The Arecibo Message was a brief binary-encoded message sent into space from the Arecibo Observatory on November 16, 1974, to demonstrate human technological achievement. In mid-2020, the Arecibo Observatory selected a new message designed by students. The Arecibo Telescope collapsed in late 2020, and the message was never sent.
The Planetary Habitability Laboratory (PHL) is commemorating the 50th anniversary of the Arecibo Message with the event "The Last Arecibo Message" in November 2024. This event celebrates the legacy of the Arecibo Observatory and a look toward the future of interstellar communication.
