. This view shows some highlights from widest deep view of the sky ever taken using infrared light, with a total effective exposure time of 55 hours. It was created by combining more than 6,000 individual images from the VISTA survey telescope at ESOтАЩs Paranal Observatory in Chile. This picture shows a region of the sky known as the COSMOS field in the constellation Sextans the Sextant. Credit: ESO/UltraVISTA team. Acknowledgement: TERAPIX/CNRS/INSU/CASU
