Scientists at the SLAC National Accelerator Laboratory have spent the past seven years working on the Legacy Survey of Space and Time (LSST), a camera as large as a small car and the proud holder of the world’s largest lens title by the Guinness World Records. At long last, they can, quite literally, see the big picture as the camera is close to completion.
Evidently, the LSST wasn’t a snap to make. The almighty 3,200-megapixel camera stands at five feet and five inches, and boasts a five-foot-two lens as well as a 23.6-inch focal lens. According to CNET, the tool will capably detect a golf ball from 15 miles away.
So close we can almost taste it.....okay, please don't lick the camera.

When complete, it will be able to map the sky at seven times the width of the full moon every 15 seconds from its new home at the Vera C. Rubin Observatory in the Chilean mountains, eventually creating a 3D film of the complete southern sky. Importantly, the camera will be used to help scientists understand dark energy and dark matter better.
In its lifetime, the LSST camera will have the potential to uncover 17 billion new stars, along with six million celestial objects from our solar system.
The team’s last touch for the camera before transporting it to Chile will be to update its refrigerating technology so that the equipment can be cooled down to -100°C (-148°F) when its engines are running too noisily.
The camera will then make its journey to the mountains, first via a chartered Boeing 747 flight, and then on a train that passes through the Cerro Pachón mountain, in May 2023.
