Beacon in the Galaxy: NASA's Proposal for an Interstellar Greeting to the Galactic Center

To the point

NASA scientists, inspired by Carl Sagan, propose beaming a Beacon in the Galaxy interstellar message to the dense ring of stars near the Galactic Center that would spell out simple rules for communication, basic math and physics, DNA components, and information about humanity with a return address, to be sent from facilities such as the Allen Telescope Array and FAST, a plan led by Dr Jonathan Jiang that weighs Stephen Hawking’s cautions and Anders Sandberg’s risk–benefit view while aiming to spark global coordination and possible learning from any reply.
