Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS)
This deep, detailed image is the result of the Hubble Space Telescope’s observations for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). The image displays approximately 30,000 galaxies across 9 billion years of time and space in a fascinating visual study of galaxy evolution. The oldest and most distant galaxies depicted appear red, because as the universe expands their light has been stretched or “redshifted” to longer wavelengths. Red is the longest wavelength our eyes can see; beyond it are longer infrared wavelengths, which some telescopes, including Hubble, can detect for us.
