Arecibo Telescope 1974 Transmitted Message

A sequence intended for extraterrestrial intelligences transmitted in 1974 from the Arecibo radio telescope

In 1974 the bitmap image below was sent as a radio signal from the Arecibo radio telescope. At the left-hand end is a version of the pattern of digits from page 117--but distorted so it has no obvious nested structure. There follow atomic numbers for various elements, and bitvectors for components of DNA. Next are idealized pictures of a DNA molecule, a human, and the telescope.
