New message Arecibo updates original attempt to contact ET


All this was packaged and on November 16, 1974, directed to the star cluster M13. As interesting as the experiment was, the project was not exactly a serious attempt to make contact. After all, the M13 is 25,000 light-years away – meaning that any potential response would not reach for at least 50,000 years – and when the signal arrives, the cluster may not even be in the right position anymore.
