By the top of the survey, this 3.2-gigapixel digicam could have catalogued 20 billion galaxies and picked up as much as 60 petabytes of knowledge—roughly 3 times the quantity at present saved by the US Library of Congress. Compiling all these photos collectively, with assist from specialised algorithms and a supercomputer, will give astronomers a time-lapse view of the sky. Seeing how so many galaxies are dispersed and formed will allow them to review darkish matter’s gravitational impact. Additionally they plan to create probably the most detailed three-dimensional map of our Milky Means galaxy ever made.
If all goes nicely, the telescope will snap its first science-quality photos—a particular second generally known as first mild—in mid-2025. The general public might see the primary picture launched from Rubin quickly after.
