Hubble image of galaxies in Sculptor implies 100 billion galaxies in the Universe.

Look back at the image taken by Hubble. Look at it closely. The Universe is so vast it may be impossible for us to grasp its size and scale; yet by studying it, by embracing it, we see that our being a part of it is special.

If there is one most amazing thing that astronomy, that science, has shown us, I believe it is that.
