How a trick from radio astronomy could help astronomers find Earth-like planets

The wavelengths of radio light are so large that you can’t capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you’d need a radio dish tens of kilometers across. So radio astronomers took a different approach. They used an array of dozens of antennas, each capturing their own signal.
