SETI Revises Alien Contact Protocols Amid Rising Fascination With 3I/ATLAS — Strange Timing Indeed - USA Herald

Key Insights In a move raising questions about transparency and control, the International Academy of Astronautics’ SETI Committee has released a new scientific paper of its post-detection protocols—fifteen years after the last update—redefining who can communicate with potential extraterrestrial intelligence. The revised framework, submitted on October 16, 2025, effectively centralizes post-detection communication authority to a SETI’s new protocols centralize alien communication authority among select scientists and agencies as 3I/ATLAS draws global attention.
