Velvet Goldmine: Rockers from Outer Space?

One of the most puzzling aspects of the film, Velvet Goldmine, is the spaceship image.  The first time we see this spaceship, the film is opening with Oscar Wilde’s supposed birth.  It seems that the spaceship dropped him on a door step.  This spaceship appears again in a scene with Arthur at a Brian Slade concert.  There are several references to drugs during this scene, so the appearance here may have been a hallucination.  None the less, the spaceship does not go unnoticed.   Although the spaceship appears in completely different contexts, there seems to be an underlying theme.  The spaceship may be a representation of how the characters, such as Oscar Wilde, Arthur, Brian, etc., feel like outsiders in society.  The concept of an alien space craft being present in confusing scenes, such as the discovery of baby Oscar, or Arthur under the influence at a concert discovering his sexuality seems to signify its representation of the “outsider” persona the characters possess.  This alien spaceship further displays the characters alienation from the norms of society at the time, whether it be through their taste in music, fashion, or most noticeably, their sexuality.  I am interested to see what others think about the appearance of the spaceship and what it means in the context of the film.
