Regardless of the evolutionary process involved in producing an extra-terrestrial intelligence, communication between entities would most likely take place somewhere within the electromagnetic spectrum. There are many ideas on what form this communication may take. As an example, Leon T. Darcy discussed his theory in the Autumn 1999 issue of SearchLites . We should now be considering technologies just beyond the cutting edge. They may represent the future of interstellar communications.
New satellites are presently under development.
