Signs of humanity have traveled through space ever since the very first radio signals left the Earth’s atmosphere. We even made concerted efforts to broadcast evidence of our existence through projects like the historic Voyager spacecraft recordings—but an official intergalactic tourism campaign advertising alien vacations to the “Horse Capital of the Word?” That’s a first.

The Lexington Convention and Visitors Bureau (VisitLEX) recently turned to University of Kentucky professor and longtime SETI advocate, Robert Lodder, to assemble experts from various disciplines including linguistics, philosophy, and design to attract a unique target audience: (potential) extraterrestrial lifeforms. More specifically, any extraterrestrial life possibly residing within the TRAPPIST-1 system.
Located approximately 40 light-years away in the Leo constellation, TRAPPIST-1 is by far the most studied planetary system outside of our own. There, seven rocky planets orbit a small red dwarf star, three of which reside within its “Goldilocks zone”—the region astrobiologists believe could be conducive to supporting life.
“Many previous transmissions have employed the language of mathematics for communication, and our team did, too,” Lodder tells PopSci. “But we decided that extraterrestrials might be more interested in things unique to Planet Earth than Universal Truths like mathematics, so if we seek to attract visitors, it would be best to send something interesting and uniquely Earth.”
Collaborators ultimately decided on a package including black-and-white photographs of rolling Kentucky bluegrass hills, an audio recording of local blues legend, Tee Dee Young, and an original bitmap illustration—a type of image in which programmers use basic coding to…
