alien adj.

Subtly, undefinably it was of our world and of one not ours… It had eyes—eyes that were now only shadows darkening within its luminosity like veils falling, and falling, opening windows into the unknowable; deepening into softly glowing blue pools, blue as the Moon Pool itself; then flashing out, and this only when the—face—bore its most human resemblance, into twin stars large almost as the crown of little moons; and with that same baffling suggestion of peep-holes into a world untrodden, alien, perilous to man!

I was later to witness the results of the discovery of an alien incubator.

Adam, the Baby, and the Man from Mars have always been invoked in the history of thought as the only three unprejudiced observers of the human scene—Adam, fresh from the hand of his Maker, the Baby new to earth and sky, and the Man from Mars on his first visit to an alien planet.

Here was the display, indeed, of alien science and power!

I knew that it was intelligent, a sentient being. But it was not human, not a thing of flesh and blood at all. It was a machine! Or, rather, it was in a machine, for I felt far more of it than I saw—a will, a cold and alien intellect, a being, malefic, inhuman, inscrutable. It was a thing that belonged, not in the present earth, but in the tomb of the unthinkable past, or beyond the wastes of interstellar space, amid the inconceivably [sic] horrors of unknown spheres.

I led him into my study, shut the door, and sat down by my desk. He remained standing, a striking and powerful figure with his mighty, muscular limbs, his strong and prominent features, and his eyes of penetrating brilliance. Then there was the difference I mentioned, the air of alien power and the strange, malign spirit that lurked in the green-black eyes, setting him apart from ordinary men. ‘Is Pandorina the child of earthly parents?’ he asked harshly, his sharp eyes boring into mine. ‘Why, what makes you ask that?’ I countered, caught unexpectedly, but unwilling to admit anything. ‘You have told her that she is not your child. In pallor of skin, color of hair, and luster of eye, she resembles me. But I am not a terrestrial man. I came to earth in a meteor. I am the son of the science of another world, and I know that two other similar meteors fell on the same evening. I was brought up by a farmer named Mason. He lived in the village of Folsom, over toward Camden. He did not, as you have done, lie to his foster-child about his origin. These are the reasons for my question; these, and the fact that Pandorina and I feel an irresistible attraction.’

This girl, this unknown, unimaginably far-distant girl, perhaps star-born, certainly very alien—had died as all her race must be doomed to die, until the last flicker of that stupendous civilization was stamped out.

He could not guess where he was, in what land or time, in the presence of what alien race. The men were all little and dark and hairy, and somehow crooked, like gnomes. He had never heard a tongue like the gutturals they mouthed.

According to these scraps of information, the basis of the fear was a horrible elder race of half polypous, utterly alien entities which had come through space from immeasurably distant universes and had dominated the earth and three other solar planets about six hundred million years ago.

The killer attacked Jarvey, and then discovered his flesh was alien—uneatable.

They had stumbled upon a long-abandoned alien spaceport.

How plausible is it going to be that we will ever develop handy translating devices that will let us communicate with the inhabitants of alien worlds?
