Pann-Starrs telescope begins operations to hunt asteroids
A new telescope facility in Hawaii designed to search for asteroids and comets which could threaten Earth has been made operational.
The Pan-STARRS 1 telescope will map large portions of the sky each night to track not only close space objects, but also exploding stars (supernovae).
The telescope has been taking science data for six months but is now operating from dusk-dawn each night.
Pan-STARRS 1 (PS1) is expected to map one-sixth of the sky every month.
The facility boasts a huge digital camera: a 1,400 megapixel (1.4 gigapixel) device that can photograph an area of the sky as large as 36 full Moons in a single exposure.
