And by alien I mean any kind of life, it doesn't have to be sentient.

Personally, I think Europa or Mars might have microbes somewhere.

    I think there's a good chance of microbes on on Europa and maybe in some martian aquifer. Other than that I doubt it unless there's some sort of life form that can live in gas giants.
