List of interstellar radio messages

Topic: Astronomy

 From HandWiki - Reading time: 5 min
Short description: none

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.

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

Notable transmissions
