SLAC/Rubin: World's Largest Digital Camera Snaps First Images

Sensors of World’s Largest Digital Camera
Snap First 3,200-Megapixel Images at SLAC

SLAC National Accelerator Laboratory | Vera C. Rubin Observatory | 2020 Sep 08

Crews at the Department of Energy’s SLAC National Accelerator Laboratory have taken the first 3,200-megapixel digital photos – the largest ever taken in a single shot – with an extraordinary array of imaging sensors that will become the heart and soul of the future camera of Vera C. Rubin Observatory.

The images are so large that it would take 378 4K ultra-high-definition TV screens to display one of them in full size, and their resolution is so high that you could see a golf ball from about 15 miles away. These and other properties will soon drive unprecedented astrophysical research.

Next, the sensor array will be integrated into the world’s largest digital camera, currently under construction at SLAC. Once installed at Rubin Observatory in Chile, the camera will produce panoramic images of the complete Southern sky – one panorama every few nights for 10 years.

Its data will feed into the Rubin Observatory Legacy Survey of Space and Time (LSST) – a catalog of more galaxies than there are living people on Earth and of the motions of countless astrophysical objects. Using the LSST Camera, the observatory will create the largest astronomical movie of all time and shed light on some of the biggest mysteries of the universe, including dark matter and dark energy. ...
Know the quiet place within your heart and touch the rainbow of possibility; be
alive to the gentle breeze of communication, and please stop being such a jerk.

Let's hope that the growing swarms of low orbit communication satellite constellations won't hamper this Observatory from achieving it's ambitious objectives.
Just as zero is not equal to infinity, everything coming from nothing is illogical.

We'll always have the Harvard College Observatory plates. If those communication satellite constellations leave the ground and you don't have those 500,000 glass plates digitized, you'll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.

<<Over 500,000 glass plates held by the Harvard College Observatory are to be digitized. From 1885 until 1992, the Harvard College Observatory repeatedly photographed the night sky using observatories in both the northern and southern hemispheres. Over half a million glass photographic plates are stored in the observatory archives providing a unique resource to astronomers. The Harvard collection is over three times the size of the next largest collection of astronomical photographic plates and is almost a quarter of all known photographic images of the sky on glass plates. The scope of the Harvard plate collection is unique in that it covers the entire sky for a very long period of time.>>
