Armandroff “ he year 2009 was the International Year of Astronomy, biologically or geologically active, fi nding variations in the commemorating two major astronomical achievements concentration of this organic molecule over both time and that took place 400 years ago: Galileo Galilei fi rst turned location. Mumma and his team continue to apply the Keck his simple refracting telescope toward the heavens, and telescopes, particularly our world leading adaptive optics in that same year Johannes Kepler published his book, system and NIRSPEC, a near-infrared echelle spectrograph, Astronomia Nova, describing the fi rst two laws of planetary to more precisely map these methane emissions and guide motion. further research to determine their source. How inspiring to consider what we have learned about the Another highlight of the year occurred in June 2009 when Universe since 1609 when the moons of Jupiter and the laws the Low Resolution Imaging Spectrograph (LRIS), one of physics came into focus. And how humbling to realize of Keck’s fi rst instruments and still our most popular and how many fundamental questions about the cosmos remain productive one, completed a major upgrade to its capabilities. to be answered through the science of astronomy. LRIS is a double spectrograph that obtains data in the red and blue regions of the electromagnetic spectrum simultaneously. It is the W.M. Keck Observatory’s role to answer these The entire red-side detector, electronics, and software were questions and over the past year we celebrated major replaced with state-of-the-art technology. milestones in both astronomical exploration and technology initiatives. It is my privilege to serve as the Director of the The red region upgrade has made LRIS the most sensitive Keck Observatory and to introduce the chronicling of these optical spectrograph in the world. With greater sensitivity achievements in the pages that follow. and lower noise, the instrument now gives Keck astronomers the capability to work on scientifi c problems that were One of the highlights of 2009 took place in January when a previously impossible and surpass observations that we could team of astronomers led by NASA’s Mike Mumma reported undertake before.

In tthisis AnnuAnnualual RepReport you will meet some of the highly trained and dedicadedicated staff members responsible for maintaining and operating the Keck telescopes as well as deploying these technological innovations. Alongside these and other Keck professionals you will also be introduced to leaders from our astronomy community who are contributing by developing new instrumentation or participating in Observatory governance. And you will learn how in the International Year of Astronomy we continued the trend of increasing both the new science enabled is dramatic and the results published quality and quantity of our education and outreach activities over the past fi scal year by Keck’s astronomers are also and growing the number of our philanthropic supporters. quantifi ed in the Report. We are encouraged by the signifi cant interest in and support of our work by the public. In its short history, the twin ten-meter Keck telescopes have pushed Galileo’s fi rst concepts of astronomy to the Modern astronomy is a highly competitive and constantly extreme and brought the beauty, complexities and mysteries changing fi eld, and Keck Observatory continues to be of the cosmos within reach. As an organization we are honed as a powerful discovery machine with additions to proud of what we have accomplished not only in cutting- our telescope instrumentation and enhancements to our edge discoveries but also in training and inspiring the next adaptive optics systems. These technological enhancements generation of explorers. I thank our professional staff, our are complex and require signifi cant resources to design governing board and advisors, our philanthropic supporters, and build. As a private-public partnership, we rely on and our volunteers for all their contributions and for their “ grants from federal agencies and gifts from individuals and steadfast commitment to our continued leadership in this foundations to fund these pathfi nding developments. The amazing scientifi c enterprise. W.M.

Observing time on the Keck telescopes is highly prized and is divided each year among its partner institutions: the California Institute of Technology, the University of California and NASA, as well as the University of Hawai’i. The broader astronomical community has access to the telescopes through partnerships with the National Science Foundation and NASA. Recognized as the most scientifi cally productive observatory in history, Keck Observatory has contributed to all areas of astronomy and astrophysics. Keck’s legacy of exploration includes the discovery of exoplanets; the study of how planets, stars and galaxies form; the nature of black holes; and the chemical composition and evolution of the Universe. Beyond offering the largest light collection mirrors on the planet, the Keck telescopes host a complete suite of nine state-of-the-art observing instruments to collect and analyze astronomical data with unprecedented power and precision. Keck is a world leader in the fi eld of adaptive optics, a breakthrough technology that removes the distortions caused by the turbulence in the Earth’s atmosphere and provides image clarity of cosmic targets that rivals those of the Hubble Space Telescope. Made possible by grants from the W. M. Keck Foundation, the Observatory today is a private 501(c)3 non-profi t organization and depends upon competitive grants and philanthropy to sustain its frontier research capabilities. W.M.
