So this is the first discovery of an extraterrestrial species right, because that's pretty neat.

  It's not alien origin, it came from earth. Maybe it's post-terrestrial ?

    The prefix extra- just means beyond/outside. It lives outside Earth (Terra) so it's extraterrestrial. Though if you said it's not diverged enough to be a separate species that would be a better objection.

      1. The ISS drags into Earth's atmosphere, anything happening there is earthly. 20,000km further you'd have a point. 2. That's your own interpretation of the word. The actual definition of extraterrestrial life is life that did not originate on earth.

        > The actual definition of extraterrestrial life is life that did not originate on earth. While I would not consider something that evolved on a space station around Earth as extraterrestrial, this seems a bit restrictive. This would rule out any life evolving from Earth material on Mars brought by a rover as extraterrestrial even million years later. Also, if we discovered life came from an asteroid, we might have to consider ourselves as extraterrestrial with such a definition. (though I would not know how to define the word)
