which episode?

[henksocrates]

hello there!
I am looking for a episode of voyager where the crew is trapped in time/space loop: they see another spaceship, but even at warpspeed they always seem to end up where they began: looking at the other spaceship.
they figure out they are looking at there own mirror image. they eventually shoot a hole in the mirror and escape.

does anyone know the name of this episode?

thanks! (henksocrates@live.nl)

You're thinking of "Parallax," the first episode after "Caretaker."
