 * 1) The Center for High Angular Resolution Astronomy focuses on finding Astronomical optical or infared interferometry to high resolution observations to view properties of stars.
 * 2) UC Berkeley's Charles Townes was the first man to work on Infared interferometry on Mt. Wilson, California; where the CHARA Array is stationed
 * 3) Dual operating wavelengths of 0.15 & 0.6 resolution.
 * 4) Delay Compensator matches paths within 1 micron.
 * 5) CHARA is operated by Georia State University. Most operations are controlled from Atlanta, Georgia. There are 8 Telescopes, 2 Solar Towers, A large beam combining lab, 500,000 gallon water tank, Observatory museum, Engineering shop, and Manager's residence. All on the Peak of Mt. Wilson which has also been used by the Universities of Sydney (Australia), Michigan (U of M), Illinois (U of I), South Carolina (USC), and California: Los Angeles (UCLA).

=__3 Advantages of using the radioactive isotope/radiation/benefits of discovery__=

1. The CHARA array has the ability to see through Dust, Clouds, Gases, etc. to view the stars because of the use of Infared Interometry. 2. The CHARA array has 8 telescopes for optimum view of space. The 2 largest telescopes are eqipped with Infared optical lenses, meaning that they have the ability to see throught anything, however don't get a good look at stars, galaxies, etc. but find the stars and look at them closer when conditions are better. 3.The tracking of stars and galaxies is correct to within a micron. =__Is the radioactive isotope/radiation/discovery still used today? Explain__= Yes, it is imperative for the telescopes to be used with Infared Inferometry to track the stars. =__References__= - "The CHARA Array of Georgia State University" - [] - Google Search- Photos - Wikipedia- The CHARA Array =__Diagram/image (include source and caption)__=
