The largest digital camera ever created will soon capture the deep universe

IN the largest digital camera in the world getting ready to to be installed at the Vera Rubin Observatory on a Chilean mountain peak. Once completed, the project will depict half of the southern sky every three days, peering into the elusive deep universe.

“The Hereditary Space and Time Survey (LSST) is a planned 10-year study of the southern sky that will take place at the Vera C. Rubin Observatory, which is currently being built on Mount El Penon on Cerro Pashon in northern Chile. The survey data will allow researchers around the world to better assess a wide range of pressing questions about the attributes of dark energy and dark matter, the formation of the Milky Way, the properties of small bodies in the solar system, the trajectories of potentially dangerous asteroids, and the possible existence of undetected explosive phenomena “, reads a statement from Stanford University.

The LSST is a 3.2-gigapixel (3.2 billion pixels) camera that will be able to look very far into the distance (and therefore past) in the sky and depict a much wider region than ever before. The weekly portraits by LSST will form the Space and Time Heritage Survey, a 10-year project to uncover what our many distant universes have hidden so far.

The LSST chamber consists of six rotating optical filters that can be turned on and off according to what astronomers are trying to capture and the light conditions of the night. The filters provide the ability to display the sky in six different bands of the electromagnetic spectrum.

LSST will explore as much of the sky as possible and track how it changes to understand both the nature of distant galaxies and the events of our past history. It will also monitor near-Earth asteroids, making sure they do not collide with our planet.
