Digital Upgrades for a Radio Astronomy Revolution

Using more sophisticated computers and electronics will vastly increase the resolution, sensitivity and data capacity of the Very Large Array telescope

“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.

    It is interesting that no mention of "The Big Ear" that John Kraus (OSU) designed and constructed, was made. The tremendous contributions his findings made to the radio maping of the universe should not have been ignored.
