D3. GALAXY If we look at the night sky with the naked eye we see an array of distinct dots – planets, stars, distant galaxies. If we look at the heavens through a pair of binoculars, we ‘zoom in’: some of the nearer objects appear larger, previously invisible stars appear. The sight that we see is statistically similar to our our first view. We can continue this zooming in with more and more powerful telescopes, each time seeing a smaller portion of the night sky, but in greater detail. This is fractal behaviour.
