Astronomers May Not Like It but Astronomy and Colonialism Have a Shared History

Casting Native Hawai’ians’ opposition to the Thirty Meter Telescope atop Mauna Kea as a contest between science and religion is a red herring that distracts from a deeper problem with modern science.

Mauna Kea, an extinct volcano in Hawai’i, has been the site of a long-running conflict. Native Hawaiians who consider Mauna Kea sacred have been at odds with the international consortium of astronomers behind the $1.4-billion Thirty Meter Telescope (TMT), meant to be “the largest ground-based observatory in the world” (source). Now, a white paper by Native Hawaiian scientists calls for an immediate halt to the TMT’s construction and for restarting dialogue. An associated paper by five US and Canadian astronomers situates the TMT controversy in the long history of how astronomy has benefited from “settler colonial white supremacist patriarchy” and calls on the astronomy community to reject these benefits.

This may seem an unlikely combination of charges against fellow astronomers who simply wish to “reach back 13 billion years to answer fundamental questions about the advent of the universe” (source) – until one takes a closer look at the conflict, moving beyond its unhelpful framing as science versus religion and situating it in its historical context.

“At its core, [the conflict over] Mauna a Wākea is about power,” writes Iokepa Casumbal-Salazar, who studied the TMT controversy for his doctoral thesis at the University of Hawaiʻi at Mānoa in 2017. “How are we to understand the controversy over Mauna a Wākea and the TMT if we fail to identify or accept the context in which this battle is being waged; if we fail to critically analyse settler-colonisation under US occupation?” Casumbal-Salazar is now an assistant professor at the Center for the Study of Culture, Race and Ethnicity at Ithaca College, New York.

The story of TMT in Hawai’i began in 2009, when the collaboration of scientists building the observatory selected Mauna Kea as the location. The summit, at about 4,200 m above sea level, is particularly conducive for astronomy, with stable, dry air that allows observations throughout the year. As a result, it is already host to 13 observatories that have been built since the 1960s.

Preparations for TMT’s construction began in 2014 but were paused following opposition from Native Hawaiians – “protestors” to the state and the astronomers, “protectors” for the activists. In December 2015, the Supreme Court of Hawai’i invalidated the TMT’s 2011 construction permit because it had been granted before the opposition’s petitions had been addressed – putting, as the verdict observed, “the cart before the horse”.

In October 2018, the Supreme Court gave the go-ahead and construction was to resume in July 2019. But Native Hawaiians have continued opposing the TMT by blocking access to the mountain and courting arrest. In December 2019, the Governor of Hawai’i announced that “the state will reduce its law enforcement personnel on Maunakea”, an admission that the project cannot be forced through. (India, a partner and full member of the TMT consortium, prefers moving the telescope to an alternate location in the Canary Islands, Spain.)

That’s the legal summary. For a historically informed understanding of the conflict, we have to go back much further, to Hawaii’s annexation by the US in 1898, following which land was ceded to the US government.

In 1959, these lands – including Mauna Kea – were in turn ceded by the US government to the State of Hawai’i, which held them “in trust” for native Hawaiians. The next year, a tsunami laid waste to the city of Hilo in Hawai’i, prompting its chamber of commerce to write to universities in the US and Japan suggesting that Mauna Kea might be useful for astronomical observatories. This event coincided with US astronomers’ interest in Hawai’i as well.

And so the conflict between native Hawaiians and the American astronomy community began in the 1960s, when the first of the 13 observatories was constructed on the mountain that the former consider to be “a place revered as a house of worship, an ancestor, and an elder sibling in the mo’okū’auhau (or genealogical succession) of all Hawaiians.”

At the time, writes Casumbal-Salazar, “there was no public consultation, no clear management process and little governmental oversight.” Environmentalists soon began opposing further construction on the mountain, arguing that the existing telescopes had contaminated local aquifers and destroyed the habitat of a rare bug found only on the mountain’s summit.

Native Hawaiians joined forces with environmentalists, arguing that any construction on the summit is desecration of a sacred mountain that is the site of spiritual and cultural practices. “Indeed,” Casumbal-Salazar, whose ancestry is partly native Hawaiian, writes, “Mauna a Wākea is more than just a list of physical attributes; it is our kin. As our kupuna [ancestors] are buried in the soil, our ancestors become the land that grows our food and the dust we breathe.” Soon, native Hawaiians were required to seek permission from the state for spiritual practice on the mountain.

Contrary to the narrative that native Hawaiians did not oppose the first telescopes on Mauna Kea in the 1960s and 1970s, Casumbal-Salazar shows how they did indeed express their dissent “in the few public forums available, by writing newspaper editorials, publishing opinion pieces and speaking out at public events” while also fighting other battles, such as those to reclaim their rights to land, resources, cultural practices – even the right to teach their children in the Hawaiian language.

