admin The Legacy Survey of Space and Time (LSST) Camera is now complete. It will soon travel to the Vera C. Rubin Observatory where it will provide an incredible new eye on the southern sky and help us better answer fundamental questions about the nature of dark matter and dark energy.
The LSST camera is a technical marvel. It is 3,200 megapixels and it weighs 3,000 kilograms (6,600 pounds). The images produced by the camera are so large that to screen them properly it would take 378 4K ultra-high-definition televisions in a grid to screen them properly. What a device!
“With the completion of the unique LSST Camera at SLAC and its imminent integration with the rest of Rubin Observatory systems in Chile, we will soon start producing the greatest movie of all time and the most informative map of the night sky ever assembled,” Director of Rubin Observatory Construction and University of Washington professor Željko Ivezić, said in a statement.
