I really admire your skill in Astro photography. How on earth (maybe how in the universe is more appropriate ;-) did you manage to take that nice shot?
I think you'll have to post a tutorial on how to take stunning pictures like that :-)
Now one might argue, that there are stars in the background and we are "not allone in the universe" but anyone with a slight understanding of Astronomy knows that the vast distances between stars are inconceivable for the human mind. So I think "alone" is more than justified!