They were also fighting evictions and resettlements in the name of tourism development and decades of the US Navy’s use of an island as target practice for its bombs. At the same time, the state’s dependence on tourism and militarism resulted in income inequalities and emigration.

Mauna Kea is not the only mountain in the US where native communities and astronomers have clashed. Two telescopes on mountaintops in Arizona became controversial for parallel reasons, beginning from the mid-1970s, as Leandra Swanner examines in her doctoral thesis at Harvard University. Environmental groups opposed the Mt Graham International Observatory in Arizona fearing ecological damage and further threat to the endemic Mt Graham red squirrel, joined later by a community of native Americans for whom the summit had spiritual significance as a prayer site.

Similarly, native communities and environmentalists opposed the Kitt Peak National Observatory in Arizona, concerned about the ecology and “spiritual integrity” of the mountain. At the time the new observatory was proposed, Kitt Peak was already host to two dozen telescopes.

Strikingly, Swanner tracks how native groups at these three different sites have “independently framed the observatories as colonialist projects”. She finds that astronomers, native communities and environmental groups “deployed competing cultural constructions of the mountains – as an ideal observing site, a ‘pristine’ ecosystem or a spiritual temple,” and that “the timing and form of anti-observatory narratives was historically tethered to the legal and political strength of environmental and indigenous rights movements.” In the case of the conflict at Mauna Kea, this is the nationalist movement known as the Hawaiian Renaissance.

Sustained opposition to construction on Mauna Kea led in 1998 to a state legislative audit that indicted the University of Hawai’i for its management of the mountain, citing inadequate measures to protect its natural resources and lack of recognition of its cultural value. In 2000, the University of Hawai’i drafted a ‘master plan’ for activities on the mountain, which empowered native Hawaiians to voice their objections to the observatories formally, eventually leading to the current impasse.

Swanner finds that for native Hawaiians, “science has effectively become an agent of colonisation”, “fundamentally indistinguishable from earlier colonisation activities”. This puts astronomers in a difficult position. They see the economic benefits astronomy brings to Hawai’i – over a thousand jobs, business for local firms and services and, once the TMT comes online, a promise to pay $1 million in annual lease rent – and their own work as a noble pursuit of knowledge. However, they encounter opposition that has charged them with environmental and cultural destruction.

“Unfortunately for the astronomers involved in the TMT debate,” writes Swanner, “whether they identify as indigenous allies or neocolonialists ultimately matters less than whether they are perceived as practicing neocolonialist science” (emphasis in the original).

Astronomers have attempted a counter-narrative, linking the contemporary practice of astronomy to ancient Polynesian explorers and astronomers who navigated using the stars. A concrete outcome and centrepiece of this effort was a science education centre and planetarium that “links to early Polynesian navigation history and knowledge of the night skies, and today’s renaissance of Hawaiian culture and wayfinding with parallel growth of astronomy and scientific developments on Hawaii island.”

Swanner notes the unequal relationship – the centre “merely grafts Native Hawaiian culture onto the dominant culture of Western science … Astronomers do not look to traditional knowledge to carry out their observing runs, after all, but the observatories studding the summit physically deny access to sites of sacred importance.”

For Casumbal-Salazar, this strategy of linking telescopes on the mountain to ancient Hawaiian culture reinterprets colonial conquest as inheritance while consigning indigeneity to history. This is not hard to spot from a glance at the TMT website, for example. The homepage displays the results of a “statewide scientific public opinion poll” which asked, among others, the following question: “Do you agree or disagree that there should be a way for science and Hawaiian culture to co-exist on Maunakea?” The way the question has been framed is revealing: science and Hawaiian culture are seen as distinct entities.

The conflict at Mauna Kea, as Swanner and Casumbal-Salazar learn from native Hawaiians, is not just over the construction of the TMT. The problem is that anything is being built on top of a sacred summit. Nevertheless, it is not incidental that the conflict involves science, particularly astronomy. Science did not merely happen to accompany colonialism: they are deeply linked in ways that are still being unraveled by historians who are tracing “the roots of contemporary science in the projects and practices of colonialism,” filling in the elisions from standard histories of science.

In their white paper, Chanda Prescod-Weinstein, an American-Barbadian cosmologist at the University of New Hampshire, and her co-authors give examples of how colonial conquests have historically enabled, facilitated or benefited astronomy. James Cook, the British explorer who was the first European to establish contact with Hawai’i, was tasked with leading an expedition to Tahiti to observe the 1769 transit of Venus (to help determine the Earth-Sun distance). But he had also been given sealed orders to search for Australia, indicating “that astronomy and colonisation have been entwined in the Pacific since first contact.”

