Hubba Hubble
The Hubble telescope has been up there for fourteen years now-- sadly (infuriatingly) its days may be numbered. It's what it contributes to science and our understanding of the universe, its origins, etc. that makes the Hubble so important of course. But it's also made an aesthetic contribution. I was really amazed by the true beauty of the pictures displayed in this wired.com article, commemorating the telescope's anniversary. They're incredibly eerie, yet breathtaking.
