Over the past few months I had the privilege to be part of a team of artists and researchers who assembled a hypothetical message from ET for A Sign in Space, a project founded and directed by media artist Daniela de Paulis.
The message was loaded on the ExoMars Trace Gas Orbiter, a spacecraft orbiting Mars. On May 24th it was beamed back to Earth and received by several radio telescopes during a live performance.
Since then, a community of people from all walks of life has been attempting to make sense of the message. If you enjoy the challenge, join the discord channel https://discord.com/channels/1066055437457297469/11114043296... and give it a try!
