SETI Institute Tracks ‘Twinkling’ Pulsar Signals to Sharpen Cosmic Clocks and Hunt for Alien Signals

A year-long SETI Institute investigation into a flickering pulsar has revealed how radio waves warp as they travel through deep space, offering a powerful new tool for distinguishing natural cosmic noise from potential alien transmissions. During the observational period, the SETI Institute closely monitored pulsar PSR J0332+5434 (also known as B0329+54) to study how its radio signal “twinkles” as it passes through interstellar gas. Using the Al…
