Neil deGrasse Tyson Explains Space Telescopes

How did the first space telescope arrive in orbit? Neil deGrasse Tyson and comic co-host Chuck Nice explore the literal rise of telescopes from Earth into space. You’ll find out what telescopes were called before they were called telescopes. Discover more about early refractive telescopes and their issues with chromatic aberration. Then, you’ll hear how Sir Isaac Newton came in and changed the telescope industry for good by inventing the reflecting telescope. Neil explains why Earth’s atmosphere prevents you from seeing clear images from the ground. Take a trip through the space telescope hall of fame as we discuss the Hubble Space Telescope, the Spitzer Space Telescope, the Chandra X-ray Observatory, the Compton Gamma Ray Observatory, and the soon to be launched James Webb Space Telescope. Lastly, you’ll learn why Hubble might be the most successful science instrument of all time. All that, plus, Neil shares why the different bands of light act as different dialects for the language of the universe.