Colonial conquests helped develop astronomy and cartography, not least through the establishment of overseas observatories. Other sciences “co-constituted” with colonialism include botany and medicine. And, as one author reviewing the existing scholarship put it: “One cannot imagine Charles Darwin’s work being possible without his access to plant and animal specimens derived from several European empires.” Science and medicine “functioned not merely as a ‘tool’ for a project already imagined, but as a means of conceptualising and bringing into being the colonial project itself.”

This history has consequences – not because the TMT is “a pawn in a long, losing game” for the Hawaiians (as one condescending New York Times article phrased it) nor is the issue confined to questions of representation of colonised peoples in astronomy (although only one Native Hawaiian holds a PhD in astronomy, with none in tenure-track positions at major institutions). For Casumbal-Salazar, it is about how “Western law, science and the state together control the ways humanity is imagined in the first place” and about “the techniques of governance by which Kanaka ‘Ōiwi [native Hawaiian] claims to land, sovereignty and independence remain in perpetual deferral.”

This settler colonialism, he argues, is the product of a sustained process with territorial ambitions. As Swanner notes, dismissing this neocolonialist image of science has only resulted in native communities continuing to “report feeling victimised while scientists’ efforts to expand their research programs suffer social, legal and economic setbacks.”

In response, astronomy practice is changing. In her thesis, Swanner tracks how the opposition to mountaintop observatories and the rigours of preparing an environmental impact statement have forced astronomers to directly engage with the public and acknowledge their concerns.

Prescod-Weinstein and her coauthors go further, advancing a number of recommendations for a more ethical astronomy. For example, they call on the astronomy community to stop weaponising disagreements within native communities, which they have a history of doing. At Kitt Peak, for example, leaders of a native community signed a lease agreement in 1958 after they were invited to view the sky through one of the telescopes of the University of Arizona, even as others in the community remained unconvinced. Such tactics led the community to feel their interests weren’t fairly represented. They filed a lawsuit against the National Science Foundation fifty years later.

Prescod-Weinstein and her colleagues also recommend that “astronomers reject the use of state power to get what they want”, “consider what is globally healing for the communities rooted in the land” and “engage in dialogue and negotiations in good faith, understanding that a deal may not be reachable, with a mandate to respect a ‘no deal’ outcome.” The paper by Native Hawaiian scientists also recommends the same things, and asks: “Do indigenous people have the power to decide what happens to their own homelands?”

At Mauna Kea, this means understanding that Native Hawaiians, from the beginning of the opposition to telescopes on the mountain, “were not fighting against something,” as Casumbal-Salazar notes, “so much as they were fighting for something: the protection of the mountain from further development… Perhaps we should be asking what constitutes progress. Who determines that? And what are the costs of its production?”

India Wants Thirty-Metre Telescope Shifted Out of Hawaii

India has committed 10% of the project’s resources, a sum of about Rs 1,423 crore.

Once it is built, the Thirty-Meter Telescope (TMT) will become one of the world’s largest general-purpose observatories, allowing astronomers to study the outer reaches of the universe and study distant stars and exoplanets than much greater detail than is currently possible.

The problem is that it is not getting built because the proposed site for the TMT, atop the dormant Mauna Kea volcano in Hawaii, is also a sacred location for the island’s native population. The latter have been protesting the telescope’s construction since 2014. In 2018, the Supreme Court of the State of Hawaii allowed construction to proceed. However, protestors forced construction to stop once again in 2019.

Today, The Hindu reported that India – a member of the international collaboration of research institutions and national governments that have committed money and other resources to building the TMT – wants the observatory to be shifted to a different site, away from Mauna Kea.

India has committed 10% of the project’s resources – a sum of about $200 million (Rs 1,423.46 crore) – and Indian scientists are in turn guaranteed 10% of observation time on the TMT once it is ready.

Prior to picking Mauna Kea, the international collaboration had prepared a shortlist of five sites, including one in Hanle, Ladakh, where the Indian Astronomical Observatory is also located. Mauna Kea came out on top because it offers better viewing conditions for astronomers; on the other hand, Hanle is located close to the India-China border and is a high-security area with tightly controlled access.

Ashutosh Sharma, the secretary of the Department of Science and Technology, told The Hindu, “India’s position has been clear. We would like the project to move to an alternate site if all the procedures and permits there are in place.”

He added that even if the current negotiations with the native population succeeds and construction resumes, the threat of future protests still exists. The telescope was originally expected to be ready by 2025; the more this date is delayed, the less time the telescope will have to achieve its scientific objectives, which in turn will reduce the amount of time available for each country’s scientists.

