"The Omega Directive" is the 89th episode of the American science fiction television series Star Trek: Voyager airing on the UPN network.

In this episode, Captain Janeway must undergo a top secret mission to destroy a molecule called an "Omega Particle" that the Federation has deemed too dangerous to be allowed to exist.

She orders the ship's computer to override the lockout and transfer all sensor data to her ready room, but leaves without explaining to her bemused crew what happened.

As Janeway explains, Omega is unstable and even the explosion of one particle out in space can nullify subspace for many light years around it, rendering faster-than-light travel impossible within that area.
