Even after its collapse, data from the Arecibo radio telescope continues to yield groundbreaking discoveries. Scientists have used archived data to study the distortions of pulsar signals, revealing new insights into the interstellar medium and improving our ability to detect gravitational waves.
In a groundbreaking event, a coded message beamed to Earth from Mars by the ExoMars Trace Gas Orbiter has been deciphered by a father-daughter team. This ‘alien signal,’ part of an art project called ‘A Sign in Space,’ reveals images of five amino acids, raising intriguing questions about its meaning and the potential for extraterrestrial communication.
Swan Hellenic, renowned for its cultural expedition cruises, is venturing into the cosmos with its new ‘Explore Space at Sea’ series. In partnership with the SETI Institute, this groundbreaking initiative offers travelers a unique opportunity to delve into the mysteries of astronomy, astrophysics, and the search for extraterrestrial life, all while enjoying breathtaking ocean voyages. Renowned SETI scientists will lead lectures and discussions, providing insights into cutting-edge discoveries and captivating guests with their expertise.
A new study proposes that the mysterious ‘Wow! signal’, once thought to be a possible alien broadcast, could be the result of a rare cosmic event involving a magnetar and a hydrogen cloud. This explanation is supported by the discovery of similar signals in archival data from the Arecibo Observatory.
A recent search for extraterrestrial signals using the Murchison Widefield Array (MWA) in Australia, focused on 1,317 galaxies in the constellation Vela, yielded no detections. However, the study provides valuable constraints on the power of potential alien transmitters, suggesting that any civilization capable of sending signals strong enough for us to detect would need to harness the power of a star or multiple stars. This null detection further emphasizes the vastness of the search space and the need for continued exploration across a wide range of frequencies.
