Someday, humanity might receive a message from space that will answer one of the greatest existential questions: is anybody out there? Regardless of the content, a message from an extraterrestrial civilization will be the single greatest event in human history. How would such an event happen, and how would it play out? What will be the repercussions of billions of people suddenly learning that we are NOT alone in the Universe? This question has inspired countless works of science fiction and scientific studies that have attempted to predict (and even quantify) our collective reaction.
This was the purpose behind A Sign in Space, a revolutionary art project designed to simulate a First Contact scenario. This project was the brainchild of Daniela de Paulis, a contemporary artist, and licensed radio operator currently serving as the Artist in Residence at the SETI Institute and the Green Bank Observatory. Together with a team of international experts, including SETI researchers, space scientists, and artists, de Paulis created this campaign to engage the global SETI community and the general public about the possibility of First Contact.
On November 16th, 1974, a coded radio message was broadcast from the Arecibo Observatory in Puerto Rico. The message contained information on mathematics, humanity, the Solar System, DNA, and the Observatory itself. The destination for this message was Messier 13 (NGC 6205 or “The Great Hercules Cluster”), a globular star cluster located about 25,000 light-years from Earth in the constellation of Hercules.
This past summer, the Arecibo Observatory suffered major damage when an auxiliary cable that supports the platform above the telescope broke and struck the reflector dish. Immediately thereafter, technicians with the observatory and the University of Central Florida (UCF) began working to stabilize the structure and assess the damage. Unfortunately, about two weeks ago (on Nov. 6th), a second cable broke causing even more damage.
Following a thorough review, the U.S. National Science Foundation (NSF) announced that the observatory cannot be stabilized without risking the lives of construction workers and staff at the facility. As such, after 57 years of faithful service and countless contributions to multiple fields of astronomy, the NSF has decided to commence plans for decommissioning the Arecibo Observatory.
The Arecibo Observatory is an iconic institution. Located in Puerto Rico, this National Science Foundation (NSF) observatory was the largest radio telescope in the world between 1963 and 2016. While that honor now goes to the Five hundred meter Aperture Spherical Telescope (FAST) in China, Arecibo will forever be recognized for its contributions to everything from radio astronomy to the Search for Extraterrestrial Intelligence (SETI).
Unfortunately, the Arecibo Observatory suffered serious damage when on Monday, Aug. 10th, an auxiliary cable that supports the platform suspended above the telescope reflector dish broke. The cable struck the Gregorian Dome (which sits on the underside of the platform) before landing on the reflector dish, which created a gash over 30 meters (100 feet) in length and forced the observatory to temporarily shut down operations.
