Girlsway Squirting and Scissoring Transmission

In November 1974, astronomer Carl Sagan was asked to devise a message to beam into space via radio waves.

The message was aimed at a cluster of stars known as M13.

The message consisted of 1,679 binary digits transmitted at a frequency of 2,380 MHz.

The ones and zeros were transmitted by frequency shifting at a rate of 10 bits per second.

The total broadcast lasted less than three minutes and in total made up a single bitmap image.
