Scientists started up the Australia Square Kilometre Array Pathfinder, considered the world's fastest radio telescope, in Western Australia on Friday. ASKAP, which uses 40-foot antennas and cutting-edge "radio cameras," has already been booked for the next five years with scientific researchers around the world. "Radio waves tell us unique things about the cosmos, about the gas from which stars were formed, and about exotic objects, pulsars and quasars, that really push the boundaries of our knowledge of the physical laws in the universe," said ASKAP project director Brian Boyle.
