  1. In modern cameras, the term CCD stands for Close Coupled Device. This technology was first modernized and fitted to the Hubble Space Telescope. Imagine an ice-cube tray. The individual pockets of the tray are struck by light particles, or photons, and the tray is allowed to capture photons for a period of time. Information gathered by the collisions included velocity, frequency, and mass. Occasionally, images require many hours or even days to capture enough particles to render an image of the most distant stars. After a period of time, the individual cube pockets were counted, inventoried, and the information for each cube was transmitted to the ground and a 256-levels of gray image would result. Many years later, the Hubble cameras were upgraded, but the CCD has changed little. It is made of a particular type of stone. a very thin slice of stone. Since stone is made up of crystal, and those particles of stone are micro-scopic, the ability to count so many tiny cube-pockets will give us wonderful images. I can think of one issue that might be a problem. Even at a transmission burst-speed of 5-Gig per second, those images will take hours to beam down to us, and the telescopes orbit rather quickly. I’d guess a couple days download for each image. Ain’t science grand?
