There's a pretty clear theme to the site. Space stuff. The background is ultra deep field astrophotography. I wrote a poem a while ago to explain my love of those photos.
Each warm speck in the vast night is a streetlamp, gently glowing in the swaddling autumn dark A porch light whose inviting halo beckons me with the moths, saying "someone lives here; trick-or-treaters welcome" A living room window where saturday evenings unfold among loving families Bright spots against the black ink of photos in a book by Carl Sagan
When I look at these photos, I can rest easy knowing that what happens here does not decide the fate of the universe. When we are gone, the universe will try again, and again, and again, and again...
