The word 'aliens' is used in many contexts, conjuring up a range of sentiments including fear, dislike and also fascination. It is used to describe strange beings from Mars, human migrants, and non-native plants and animals - the term is employed by biologists to indicate organisms that have been introduced by people to new territories.
