I wonder if there's any life up there.. (moon trace)

I took this photo with a 30 minute long exposure. Since the stars and the moon rotate a full 15 degrees every hour and there was a lot of ambient light where I took the photo, I used a 30 minute long exposure to keep the sky as dark as possible and to have a good moon trace of 7 1/2 degrees. I also used f22 and ISO 100.
