World's largest radio telescope: A supercomputer will link, 10,000 antennas to create a window on the early universe

摘要

WHETHER it's a simple 3-in. refractor aimed at the craters of the moon or the USD3 billion Hubble Space Telescope searching the sky for unseen galaxies, the telescope is the closest thing we have to a time machine. It is not the sort of science fiction device that lets us journey back to the age of the dinosaur, of course. But because even light takes time to travel, the deeper into space we stare, the more ancient the image we perceive.
