Calling Planet X

Filed under: Science — bblackmoor @ 14:44

Over the past 20 years, huge swaths of the sky have been searched for slowly moving bodies, and well over 1000 KBOs found. But these wide-area surveys can spot only large, bright objects; longer-exposure surveys that can find smaller, dimmer objects cover only small areas of the sky. A Mars-sized object at a distance of, say, 100 AU would be so faint that it could easily have escaped detection.

That could soon change. In December 2008, the first prototype of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) was brought into service at the Haleakala observatory on Maui, Hawaii. Soon, four telescopes – equipped with the world’s largest digital cameras, at 1.4 billion pixels apiece – will search the skies for anything that blinks or moves. Its main purpose is to look out for potentially hazardous asteroids bound for Earth, but inhabitants of the outer solar system will not escape its all-seeing eyes.
