On our website, the image above is only about 730x230 which, trust me, doesn't do it justice. It's actually the largest photo in existence, captured by NASA's Hubble Space Telescope, featuring the Andromeda Galaxy, the closest spiral galaxy to our Milky Way, though it's actually 2.5 million light-years away.
Few of us are likely to ever see the entire photo in its complete resolution. It contains 1.5 billion pixels and would require 600 HD televisions to properly display. The zoom tool makes it much easier and will make you feel very, very small.
Feel free to download the entire image, if you've got a free 4.3 GB on your hard drive. Zoom in and see if you can count all 100 million stars. (Maybe if you've got a few vacation days.)
