Just as you thought the megapixel race was coming to an end, someone had to go that little bit higher. The Hyper Suprime-Cam (HSC) is an 870-megapixel beast that was built specifically for Japan's Subaru Telescope which is in Hawaii.
The HSC stands at 8.2m tall, and features 116 separate CCD sensors that are operated at minus 100 degrees Celcius. The HSC includes a huge Wide Field Corrector (WFC) system from Canon, and features seven difference lens elements that help improve the image quality captured by Subaru's main mirror, 16 meters below the telescope itself.
How much does an 870-megapixel weigh? Only 872kg. Mitsubishi have helped out, too, where they built the motor that allows for adjustment as precise as 1-2 microns, or just 1/100th the width of a human hair. All of this work for the HSC helps it take pictures of the sky which will help researchers with dark energy and dark matter research.
Right now, imaging for a survey takes around 16 years, but with this new camera it will be reduced down to just two years.
