How to Tweet to Aliens Tonight
This article was updated 7/2 at 3:30 p.m. EDT.
Don't forget to contact aliens this evening.
All Twitter messages composed between 8 p.m. EDT Friday (June 29) and 3 a.m. EDT Saturday (June 30) tagged with the hashtag #ChasingUFOs will be collectively beamed up to space Aug. 15, toward a region of the sky that may contain a habitable, life-bearing planet.
The cosmic tweet is a belated reply to the Wow! signal, a mysterious radio transmission that was detected at the Big Ear radio observatory in Ohio in 1977 coming from the direction of the constellation Sagittarius. At its peak, the 72-second transmission was 30 times more powerful than ambient radiation from deep space, prompting the volunteer astronomer Jerry Ehman to scrawl "Wow!" next to the data on a computer printout, giving the signal its name.
No one knows whether the seemingly unnatural blip of data really was beamed toward Earth by aliens, and despite great effort, scientists have never managed to detect a repeat transmission from the same spot in the sky. Thirty-five years on, the Wow! signal remains an anomaly.
Now, the Sagittarius aliens — if they do, in fact, exist — are finally getting humanity's response. The National Geographic Channel has organized the cosmic social media event to coincide with the premiere of its new series, "Chasing UFOs." [Roswell, Other Famous UFO Claims Get a Fresh Look]
All #ChasingUFOs tweets, as well as several 72-second video messages being created by celebrities, writers, artists, filmmakers, musicians and scientists, will be rolled into a single message for space, according to the National Geographic Channel. The message will then be encrypted with the help of astronomers at Arecibo Observatory in Puerto Rico, and beamed skyward.
"More than likely, we will be using binary phase codes," or sequences of 1s and 0s, said Kristin Montalbano, a spokeswoman for the National Geographic Channel. "The [alien] scientists, on the other end, would theoretically be challenged to find a way to decrypt the transmission and understand our language," Montalbano told Life's Little Mysteries.
Hopefully, Twitter slang won't throw them off.
So, if you have something you'd like to say to E.T., let it rip — but make sure you keep it to 140 characters or less.
