16. Where should we put our telescopes? 1. Mountain tops above atmospheric haze. Reduces the twinkle effect and distortion. 2. Far from city lights ( light pollution). 3. If our atmosphere blocks the wavelength needed to study, then the scope goes into orbit!
35. Gamma Rays These telescopes are looking for high energy events: black holes, neutron stars and quasars. Due to their high energy content, Gamma rays are able to cause serious damage when absorbed by living cells. Gamma rays are also able to penetrate dense materials. Aren’t we glad our atmosphere blocks them!
36. The Compton Gamma Ray Observatory orbits the Earth, detecting high-energy photons – GAMMA RAYS
