Astronomers used the Green Bank Telescope to search interstellar comet 3I/ATLAS for signs of extraterrestrial technology but found no technosignatures, confirming it is a natural comet and not an alien spacecraft. The study highlights the importance of continued searches for interstellar objects that might harbor technological signals in the future.
The MeerKAT radio telescope in South Africa is preparing for a second observation window as 3I/ATLAS approaches its closest point to Earth on December 19, with the potential to detect signals that could indicate extraterrestrial intelligence, raising profound scientific and societal questions.
Researchers have achieved a groundbreaking 20-minute interaction with a humpback whale using AI to decode and replicate its complex vocalizations, revealing language-like structures and raising implications for understanding animal intelligence and extraterrestrial communication, while also prompting ethical considerations in human-animal interactions.
The SETI Institute, the National Radio Astronomy Observatory, and the Breakthrough Listen Initiative have teamed up for a new project called COSMIC, which uses the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to search for signals from other galactic civilizations. The VLA is collecting data that scientists will analyze for the type of emissions that only artificial transmitters make, signals that would betray the existence of a technically accomplished society. The new processing system for SETI is dubbed “COSMIC” – the Commensal Open-Source Multimode Interferometer Cluster – and is spearheaded by the SETI Institute, in collaboration with the National Radio Astronomy Observatory and the Breakthrough Listen Initiative.
