If aircraft had nozzles all along their wings people would've noticed them.
What's really going on here is, the plane is flying through high-humidity air. Wings are designed to create lift, and they do so by making air take a longer path across the top of the wing than the bottom, reducing the pressure and pulling the wing up. Reducing the pressure of a gas also cools the gas, and here the air is cooling enough to trigger condensation, generating droplets of water in the form of clouds.
