  1. The Wondrous Properties and Results of the HST. C. R. O’Dell Department of Physics and Astronomy Vanderbilt University Summer School-2008

  2. Reasons for going into Space • Earth’s Atmosphere Blurs Out our View even when it is perfectly clear. This means that our view of the heavens is like that from a small telescope. • Usually a bigger telescope produces a sharper image. The HST images are 20X better than what is allowed by our Atmosphere. • The atmosphere also limits the energies of the photons that we can see.

  29. James Webb Space Telescope 6.5-meter effective aperture (HST is 2.4-m) Images will be not as sharp as the HST. Primarily will target COLD objects. Now in final design phases. Scheduled launch is in 2012 (similar space- craft have taken 10 years from this point.

  30. JWST-Spacecraft

  31. JWST-Movie goes here.

  32. Reading Material • “The Space Telescope” by Robert W. Smith. Cambridge University Press, 1989(pre-launch) & 1993(post-launch). • “The Orion Nebula” by C. Robert O’Dell, Harvard University Press, 2003 (Chapter 10).

  33. A Summary • The HST represents the results of some 20 years of effort of an important fraction of US and European scientists. • Thus far we have 19 years of return on this investment, with a promise of much more. • Clearly, this has been the most powerful telescope ever built. • There’s plenty of room for a new generation of scientists to do even better.
