Getting Published

I am working on a science-fiction novel which I would like to get professionally published. How do I go about contacting a publisher?

Daniel, I have not done it myself but I recommend going on google and typing in, "How to get published" or "How to get published in America."

I live in Canada, and typing one of the above takes me to The Writer's Union of Canada website which teaches me how to get published in Canada. So, do something like that.
