Radio Signals We've Sent


Ever since the late 19th century we have been sending radio signals ... to ourselves but inadvertently also to anybody possibly listening out there. The graphic below shows where these signals are at the moment, and how many stars and exoplanets they have passed since.
Note: this is a preliminary release of this webpage. Still working on it. Any suggestions are welcomed by email.
