Observation

The last rays of the sun bathe the observatories at the summit of Mauna Kea in golden light while the clouds below us tumble by.

The Canada-France-Hawaii Observatory (left) has opened its doors in anticipation of a night of astronomical observations. Observatories open their dome doors well before they begin observations in order to equalize the temperature inside the dome with the outside temperature (about 40° F). This stabilizes the air around the telescope, preventing convection currents that disturb observation

Sunset at Mauna Kea [46]

Sunset at Mauna Kea

One of the best adventures we had on the Big Island of Hawaii was to book a Mauna Kea sunset tour. The tour took us in four wheel drive vans to the summit to watch the sun set and learn about the observatories, geology, ecology and spirituality of Mauna Kea.

The sun sets beyond the clouds. In the foreground (left to right, you can see Keck II and the NASA Infrared Telescope Facility (IRTF).

Keck Observatories[51]

One of the best adventures we had on the Big Island of Hawaii was to book a Mauna Kea sunset tour. The tour took us in four wheel drive vans to the summit to watch the sun set and learn about the observatories, geology, and ecology of Mauna Kea.

We stopped before the sunset at the summit and our tour guides described the various observatories that have been built there. The summit of Mauna Kea is an ideal location for telescopes because it is above the cloud layer, low in atmospheric and light pollution, and the air is dry and thin – all qualities that improve the quality of astronomical.
observations.

This picture shows the twin Keck Observatories. The telescopes are unique because they each use multiple, separate hexagonal mirrors that operate as if they were a single contiguous mirror. Furthermore, the two observatories can be used to simultaneously image the same celestial object to produce a higher resolution image than can be achieved with a single telescope.
