1. The electromagnetic thermometer scale featuring Compton, Chandra, Hubble, Spitzer & ALMA.
X-rays are associated with high temperatures of about 10 million to 100 million K. Image (A) features multiwavelength images of the Milky Way. Gamma Ray: CGRO/EGRET; X- Ray: ROSAT/PSPC; Optical: Laustsen et al. Photomosaic; Infrared: IRAS; Radio: Bonn, J.Bank, & Parkes. More information on the Multiwavelength Milky Way. (Credit: NASA/CXC/M.

7. Baseball Field
Imagine if you could see only a tiny sliver of a baseball field. You would never be able to figure out the rules of the game. In the same way, we need x-ray, gamma-ray, ultraviolet, infrared and radio telescopes to cover the full range of wavelengths to get an accurate picture of what is happening in the universe.
