“We want to send a message in a bottle in the cosmic ocean, to say, ‘Hey, we are here,'” Jonathan Jiang, an astrophysicist at NASA’s Jet Propulsion Laboratory (JPL) in California, told Live Science, “even if we are not here some years later.” The new message contains information in binary and describes basic math, physics and biology.
The proposed idea coincides with the 50th anniversary of the Arecibo message which 50 years later does not appear to have ever been intercepted by another world (as far as anyone knows.)
