Answer:
complex
Explanation:
This is a compound sentence because it contains an independent clause and a dependent clause. An independent clause is able to stand on its own and would make sense as a separate sentence. A dependent clause is awkward if left alone and, as such, needs to be included as part of a sentence.
The independent clase in this example is:
<em>humans were interested in astronomy</em>
The dependent clause is:
<em>even before telescopes were invented</em>
