Sundown

The sun drops behind the cloud layer, hastening the night. In just a few minutes the stars become visible.

Observation [45]

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).

Pu`u Poliʻah [47]

Pu`u Poliʻahu

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.

Pu`u Poliʻahu is prominent cinder cone at the top of Mauna Kea. If you look closely, you’ll see a shrine that appears to be a pair of vertical poles.

Poliʻahu is the snow goddess deity. According to legend, she inhabits the summit of Mauna Kea and rules over the northern side of the island, whereas Pele, the volcano goddess, rules Kīlauea and Mauna Loa on the southern side of the island.

In winter, Poliʻahu is evident, as it can actually snow at the top of Mauna Kea. It must be quite a thing to go from sun drenched beaches to snow on the same island.

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.

Mauna Kea – Southern Slope [52]

Mauna Kea - Southern Slope

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.

Mauna Kea is a dormant volcano with its summit is at 13,796 ft above sea level

This picture was taken above the Onizuka Center for International Astronomy Visitor Information Station. You can see it at the bottom right hand corner of this picture. The station is at 9,300 feet above sea level and our tour group stopped there briefly to acclimate to the altitude and look through some solar telescopes. We stopped again at approximately 10,300 feet to take some pictures. Here you can see a number of cinder cones. And yes, those are clouds. Some of the other pictures show even more dramatic views of the cloud layer as seen from above.

Maui at NightFall [53]

Maui at Nigtfall

It took us several days to realize we could see Maui from the Big Island. It was often covered in clouds, as we were looking at its windward side. This evening, the sky was clear enough to see a nice silhouette of the neighboring island.
