List of interstellar radio messages
(Redirected from Interstellar radio message)
Template:SHORTDESC: This is a list of notable interstellar radio messages (IRMs) transmitted from Earth. Many of these were sent in the aim of searching for extra-terrestrial intelligence (SETI), and are often called 'active SETI' or 'METI' (Messages to Extra-Terrestrial Intelligence) projects.
