Humans have always been fascinated with space. We frequently question whether we are alone in the universe. If not, what does intelligent life look like? And how would aliens communicate?
The possibility of extraterrestrial life is grounded in scientific evidence. But the distances involved in travel between the stars are vast. If we do contact aliens, it would likely be via long distance communication, with our nearest neighbouring star being 4.4 light years away. Even being optimistic, it would likely take more than ten years for any round-trip communication.
