The Cosmic DAWN Survey is a new project that helps us peer into the distant past, uncovering the secrets of the first galaxies. By combining data from the Euclid Space Telescope with observations across ultraviolet, visible, and infrared wavelengths, this survey provides an unprecedented look at how galaxies formed and evolved over cosmic time.
Covering 59 square degrees of sky, DAWN allows scientists to study some of the earliest galaxies—those that existed when the universe was less than a billion years old. It helps answer fundamental questions about the birth of galaxies, the role of dark matter, and how the cosmos was shaped by the mysterious process of reionization.
By mapping the faintest and most distant galaxies, the DAWN Survey is expanding our understanding of the universe’s origins and setting the stage for future discoveries.
