“These two instruments will just rewrite radio astronomy,” Perley predicts. Other new, somewhat smaller projects—such as the Low Frequency Array in Europe and the Allen Telescope Array in northern California—also promise to help brighten the future for radio astronomy. “It’s very hard to predict precisely the science that will come from these things,” Perley says. “The best stuff is the stuff you don’t anticipate.” Karl Jansky, who himself made a huge contribution to science through serendipity, would no doubt agree.
