Hubble Paints Picture of the Evolving Universe
Ultraviolet light adds missing piece to cosmic puzzle
Our team has assembled one of the most comprehensive portraits yet of the universe’s evolutionary history, based on a broad spectrum of observations by the Hubble Space Telescope and other space and ground-based telescopes. Our program, called the Hubble Deep UV (HDUV) Legacy Survey, extends and builds on the previous Hubble multi-wavelength data in the CANDELS-Deep (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey) fields within the central part of the GOODS (The Great Observatories Origins Deep Survey) fields.
The addition of these ultraviolet images opens a new window on the evolving universe, tracking the birth of stars over the last 11 billion years back to the cosmos’ busiest star-forming period, about 3 billion years after the big bang. The color image below is only a very small portion of the full dataset, which encompasses a sea of approximately 15,000 galaxies — 12,000 of which are star-forming — widely distributed in time and space.
We have made all the images of the HDUV survey publicly available to the community as high-level science products here.
