Ultraviolet Surveys,pectrum. He found that the effect got stronger towards the violet end of the spectrum and peaked where the radiation was invisible. Ritter’s name for this radiation was Chemical Rays; the term ultraviolet came later.

Gamma Ray Surveys,see Figure 1), and data in some parts of the spectrum are scarce. Because a single gamma ray carries such a lot of energy, there are many fewer of them in the universe than there are, say, radio or infrared photons; every gamma-ray photon that a telescope receives is an individually recorded event.

The CCD Era, (CCD)—a solid-state chip that is capable of capturing images electronically and then feeding them into a computer where they can be stored and analyzed. CCDs, and related devices called C-MOS chips, have completely replaced photographic plates as the technology of choice for recording visible and near-infrared images and spectra.
