The 13-page epistle, referred to as the “Beacon in the Galaxy,” is meant to be a basic introduction to mathematics, chemistry and biology that draws heavily on the design of the Arecibo message and other past attempts at contacting extraterrestrials. In early March an international team of researchers led by Jonathan Jiang of NASA’s Jet Propulsion Laboratory posted a paper on the preprint server that detailed a new design for a message intended for extraterrestrial recipients. The odds that at least one of these billions of planets has produced intelligent life seem favorable enough to spend some time figuring out how to say “hello.” Advances in remote sensing technologies have revealed that the vast majority of stars in our galaxy host planets and that many of these exoplanets appear capable of hosting liquid water on their surface-a prerequisite for life as we know it. ![]() Upon discovering the existence of intelligent life beyond Earth, the first question we are most likely to ask is “How can we communicate?” As we approach the 50th anniversary of the 1974 Arecibo message-humanity’s first attempt to send out a missive capable of being understood by extraterrestrial intelligence-the question feels more urgent than ever. ![]()
