   Explanation: How far can you see? The [4]Andromeda Galaxy at 2.5
   million light years away is the most distant object easily seen with
   your unaided [5]eye. Most other apparent denizens of the night sky --
   [6]stars, clusters, and nebulae -- typically range from a few hundred
   to a few thousand [7]light-years away and lie well within our own
   [8]Milky Way Galaxy. Given its distance, light from [9]Andromeda is
   likely also the [10]oldest light that you can see. Also known as M31,
   the Andromeda Galaxy dominates the center of the featured [11]zoomed
   image, taken from the [12]dunes of Bahía Creek, [13]Patagonia, in
   southern [14]Argentina. The image is a combination of 45 background
   images with one foreground image -- all taken with the same camera and
   from the same location within 90 minutes. [15]M110, a [16]satellite
   galaxy of Andromenda is visible just below and to the left of M31's
   core. As [17]cool as it may be to see this neighboring galaxy to our
   Milky Way with your own eyes, [18]long duration camera exposures can
   pick up many faint and breathtaking details. [19]Recent data indicates
   that [20]our Milky Way Galaxy will [21]collide and combine with the
   similarly-sized Andromeda galaxy in a few billion years.
