jupiter with some of his moons... europa, io, kallisto and ganymed.
the moons have been discovered by galileo galilei and simon marius.

actually europa is fully covered with organic material. the building blocks of life.
europa is probably full of life. and.. if there is another spot in our solar system,
where life has developed independent from us... chances are good that our
whole galaxy is full of life...

anyways, heres the image:
