Mauna a Wakea: Hawai'i’s sacred mountain and the contentious Thirty Meter Telescope

Hawaii's Thirty Metre Telescope (artists tic design)

Plans to build a new telescope on Mauna Kea in Hawai'i have led to months of protests and arrests, including several earlier this month. The ongoing protest pitches astronomers against Hawaiians wanting to protect their sacred site.
Conflict between Indigenous and Western interests are part of a long history of colonisation and exploitation. In the Amazon, indigenous communities are fighting governments that exploit the rain forest for natural resources. In the United States and Canada, First Nations people are battling mining and oil interests.
In Western Australia, Aboriginal people are finding their 30,000 year old rock art sites being deregistered as sacred because they must be “devoted to a religious use” rather than be “a place subject to mythological story, song, or belief”. Many of these sites are in areas of industrial expansion.
If the traditional custodians of the land reject proposals for development, they might face aggressive legal action. “No” is rarely a good enough answer for those exploiting the land, and seeking permission from indigenous people often smacks of tokenism rather than a real attempt to address the wrongs of the past.

The mountain of Wakea

Unfortunately, it is not just economic interests that put pressure on indigenous communities. Scientific interests prove another challenge to indigenous land rights. One such case is the development of the Thirty Meter Telescope (TMT) in Hawai'i.
On Hawai'i’s Big Island stands Mauna Kea, a dormant volcano towering 4,200 meters above sea level. Its high elevation and excellent atmospheric conditions make it an ideal place for astronomers to observe the stars. Mauna Kea is named for the god Wakea, the “sky father” – Mauna a Wakea. It is Hawai'i’s most sacred place.
It is important to note here that only people of Indigenous Polynesian Hawaiian heritage are called “Hawaiian”. Non-Indigenous people born in Hawai'i are called “Kama'aina” meaning “child of the land”, or “people of Hawaii” in general conversation.
Hawaiian reverence for Wakea meant that in ancient traditions only the Ali'i (high chiefs) were allowed to climb to its summit, where their most sacred ancestors are buried. It is here that astronomers plan to build a US$1.5-billion telescope with a primary mirror measuring 30 meters across.

The TMT offers potential scientific discoveries as well as economic benefits for the island. Currently there are 13 telescopes atop Mauna Kea but many Hawaiians are angry about the push to add more telescopes to the mountain, insisting enough is enough.
A resurgence of Hawaiian culture and language has led to the reclamation of sacred sites, including Mauna Kea, as areas of high cultural significance. Hawaiians wanting to preserve their cultural heritage are now clashing with proponents of the TMT. In recent months, protesters have blocked access to the mountain, halting development of the telescope.

An ongoing concern

Should astronomers be allowed to build the TMT on Mauna Kea? This question raises concerns that we, as practising astronomers, see as a reoccurring issue within the scientific community.
It is disheartening and frustrating to witness fellow scientists dismiss the connections indigenous people have to their land. We cannot simply disregard these connections as myths and legends, and comparing TMT protesters to Biblical Creationists is disappointing.
This is not a battle between religion and science. Hawaiians are not anti-science; they are not trying to push their traditional beliefs on others nor are they trying to stifle scientific and economic advancement. They simply oppose construction of yet another telescope on their sacred mountain.
We need to recognise and respect the close connection Hawaiians have to sacred sites like Mauna Kea and not misappropriate Hawaiian astronomical traditions for the benefit of astronomers.
The TMT demonstrates a microcosm of the challenges indigenous people face when their traditions are dismissed by Western interests for intellectual or economic gain.

Moving forward together

We acknowledge that some Hawaiians do in fact support the TMT, while others are calling for the removal of all telescopes. Governor David Ige offered one compromise: the removal of a quarter of the existing telescopes before building of the TMT commences.
We do not have a convenient solution to this issue. So how do we move forward together?
We can look at successful collaborations between scientists and indigenous people on other projects for guidance. The development of the Square Kilometre Array radio telescope in Western Australia was a result of close collaboration and ongoing consultation between astronomers and the traditional owners of the land.
We can take inspiration from the Polynesian Voyaging Society and Hoku'lea – the Hawaiian voyaging canoe. By working closely with artisans, navigators, astronomers, and historians, Hawaiians are reclaiming their ancient knowledge and in turn are sharing this with the world.
These two examples suggest nurturing mutually respectful relationships is the key to overcoming conflict.
This is a highly complex issue. We astronomers need to acknowledge that we do not have an inherent right to develop Mauna Kea. And if a consensus cannot be reached we must be willing to consider a different home for the TMT.

Identifying Seasonal Stars in Kaurna Astronomical Traditions

By Duane W. Hamacher

Early ethnographers and missionaries recorded Aboriginal languages and oral traditions across Australia. Their general lack of astronomical training resulted in misidentifications, transcription errors and omissions in these records. In western Victoria and southeast South Australia many astronomical traditions were recorded but, curiously, some of the brightest stars in the sky were omitted. Scholars claimed these stars did not feature in Aboriginal traditions. This continues to be repeated in the literature, but current research shows that these stars may in fact feature in Aboriginal traditions and could be seasonal calendar markers. This paper uses established techniques to identify seasonal stars in the traditions of the Kaurna Aboriginal people of the Adelaide Plains, South Australia.

Aboriginal languages could reveal scientific clues to Australia’s unique past

By Robin Whitlock (with some edits by Duane Hamacher for accuracy)
The loss of Australian aboriginal languages could obstruct access to unique scientific information regarding Australia’s ancient geological history, according to a story reported this week by BBC News.
Ancient Australian Aboriginal legends passed down over millennia appear to verify recent scientific discoveries regarding Australia’s ancient past, including a previously untapped record of natural history among the stars. Investigation of such a resource could reveal memories of ancient meteor strikes from thousands of years ago according to research at the University of New South Wales (UNSW).

Dr Duane Hamacher of UNSW’s Nura Gili Indigenous Programs Unit has been able to match Aboriginal stories to impact craters dating from 4,700 years ago. One such location, at Henbury in Australia’s Northern Territory, is reflected in local oral traditions that have been passed down across the generations.
Henbury Meteorites Conservation Reserve, located 145 kilometers south west of Alice Springs, is estimated to have hit the earth’s surface 4,700 years ago, it contains 12 craters in total.

Indigenous Australian history is believed to span a period of between 40,000 to 45,000 years with some estimates indicating an Aboriginal presence in Australia some 80,000 years before the arrival of the first Europeans. The number of Aboriginal groups could amount to several hundred, many of which date to well before the colonization of Australia by the British in 1788. The largest of the groups in existence today is the Pitjantjatjara people who live around Uluru (Ayers Rock) and extend into the Anangu/Pitjantjatjara/Yankunytjatjara in South Australia.
It is thought that at the time of the first European settlement in Australia, some 250 distinct languages were spoken among Aboriginal peoples. Given that many of these languages would also have had their own dialects, the number of potential linguistic forms could extend to several hundred, according to authors Michael Walsh and Colin Yallop.

Researchers have fortunately been able to revive one of these ancient languages, previously suppressed by European colonization. The Kaurna language was once spoken by Aboriginal peoples around the present city of Adelaide but it began to disappear from South Australia from the early 1860’s.
According to the stories of the Luritja people, a fire-devil arrived on the Earth seeking vengeance for the breaking of sacred laws. The story was handed down across more than 200 generations before the site of this event was finally identified in 1931.
The Henbury Meteorite Conservation Reserve was previously regarded as a taboo ‘no-go’ area by the Luritja. Scientists have now been able to establish that the ‘fire devil’ was actually an ancient meteorite that blasted several impact craters into the red-colored sand with an atomic level of power.

“Aboriginal oral traditions contain detailed knowledge about the natural world” said Dr Hamacher, who leads a group of nine researchers in Nura Gili's Indigenous Astronomy Group. “By merging scientific data with descriptions in oral tradition we can show that many of the stories are accounts of real-life events. So Aboriginal stories could lead us to places where natural disasters occurred.”
The dozen or so craters created by the meteorite and its fragments have diameters of up to 180 meters across. When scientists first entered the area in 1931, the Aboriginal guide they had brought with them refused to go any further. Luritja elders later told a local resident that the ‘fire devil’ will burn and eat anyone who breaks the sacred law.
Aboriginal peoples hold other stories of ancient natural disasters that have now been shown to be authentic by modern investigation. The Gunditjmara people for instance, tell of a giant wave that swept inland and killed everyone who hadn’t gone up to the mountains.
When Dr Hamacher travelled to Victoria with tsunami expert Professor James Goff, also of UNSW, he found a layer of sediment 1.5 to 2 meters deep at a number of different locations between 500 meters and 1 kilometre inland, suggesting an ancient tsunami had swept over the area hundreds, perhaps thousands, of years ago.
These and other Indigenous stories could be of great benefit to researchers investigating Australia’s history and geology. They also reveal an understanding of the universe among ancient societies, the existence of which wasn’t widely accepted before.
If Aboriginal languages and dialects, that are currently at risk, can be protected and revived, who knows what else they may have to offer?

