This color image shows the Hubble Ultra Deep Field region, a tiny but much-studied region in the constellation of Fornax, as observed with the MUSE instrument on ESO’s Very Large Telescope. But this picture only gives a very partial view of the riches of the MUSE data, which also provide a spectrum for each pixel in the picture. This data set has allowed astronomers not only to measure distances for far more of these galaxies than before — a total of 1600 — but also to find out much more about each of them. Surprisingly 72 new galaxies were found that had eluded deep imaging with the NASA/ESA Hubble Space Telescope. | ESO/MUSE HUDF collaboration

This Is the Deepest View Into the Universe That Has Ever Been Seen

The Very Large Telescope in Chile has taken the deepest spectroscopic survey of space ever, with astronomers focusing on the Hubble Ultra Deep Field.

This compound image shows the Hubble Ultra Deep Field region and highlights in blue the glowing haloes of gas around many distant galaxies discovered using the MUSE instrument on ESO's Very Large Telescope in Chile. The discovery of so many huge haloes, which radiate ultraviolet Lyma-alpha radiation, around many distant galaxies is one of the many results coming out of this very deep spectroscopic survey. | ESO/MUSE HUDF team
