Herschel's Discoveries in Infrared Radiation

The video explores the fascination with stars and highlights Sir Frederick William Herschel's contributions to astronomy, including his discovery of Uranus and infrared radiation. Herschel's experiments on light and heat led to the understanding of the electromagnetic spectrum, revealing types of light invisible to the human eye. The video also discusses how some animals, like rattlesnakes, can detect infrared radiation, and provides an overview of the electromagnetic spectrum, emphasizing the limitations of human vision.
