Ways to celebrate

World Contact Day began with a very specific, very earnest experiment: getting a large group of strangers to think the exact same sentence at the exact same moment, in the hope that someone in space was listening.

The original 1953 telepathy experiment

On March 15, 1953, the International Flying Saucer Bureau, a civilian UFO research club founded by Albert K. Bender, asked its members worldwide to focus on a single message at a set time, reasoning that if telepathy and extraterrestrial life were both real, enough people concentrating on identical words might broadcast it into space. The message opened with the now-famous line "Calling occupants of interplanetary craft!" and asked any listening visitors to "give us some sign that you have received our message."

From UFO club to pop hit

That exact 1953 wording resurfaced more than two decades later as the lyrics to "Calling Occupants of Interplanetary Craft," a 1976 song by the Canadian band Klaatu that The Carpenters covered in 1977, turning it into a top-10 hit in the UK and Canada and a number one in Ireland.

Ways to mark the day now

  • Read the original 1953 message aloud at the same moment as other participants, the way IFSB members originally intended.
  • Explore the real Search for Extraterrestrial Intelligence at SETI.
  • Read about the science of habitability at NASA's astrobiology program.
  • Listen to the Klaatu original or The Carpenters' cover version back to back.
