Arecibo Observatory Data Helps SETI Uncover Secrets of Pulsar Signals and Cosmic Distortions

Data from the now-collapsed Arecibo Observatory continues to drive major discoveries in space science. Sofia Sheikh and her team from the SETI Institute utilised archived data to investigate the signals of pulsars—dense neutron stars emitting radiation like cosmic lighthouses. Their study focused on how these signals are distorted by interstellar gas and dust, a phe...
