AEGIS (astronomy)
Encyclopedia
AEGIS, or the All-Wavelength Extended Groth Strip International Survey, is a multi-wavelength astronomical survey of a patch of the sky with low extinction and zodiacal scattering. The purpose of the survey is to study the physical processes and evolution of galaxies

Galaxy
A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. The word galaxy is derived from the Greek galaxias , literally "milky", a...

Observatories
AEGIS makes use of multiple terrestrial and space based observatories to conduct the survey. These observatories make overlapping scans of the survey area. The primary telescopes are:- Very Large ArrayVery Large ArrayThe Very Large Array is a radio astronomy observatory located on the Plains of San Agustin, between the towns of Magdalena and Datil, some fifty miles west of Socorro, New Mexico, USA...
