James Webb Space Telescope's Unique Feature
- The James Webb Space Telescope is uniquely positioned a million miles away, opposite the sun, using Earth as a sunblock.
- This positioning offers continuous awareness of the sun's location, crucial for long-exposure photography of dim objects.
Bright Lights in Old Films
- Neil deGrasse Tyson explains why older films used extremely bright lights due to less sensitive film.
- Each frame required significant light, necessitating floodlights for indoor shots, unlike today's adjustable cameras.
Discovery of Infrared Light
- William Herschel discovered infrared light by measuring temperatures of different colors in a light spectrum.
- He found the area next to red had a higher temperature, leading him to posit "light unfit for vision."
