sharp focus through the use of everyday telescopes, but with specially built ones, scientists can detect a whole other universe of light waves. In Telescopes, kids are introduced to the electromagnetic spectrum, which includes the gamma rays generated in nuclear power plants and the radio waves that transmit TV signals. Compare refracting and reflecting telescopes, then see them in action in some of the largest structures on Earth, such as the VLA (Very Large Array), which is 22 miles square. But Earth is not the only place you’ll find telescopes; for kids obsessed with Space, coverage of the Hubble Telescope, which has confirmed the existence of black holes, and the finds of other space telescopes will impress to no end.
