From Earth to the Universe
When Galileo turned his telescope to the sky 400 years ago, he was using a tool to enhance his natural vision. This so-called visible, or optical, light that Galileo observed represents just a mere slice of the entire spectrum of light we now know radiates across the Universe.
Today, astronomers have built telescopes and detectors that can see far beyond the type of radiation we can detect with the human eye. Ranging from long radio and infrared waves to shorter wavelengths of ultraviolet, X-rays, and gamma rays that reveal the hottest parts of the Universe, modern astronomy is really one of telescopic diversity. All of these new tools allow views of the cosmos that Galileo most likely could never have imagined.
