World's biggest digital camera to join asteroid search - space - 04 September 2007 - New Scientist Space: "The world's largest digital camera has been installed on a new telescope designed to hunt for potentially dangerous asteroids. The camera was installed on the PS1 telescope in Maui, Hawaii, US, the first of four telescopes being built as part of a project called the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). Pan-STARRS will make frequent scans of the sky, searching for asteroids that could pose an impact threat to Earth (see New telescope will hunt dangerous asteroids). Typical consumer digital cameras offer imaging chips just a few millimetres across. The new Pan-STARRS camera, by contrast, boasts a light-detecting surface that spans 40 centimetres. Sixty separate chips lie on that surface, providing a total of 1.4 billion pixels."
