SETI's Breakthrough with Cosmic Lighthouses from a Ruined Observatory

Using data from the now-collapsed Arecibo radio telescope, SETI scientists have studied how pulsar signals are distorted by the interstellar medium, revealing that current models of the universe may need revision. This research, led by Sofia Sheikh, highlights the importance of archived data and its role in understanding cosmic phenomena like gravitational waves. The findings suggest that galactic structures, such as the Milky Way's spiral arms, influence these distortions, which could refine gravitational wave detection methods.
