1. Lens Inquiry A CfAO/ISEE Designed Laboratory Hartnell Community College September 2009

2. State-of-the-Art Telescopes

3. Famous Telescopes: The Hubble Space Telescope Reflecting telescope (Mirrors) with 2.4m Primary

4. Keck: 10m Reflecting Telescopes Each of the primary mirrors is composed of 36 hexagonal segments that work together as a single piece of reflective glass

5. Why build newer, bigger, and better (?) telescopes?

7. M16: Pillars of Creation Credit: J. Hester, P. Scowen (ASU), HST, NASA Explanation: This image, taken with the Hubble Space Telescope in 1995, shows evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust.

8. A Sharper View of a Tilted Planet Credit: Lawrence Sromovsky, (Univ. Wisconsin-Madison), Keck Observatory Explanation: These sharp views of tilted gas giant Uranus show dramatic details of the planet's atmosphere and ring system.

9. Red Saturn Credit: G. S. Orton & P. A. Yanamandra-Fisher (JPL), Keck Observatory, NASA Explanation: This strange, false-color image of otherwise familiar planet Saturn shows temperature changes based on thermal infrared emission in the gas giant's atmosphere and rings.

10. The Hubble Ultra Deep Field Credit: S. Beckwith & the HUDF Working Group (STScI), HST, ESA, NASA Explanation: The Hubble Ultra Deep Field is the deepest image of the universe ever taken in visible light, showing a sampling of the oldest galaxies ever seen, galaxies that formed just after the dark ages, 13 billion years ago, when the universe was only 5 percent of its present age.

11. Neptune through Adaptive Optics Credit: AO Staff, Keck, LLNL Explanation: From the Earth's surface, Neptune usually appears as a fuzzy blotch. This image of Neptune in three infrared colors demonstrates the clarity of the new technique – Adaptive Optics - as compared to an image of Neptune from Keck II without AO.
