First Light

First light (astronomy)

In astronomy, first light is the first use of a new instrument, typically a telescope, to take an astronomical image after it has been constructed. This is often not the first viewing using the telescope, as optical tests are usually performed beforehand to adjust the components.

Chronology of the universe

The chronology of the universe describes the history and future of the universe according to the current understanding of physical cosmology. In this model, the earliest stage that is supported by observational evidence is known as inflation, which occurred 13.8 billion years ago. During this epoch, space underwent a period of extremely rapid expansion in a tiny fraction of a second. Once inflation ended, the energy that was responsible for it was converted into particles and radiation, heating up the universe into a very hot and dense state, initiating the Big Bang.

Light

Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometers (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared and the ultraviolet, called collectively optical radiation.
