Explanation:
What are these Earthlings trying to tell us?
The featured message was broadcast from
Earth towards the
globular star cluster
M13 in 1974.
During the dedication of the
Arecibo Observatory - still one of
the largest single radio telescopes in the world - a string of 1's and 0's
representing the diagram was sent.
This attempt at extraterrestrial communication was mostly ceremonial -
humanity regularly broadcasts radio and television signals
out into space accidentally.
Even were this message received, M13 is so far away we would
have to wait almost 50,000 years to hear an answer.
The featured message gives a few simple facts about humanity and its
knowledge:
from left to right are numbers from one to ten, atoms including
hydrogen and
carbon,
some interesting molecules,
DNA, a human with description, basics of our
Solar System, and basics of the sending telescope.
Several searches for extraterrestrial intelligence are currently underway, including
one where you can use your own home computer.

ET life?
