Hunting For Galaxies - a photo on Flickriver

            This panoramic view was captured during an observing run of the 4-meter Victor M. Blanco Telescope (left) located at Cerro Tololo Observatory in the Chilean Andes. This telescope (funded by NSF 's NOIRLab) has helped astronomers to prove the acceleration of the cosmic expansion in 1998 by looking at distant supernovae! 

💡Now, the Blanco telescope is studying the population of thousand of galaxies in the Universe and especially how dark energy is influencing them. For that mission, it is equipped with an astonishingly resolved CCD camera of 570 megapixels! A single 90 seconds photograph, that covers a region of the sky as wide as 8 full moons, can reveal up to 150,000 galaxies! This high-end imaging instrument is called #DECam - Dark Energy Camera - and was used during 758 nights between 2013 and 2019 as part of the Dark Energy Survey.

I took this photo in August 2018, when the survey was still being completed.
