Scientific paper

The technical status is reported for the Keck 1 and Keck 2 observatories. The Active Control System cabling to the node boxes, and the boxes themselves, have been installed on the telescope of Keck 2 and are ready for segment installation. Progress continued during this period on the development of adaptive optic and interferometric capabilities. The image quality of the 92 scheduled nights over the last quarter is unsurpassed for any large telescope in its first few years of full operation, a tribute to the care that went into the design for maintaining good thermal conditions inside the dome. However, the images could be much better and will be the focus of future studies. The highlight for the quarter is the discovery of the most distant galaxy ever detected. At 14 billion light years from earth, the discovery pushes back the earliest known time when galaxies were formed to only one billion years after the current estimate for the 'Big Bang' birth of this universe.
