Telescopes have come a long way since Galileo peered through his first "spy glass" nearly 400 years ago. Today, the Hubble Space Telescope regularly returns spectacular images of features throughout the universe. In the near future, inflatable "Gossamer" antennas will allow us to view the neighborhoods of black holes with 3,000 times better resolution than Hubble. While the future telescopes may be the size of a tennis court, they will be one hundred times lighter than existing technology. These "feather weights" of the future will significantly reduce launch costs and provide the sharpest views yet, helping us explore the farthest reaches of the universe. This lecture will examine how telescope technology has evolved over the centuries and how it will soon produce the most advanced space observatories ever built by humans.
