Ground based astronomy has an exciting future ahead
While I love the Hubble space telescope, we are rapidly approaching the point where astronomy in the near IR and visible wavelengths is best done from the ground. We already can outperform the Hubble in the near IR wavelengths.
I think Galileo would be astounded at the evolution of his invention. I feel genuinely sorry that he never knew the full impact of his work... (Yes I know, many others were also responsible for that first telescope)
