This image from the Hubble Deep UV (HDUV) Legacy Survey encompasses 12,000 star-forming galaxies in a part of the constellation Fornax known as the GOODS-South field. With the addition of ultraviolet light imagery, astronomers using the NASA/ESA Hubble Space Telescope have captured the largest panoramic view of the fire and fury of star birth in the distant universe.
Hubble’s ultraviolet vision opens up a new window on the evolving universe, tracking the birth of stars over the last 11 billion years up to the busiest star-forming period in the cosmos, which happened about three billion years after the big bang.
So far, ultraviolet light has been the missing piece of the cosmic puzzle. Now, combined with data in infrared and visible light from Hubble and other space- and ground-based telescopes, astronomers have assembled the most comprehensive portrait yet of the universe’s evolutionary history. The image straddles the gap between the very distant galaxies, which can only be viewed in infrared light, and closer galaxies, which can be seen across different wavelengths. The light from distant star-forming regions in remote galaxies started out as ultraviolet, but the expansion of the universe has shifted the light into infrared ...
