Spotting scope - A small refractor to line up the big scope. Eyepiece for viewing Today’s refractor
Mount Palomar Observatory Hale Telescope Inside Mt. Palomar Observatory Large telescopes are put in observatories to protect them.
Other scopes at Palomar Look across the mountain tops!
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!
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!
The Compton Gamma Ray Observatory orbits the Earth, detecting high-energy photons – GAMMA RAYS
The spectroscope Takes light from stars and analyzes it.
Light from a star or other source goes through the slit.
Every element has a different set of spectrum lines. Much like people having different fingerprints.
