In recent months, Mexico and Chile have faced the launch of their bid to build the LSST telescope in their territory. Well, Chile has imposed itself on the party, so the precious telescope will be built at the observatory of Cerro Totolo at a height of 2,640 meters. Thanks to a telescope of 8.4 meters of lens opening, for three days you will take a picture of the whole sky visible. With the current telescopes, years are needed to carry out this process.
