These photos are exquisite. I find it difficult to believe that if we could vertically sum across people's preferences, we would not come up with a sum that would be more than enough to renovate the Hubble and send up another space telescope as well. Of course identifying and collecting the sums would be no easy task. And it's easy for me to say all this since the contributions of Canadian taxpayers to the Hubble are likely to be miniscule.
I think my favourite of the images is the "hour glass nebula".
