  1. Tools for studying space

  2. Refreacting and Reflecting Telescopes • Refracting Telescope: uses lenses to bend or refract light • Invented by Galileo • Magnifies 30 times • Reflecting Telescope: uses a concave mirror and focuses light in front of it • Invented by Isaac Newton

  3. Radio Telescope • Radio Telescope: detects radio waves using big dishes that absorb waves and transmit them to an amplifier • Ex. Very Large Array, New Mexico

  4. Space Telescope • Space Telescope: in orbit around the earth- above atmosphere so produces clearer images of far away objects • Ex. Hubble
