The Large Synoptic Survey Telescope to be constructed in Chile will incorporate the world’s largest digital camera, capable of recording highly detailed data more quickly than any other telescope of comparable resolution.

For computing specialists, it means more data. A lot more data.
The LSST will take between 1000 and 2000 panoramic 3.2 gigapixel images per night, covering its hemisphere of the sky twice weekly. Along with daytime calibration images, this will amount to 20 terabytes of data stored every 24 hours.
