Are there microorganisms that live in space?

I was wondering if there has been any solid evidence that any form of microorganism has ever been found in space, or any small life form for that matter.

No. It would be HUGE news. 

Some microorganisms are capable of surviving in space for a while, and so there's actually a huge effort put into sanitizing our equipment before we land it elsewhere - conceivably, a microbe of some sort could survive on Mars if it found a pocket of just the right conditions, and we'd never really be able to tell whether we put it there. 

But life that didn't originate on Earth hasn't been discovered in any way.
