ESO's VISTA telescope has been trained on the same patch of sky repeatedly to slowly accumulate the very dim light of the most distant galaxies. In total more than six thousand separate exposures with a total effective exposure time of 55 hours, taken through five different colored filters, have been combined to create this picture. This image from the UltraVISTA survey is the deepest infrared view of the sky of its size ever taken.
