The Process
How it works
From your words to the edge of the known universe — in four steps.
Write your message
Up to 100 words. A love letter, a question, a declaration. Whatever you most want the universe to hear.
Choose your star
Alpha Centauri, Vega, Polaris, Betelgeuse — or cast your words into infinite deep space. Each destination has its own story.
Join a transmission
Your message encodes to binary, joins a scheduled batch event, and broadcasts at 1420 MHz — the universal frequency of hydrogen.
Receive your certificate
A verified Transmission Certificate with your signal ID. Track your message as it moves further from Earth, every second, forever.
The Encoding
Words become signals
Every character in your message is converted to binary and broadcast at 1420.405 MHz — the universal hydrogen line, the frequency the cosmos already knows.
Destinations
Choose your star
Every star has a story. Every signal has a destination. Where will yours go?
No destination. Infinite void between galaxies. Your message travels forever.
Our nearest galactic neighbour. Two trillion stars await your signal.
The closest star system to Earth. Your message arrives in 4 years and 4 months.
Seven Earth-sized planets. Three in the habitable zone. The best odds we know of.
A dying red supergiant. One of the largest, most ancient stars visible from Earth.
The Seven Sisters. One of the most recognizable star clusters in the night sky.
The North Star. For millennia it guided every traveler on Earth.
