Keck I and II observatories on Mauna Kea, Hawaii
Keck observatories. Domes of the Keck I (at left) and Keck II optical telescopes at sunrise at the Mauna Kea observatory in Hawaii, USA. Keck I is seen partially open. Each telescope has a 10 metre diameter mirror to focus light. The mirrors are made up of 36 hexagonal units with a 1.8m diameter which are mounted on computer-controlled motors that make tiny adjustments to keep astronomical objects in precise focus. The two telescopes can be used to observe the same object and can have their signals combined by interferometry to obtain a more accurate image. In 1997 the Keck telescopes are the largest optical telescopes in the world

EDITORS COMMENTS
This print showcases the iconic Keck I and II observatories on Mauna Kea, Hawaii. As the sun begins to rise, the domes of these remarkable optical telescopes stand tall against the picturesque backdrop of the Mauna Kea observatory. The partially open dome of Keck I is visible, revealing its impressive 10-meter diameter mirror that plays a crucial role in focusing light from celestial objects. What makes these telescopes truly extraordinary are their mirrors composed of 36 hexagonal units with a diameter of 1.8 meters each. These intricate mirrors are mounted on computer-controlled motors that make minute adjustments to ensure precise focus on astronomical phenomena. Furthermore, both telescopes can observe the same object simultaneously and combine their signals through interferometry techniques, resulting in incredibly accurate images. It is worth noting that during 1997 when this photograph was taken, the Keck telescopes held the distinction of being the largest optical telescopes worldwide. Their presence at Mauna Kea has made it one of astronomy's most significant sites for exploration and discovery. This stunning image from Science Photo Library not only captures the grandeur and technological marvels represented by these observatories but also serves as a testament to humanity's relentless pursuit of knowledge about our vast universe.
