Is WMAP and COBE a map of the universe? It look like a globe but with hotspots? I have read that it is a map of our known universe. Is that true?

Are universe expand all the time? This is a question i have been looking an answer to for many months. Maybe you guys here can help me?=) And IF the universe is expanding, how can it do that? And what does it expand in? A greater space?