Fire in the sky: The southern lights in Indigenous oral traditions

Parts of Australia have been privileged to see dazzling lights in the night sky as the Aurora Australis – known as the southern lights – puts on a show this year.
A recent surge in solar activity caused spectacular auroral displays across the world. While common over the polar regions, aurorae are rare over Australia and are typically restricted to far southern regions, such as Tasmania and Victoria.

But recently, aurorae have been visible over the whole southern half of Australia, seen as far north as Uluru and Brisbane.

Different cultures

It’s a phenomenon that has existed since the Earth’s formation and has been witnessed by cultures around the world. These cultures developed their own explanation for the lights in the sky – many of which are strikingly similar.
From a scientific point of view, aurora form when charged particles of solar wind are channelled to the polar regions by Earth’s magnetic field. These particles ionize oxygen and nitrogen molecules in the upper atmosphere, creating light.
Auroral displays can show various colours, from white, to yellow, red, green, and blue. They can appear as a nebulous glowing arcs or curtains waving across the sky.
Aurorae are also reported to make strange sounds on rare occasions. Witnesses describe it as a crackling sound, like rustling grass or radio static.
In the Arctic, the Inuit say the noise is made by spirits playing a game or trying to communicate with the living.
In 1851, Aboriginal people near Hobart said an aurora made noise like “people snapping their fingers”. The cause of this noise is unknown.
Aurorae are significant in Australian Indigenous astronomical traditions. Aboriginal people associate aurorae with fire, death, blood, and omens, sharing many similarities with Native American communities. They are quite different from Inuit traditions of the Aurora Borealis, which are more festive.

Fire in the sky

Aboriginal people commonly saw aurorae as fires in the cosmos. To the Gunditjmara of western Victoria, they’re Puae buae (“ashes”). To the Gunai of eastern Victoria, they’re bushfires in the spirit world and an omen of a coming catastrophe.
The Dieri and Ngarrindjeri of South Australia see aurora as fires created by sky spirits.
As far north as southwestern Queensland, Aboriginal people saw the phenomenon as “feast fires” of the Oola Pikka —- ghostly beings who spoke to Elders through the aurora.
The Maori of Aotearoa/New Zealand saw aurorae (Tahunui-a-rangi) as the campfires of ancestors reflected in the sky. These ancestors sailed southward in their canoes and settled on a land of ice in the far south.
The southern lights let people know they will one day return. This is similar to an Algonquin story from North America.

A warning to follow sacred law

Mungan Ngour, a powerful sky ancestor in Gunai traditions, set rules for male initiation and put his son, Tundun, in charge of the ceremonies. When people leaked secret information about these ceremonies, Mungan cast down a great fire to destroy the Earth. The people saw this as an aurora.
Near Uluru, a group of hunters broke Pitjantjatjara law by killing and cooking a sacred emu. They saw smoke rise to the south, towards the land of Tjura. This was the aurora, viewed as poisonous flames that signalled coming punishment.
The Dieri also believe an aurora is a warning that someone is being punished for breaking traditional laws, which causes great fear. The breaking of traditional laws would result in an armed party coming to kill the lawbreakers when they least expect it.
In this context, fear of an aurora was utilised to control behaviour and social standards.

Blood in the cosmos

The red hue of some aurorae is commonly associated with blood and death.
To Aboriginal communities across New South Wales, Victoria, and South Australia, auroral displays represented blood that was shed by warriors fighting a great battle in the sky, or by spirits of the dead rising to the heavens.
Celestial events that appear red are often linked to blood, including meteors and eclipses.
A total lunar eclipse turns the moon red (sometimes called a blood-moon), which was seen by some communities as the spirit of a dead man rising from his grave.
Rare astronomical events were viewed as bad omens by cultures around the world. Now imagine if two of these events overlap!

In 1859, Aboriginal people in South Australia witnessed an auroral display and a total lunar eclipse. This caused great fear an anxiety, signalling the arrival of dangerous spirit beings.
There could be a repeat of this astronomical double-act as a lunar eclipse will be visible across Australia on Saturday April 4, 2015.
Will the aurorae continue? Keep watch.

