Yes, it is! It's used frequently and means "known or visible for everyone to see" or "no longer a secret." Ex: Now that my secret is out in the open, I can finally be honest with you about everything. Ex: I think we should get what's bothering us out in the open. Ex: The governor's political plans are now out in the open.
