The summit of Mauna Kea, credit Ric NoyleThe international astronomical community has converged in Honolulu. The timing—in the midst of the controversy surrounding the construction of TMT on Maunakea—has motivated some who oppose TMT to engage these distinguished guests, hoping they will take a stand. Though well intended and keen to see a lasting, peaceful resolution, these visiting astronomers are not the solution to Hawaii’s longstanding issues. They will leave just a few short days from now, returning to distant countries, yet our challenges will persist. It is our responsibility—those of us who call Hawai‘i home and care deeply about the future of Maunakea—to come together, listen to each other, and find a new path forward.
The cultural, spiritual, historical, scientific, and political perspectives being discussed in our community today are the building blocks of resolution. Maunakea is a critically important site of tremendous tradition and strength for the people of Hawai‘i. One of those strengths is the fact that Maunakea is the foremost site for astronomical observation in the world, providing a significant fraction of the new knowledge of the universe available to all of humanity. The challenge before us, the people of Hawaii, is to come together to create a lasting, inclusive, and beautiful union of all of our strengths. We must find a holistic vision for Maunakea, as the pinnacle of our past and the beacon of hope for our future. The voices opposing TMT have given all of us the opportunity to create the next chapter in Hawaii’s history with Maunakea at its heart. Let us seize this moment and do this together.
More scanning, more memories. Taking these old photos out of the boxes has been fun. So many little treasures on celluloid. Photos of myself as a teenager, photos of the neighborhood I grew up in. There is so much of my life stowed away out of reach, converted to digital they live again…

Regular readers may have noted that I have recently published three articles exploring the subject of the sacred mountain. Each article may have had a different subject, but all overlapped and intertwined. All three articles end with the same paragraph.
A radio telescope of the Very Long Baseline Array stands in the background of an ancient ahu atop Mauna KeaAll were started at the same time, I just kept having different lines of though while exploring the subject. I could not weave the result into a single article. In the end I separated the three posts into a trilogy…
Mauna Kea is sacred to some, who believe that this place is pivotal, the piko of creation. Others believe that the telescopes are sacred, a testament to the finest aspirations of mankind, to learn and explore, to answer the great questions. It is a mistake, made by many in this controversy, to deny either of these views.
Much of the controversy that surrounds our mountain revolves around a few simple questions… Who defines what sacred means? What sacred means to me and what sacred means to you is often very different. Even within a group of adherents to a single faith the answer will often vary greatly. What can you and can you not do on a sacred site? Some believe that a sacred site should not be touched, or even entered. Others build great temples or shines over the site to which thousands or millions of people make a pilgrimage to visit.

Yet the ancient Hawaiians did use this place. They built ahu, they mined for the hard stone prized for making adzes, tools that built the great ocean going waʻa. Is the top five hundred feet of the mountain sacred, or all of it? Are all of the homes and farms that dot the flanks of Mauna Kea a desecration? There is no simple answer here. Anyone who claims otherwise is not being truthful.
The Temple of Mauna Kea differs from other temples because it was not created by man. Akua built it for man, to bring the heavens to man. – Kealoha Pisciotta
“To bring the heavens to man”, is this not what the great telescopes do? Are these great instruments of science an appropriate use for this place? This would not be a question if there were other places where the view of the universe as clear as Mauna Kea. But such places are rare, and none quite so good as this mountain. This one place is unique, particularly suited for studying the heavens. Thus the clash of culture and science has been defined upon this mountain.
Yes, Mauna Kea is sacred. It is sacred for the honor and opportunity it provides us. Yes, Mauna Kea warrants the highest level of cultural sensitivity, but it should be a cultural sensitivity that respects and celebrates exploration of the universe and that is totally consistent with the historical record of Hawaiians and their search for knowledge. – Peter Apo
Over the next few days the Perseid meteor shower will peak. As the most reliable shower each year this is also the most viewed meteor shower. Plentiful shooting stars combined with warm summer evenings makes this shower the easiest and most comfortable to view across much of the northern hemisphere. Quite a difference from the other reliable showers such as the Leonids and Quadrantids, that occur in November and January. Consider a warm summer night under a dark sky full of stars, a picnic blanket, relaxing while shooting stars streak across the sky. What could be better?
A pair of Leonid meteors streak through OrionThe Perseid meteor shower occurs when the Earth passes through a stream of debris along the orbit of Comet Swift-Tuttle. This shower has been consistent throughout recorded history, mentioned in Chinese, Japanese and Korean records as early as the 1st century. Active from July 17th to August 24th, the shower will build slowly for weeks before the peak. A week before or after peak the shower can still be seen with around 20 meteors each hour. The shower is a northern hemisphere event, for southern observers the radiant never rises above the horizon.
You might recall a post from back in May describing a night spent on the summit with Jason Chu. He has been accumulating time lapse material for a significant project, capturing the telescopes of Mauna Kea under the beauty of the night sky.
Jason has published a preview of the work. Nice to see it come to life with a decent soundtrack and good editing…
Previous forecasts showed the hurricane passing well north of the island, following the same track as the last two storms. Then this evening’s forecast came out.
A team of astrophysicists using the W. M. Keck Observatory in Hawaii has successfully measured the farthest galaxy ever recorded and more interestingly, captured its hydrogen emission as seen when the Universe was less than 600 million years old. Additionally, the method in which the galaxy called EGSY8p7 was detected gives important insight into how the very first stars in the Universe lit-up after the Big Bang. The paper will be published shortly in the Astrophysical Journal Letters.
EGSY8p7 is the most distant confirmed galaxy whose spectrum obtained with the W. M. Keck Observatory places it at a redshift of 8.68 at a time when the Universe was less than 600 million years old. Credit: Adi Zitrin, California Institute of TechnologyUsing Keck Observatory’s powerful infrared spectrograph called MOSFIRE, the team dated the galaxy by detecting its Lyman-alpha emission line – a signature of hot hydrogen gas heated by strong ultraviolet emission from newly born stars. Although this is a frequently detected signature in galaxies close to Earth, the detection of Lyman-alpha emission at such a great distance is unexpected as it is easily absorbed by the numerous hydrogen atoms thought to pervade the space between galaxies at the dawn of the Universe. The result gives new insight into cosmic reionization’, the process by which dark clouds of hydrogen were split into their constituent protons and electrons by the first generation of galaxies.
“We frequently see the Lyman-alpha emission line of hydrogen in nearby objects as it is one of most reliable tracers of star-formation,” said California Institute of Technology (Caltech) astronomer, Adi Zitrin, lead author of the discovery paper. “However, as we penetrate deeper into the Universe, and hence back to earlier times, the space between galaxies contains an increasing number of dark clouds of hydrogen which absorb this signal.”
Recent work has found the fraction of galaxies showing this prominent line declines markedly after when the Universe was about a billion years old, which is equivalent to a redshift of about 6. Redshift is a measure of how much the Universe has expanded since the light left a distant source and can only be determined for faint objects with a spectrograph on a powerful large telescope such as the Keck Observatory’s twin 10-meter telescopes, the largest on Earth.
As I scan slides I find little treasures like this one. A foggy morning on the Little Ouse river near Thetford, England, a place I called home for nearly three years. Yes, there is really a river named the Little Ouse!