Finding meteorite impacts in Aboriginal oral tradition


Imagine going about your normal day when a brilliant light races across the sky. It explodes, showering the ground with small stones and sending a shock wave across the land. The accompanying boom is deafening and leaves people running and screaming.
This was the description of an incident that occurred over the skies of Chelyabinsk, Russia on February 15, 2013, one of the best recorded meteoritic events in history. This airburst was photographed and videoed by many people so we have a good record of what occurred, which helped explain the nature of the event.


But how do we find out about much older events when modern recordings were not available?
A century before Chelyabinsk, a similar event occurred on July 30, 1908, over the remote Siberian forest near Tunguska.
That explosion was even more powerful, flattening 80 million trees over an area of 2,000 square kilometres and sending a shock wave around the Earth – twice. It was 19 years before scientists reached the Tunguska site to study the effects of the blast.

The apparent lack of a meteorite fuelled speculation about how it formed, from sober suggestions of an exploding comet to more outlandish claims of mini-black holes and crashed alien spacecraft (research confirms it was an exploding meteorite).

Meteoric events in Indigenous oral tradition

In 1926, the ethnographer Innokenty Suslov interviewed the local Indigenous Evenk people, who still vividly remembered the Tunguska airburst.
At the time, a great feud persisted among Evenki clans. One clan called upon a shaman named Magankan to destroy their enemy. On the morning of July 30th, 1908, Magankan sent Agdy, the god of thunder, to demonstrate his power.

Many Indigenous cultures attribute meteoritic events to the power of sky beings. The Wardaman people of northern Australia tell of Utdjungon, a being who lives in the Coalsack nebula by the Southern Cross.
He will cast a fiery star to the Earth if laws and traditions are not followed. The falling star will cause the earth to shake and the trees to topple.
Like the Evenki, it seems the Wardaman have faced Utdjungon’s wrath before.
The Luritja people of Central Australia also tell of an object that fell to Earth as punishment for breaking sacred law. And we can still see the scars of this event today.

A surviving meteorite impact legend

Around 4,700 years ago, a large nickel-iron meteoroid came blazing across the Central Australian sky. It broke apart before striking the ground 145km south of what is now Alice Springs.
The fragments carved out more than a dozen craters up to 180 meters across with the energy of a small nuclear explosion.
Today, we call this place the Henbury Meteorites Conservation Reserve.

Aboriginal people have inhabited the region for tens-of-thousands of years, and it’s almost certain they witnessed this dramatic event. But did an oral record of this event survive to modern times?
When scientists first visited Henbury in 1931, they brought with them an Aboriginal guide. When they ventured near the site, the guide would go no further.
He said his people were forbidden from going near the craters, as that was where the fire-devil ran down from the sun and set the land ablaze, killing people and forming the giant holes.
They were also forbidden from collecting water that pooled in the craters, as they feared the fire-devil would fill them with a piece of iron.
The following year, a local resident asked Luritja elders about the craters. The elders provided the same answer and said the fire-devil “will burn and eat” anyone who breaks sacred law, as he had done long ago.

The longevity and benefits of oral tradition

The story of Henbury indicates a living memory of an event that occurred a few thousands of years ago. Might then we find accounts of events from tens of thousands of years ago?
Yes, it seems so.
Recent studies show that Aboriginal traditions accurately record sea level changes over the past 10,000 years.
Other studies suggest the volcanic eruptions that formed the Eacham, Euramo and Barrine crater lakes in northern Queensland more than 10,000 years ago are recorded in oral tradition.
In addition to demonstrating the longevity of Indigenous oral traditions, emerging research shows that these stories can lead to new scientific discoveries. Aboriginal stories about objects falling from the sky have led scientists to meteorite finds they would not have known about otherwise.
In New Zealand, geologists are also using Maori oral traditions to study earthquakes and tsunamis. New Zealand has a much more recent human history – compared to Australia – with the first Maori ancestors thought to have arrived around the 13th Century.
The arrival of the first Australians goes back at least 50,000 years. There is still much to learn, as Australia’s ancient landscape has been exposed to meteorite strikes that we don’t know about, some of which have probably occurred since humans arrived.
But given that Australia is home to the oldest continuing cultures on Earth, we are only just scratching the surface of the vast scientific knowledge contained in Indigenous oral traditions.
We anticipate that our work with Aboriginal elders to learn about Indigenous astronomy will lead to new knowledge and cultural insights about natural events and meteorite impacts in Australia.
