If there are space invaders out there, it won't be long before they can no longer stage a sneak attack, thanks to a project to build the most sensitive radio telescope ever -- one that's the size of a continent. Known as The Square Kilometer Array (SKA), it will explore the universe, identify any potential alien threats to our planet and hopefully answer some fundamental questions from astronomers. Its thousands of receptors, spaced roughly one kilometer apart, will be linked across an entire continent. They'll be arranged in five spiral arms like a galaxy, 3,000 50-foot-wide dishes that extend out from a central core at least 1,860 miles (3,000 kilometers) -- about the distance from New York City to Albuquerque, N.M. The board of directors behind the telescope met for the first time in late January to kick off the project. Their first decision: where to house such a beast. After all, if it's located in Australia, the antennas could span the entire continent. If it's in South Africa, another location being considered, they would stretch to the Indian Ocean islands. Optical telescopes can reveal only so much of the universe. The SKA's radio telescopes, on the other hand, pick up radio-frequency signals unobscured by, say, cosmic dust. They will survey the sky 10,000 times faster than any other telescope and with 50 times the sensitivity and 100 times the survey speed of current imaging instruments. Among the SKA's missions: finding an answer to the question, "Are we alone?"
