The HUDF is an image of a small region of space in the Fornax constellation, believed to contain an estimated 10,000 galaxies.
Researchers at the Instituto de Astrofísica de Canarias (IAC), based in the Canary Islands, have processed a composite of several Hubble images to unveil a revised image of the Universe.
The IAC researchers said: “Recovering this light, emitted by the stars in these outer zones, was equivalent to recovering the light from a complete galaxy.”
Alejandro Borlaff, the IAC team’s project leader, said: “What we have done is to go back to the archive of the original images, directly as observed by Hubble, and improve the process of combination.
