I remember a scene from a movie or TV series that I saw in the 80's. It was set on what I think was an abandoned spaceship. An astronaut (main character?) finds a dead crew-member in full space-suit, covered by dust. He (she?) carefully whipes off the dust on visor and reveals the skull of an alien with sharp teeth.
I know this is very thin, but hopefully somebody know what I'm talking about. I've looked through the epguides for the Twilight Zone (1985 version) since i remember following that series, but it doesn't fit any episode. It's very possible the movie was made in the 70's and is more horror than SF.
While looking I came across Old movie with abandoned spaceship on this site, but it's not The Starlost or any old "tacky" series like that.
