Cosmic Call was the name of two sets of interstellar radio messages that were sent from RT-70 in Yevpatoria in 1999 (Cosmic Call 1) and 2003 (Cosmic Call 2) to various nearby stars. The messages were designed with noise-resistant format and characters.
Each Cosmic Call 1 session had the following structure. Scientific Part (DDM, BM, AM, and ESM) was sent three times, and Public Part (PP) was sent once, according to the following arrangement:
where DDM is Dutil-Dumas Message, created by Canadian scientists Yvan Dutil and Stephane Dumas, BM is Braastad Message, AM is Arecibo Message, ESM is Encounter 2001 Staff Message; more details present at Report on Cosmic Call.
Each Cosmic Call 2 session had the following structure:
where DDM2 is modernized DDM, BIG is Bilingual Image Glossary; more details present at Synthesis and Transmission of Cosmic Call 2003 Interstellar Radio Message.
The messages were sent to the following stars:
