About the NEW Arecibo Message

In 2019, to celebrate the 45th anniversary of the iconic Arecibo Message, the Arecibo Observatory (AO) will select updated messages created by inter-generation, diverse and international teams of students. New Arecibo message - the global challenge is an E&PO activity, aiming to engage K-16 students from all over the world in Space related topics, promoting global collaboration and enhancing critical thinking and self-awareness. The challenge seeks for innovative ideas resulting from a global collaborative effort, led by the youth, to define an updated message that would represent the most smart and safe way to say hello to our possible galactic neighbors, promoting the peaceful uses of Space and exploring the cutting-edge technology and scientific knowledge available nowadays.
