A lifelong amateur radio enthusiast, Joseph Taylor sends signals via the moon
If the moon is up, there’s a good chance Joseph Taylor is on his ham radio, using a homemade antenna in his backyard to bounce signals off the moon’s pockmarked face. It’s a skill Taylor began cultivating in 2003, shortly before he retired from Princeton University, where he used radio waves to probe the secrets of pulsars, the spinning, magnetized neutron stars that emit bursts of radiation with clocklike regularity.