The next most favourable location on the shortlist is the Roque de los Muchachos Observatory in the Canary Islands, which belong to Spain. The representatives of various institutions of the collaborations are set to meet in Los Angeles in February to deliberate on this and other issues.

Roadshow Brings Mega Science Projects to the People

The show focuses on seven mega-science projects supported by countries around the world, including India.

Mumbai: An 11-month long and nationwide roadshow to create a buzz around various international mega-science projects devoted to understanding the working of the universe from the atomic to the astronomical level rolled out in Mumbai on May 8.

The programme is named Vigyan Samagam and is being executed in the form of a travelling exhibition that features galleries of posters, working models, exhibits, audio-visuals informational materials, electronic displays and interactive kiosks.

The first destination was Mumbai’s Nehru Science Centre, where the show plans to stay for two months, until July 7. It will then move to Bengaluru, where it will be open to the public from July 29 to September 28 at the Visvesvaraya Industrial and Technological Museum.

The next stop will be Kolkata, where it be open at the Science City from November 4 to December 31. The final stop will be at the National Science Centre in New Delhi from January 21 to March 30 next year.

The exhibitions will be open on weekends and holidays as well, from 10 am to 6 pm.

The show focuses on seven mega-science projects supported by countries around the world, including India. They are the European Organisation for Nuclear Research, Switzerland; the India-based Neutrino Observatory, Tamil Nadu; the Facility for Antiproton and Ion Research, Germany; the International Thermonuclear Experimental Reactor, a fusion reactor in France; the Laser Interferometer Gravitational Wave Observatories in the US and on the one being planned in India; the Thirty Meter Telescope; and the Square Kilometer Array, South Africa.

These projects throw light on crucial questions related to the origin of the universe and its evolution through its various stages. They relate to particle physics, including properties of particles like the Higgs boson and neutrinos, the detection of gravitational waves from colliding black holes and merging neutron stars, and precision engineering challenges involving the containment of extremely energetic plasmas.

Among other things, the programme will highlight India’s contributions in these research and development activities.

The inaugural event at each venue will be followed two days of events comprising talks and lectures by eminent speakers from research and industry. These will be live-streamed through social media platforms.

Its organisers – the Departments of Science and Technology and Atomic Energy and the National Council of Science Museum (NCSM) – will also conduct quizzes, essay writing contests, drawing contests and science awareness cyclothons to engage schoolchildren and other students in attendance.

V.K. Saraswat, a member of NITI Aayog, emphasised the importance of science and technology for the country’s economic growth of the country in his launch speech, and hoped that the programme will help to inspire youth to take up scientific work as a career.

K. VijayRaghavan, the principal scientific adviser to the Government of India, spoke of the need to make scientific and technological developments available in local languages to ensure they are accessible to more people (an issue he has discussed before in some detail).

A.D.Choudhary, the director-general of the NCSM, said the organisation was working on a plan to expand the show’s footprint to include smaller cities as well.

Size Matters: For Disruptive Science, Make Research Teams Smaller, Not Bigger

A new study says that small teams are more likely to start new scientific conversations, while large teams largely build on existing work.

New Delhi: While a number of famous, well-funded scientific projects in recent years – LIGO being a good example – have prided themselves on having large, collaborative teams, a new study suggests that may not be the best way to conduct research.

A study by Lingfei Wu, Dashun Wang and James A. Evans, published in the journal Nature, has found that scientific research conducted by smaller teams tends to be more “disruptive” than the work of larger groups.

‘Disruptive’ science

The authors looked at over 65 million scientific papers, patents and software projects from the last 60 years, and found that the work of smaller teams was more likely to take scientific conversation in an entirely new direction. Larger teams, on the other hand, were more likely to build on pre-existing findings, rather than a formulate altogether new theories.

Work from larger teams builds on morrecent and popular developments, and attention to their work comes immediately. By contrast, contributions by smaller teams search more deeply into the past, are viewed as disruptive to science and technology and succeed further into the future—if at all,” the authors note.

The authors uses citations to calculate the “disruption score” of a study. When citing a study, such as Einstein’s 1915 papers on general relativity, have future researchers felt the need to go back to papers that author of the study cited? If not, the researchers argue, it suggests that the study took the scientific conversation in a new direction.

“They see it [Einstein’s papers] as a conceptually new direction that’s distinct from the things on which it built,” co-author Evans told The Atlantic. On the other hand, if scientists “think that something is an incremental improvement, they’ll tell the whole story in the references.”

This isn’t the first time studies have highlighted the importance of small research teams. A study by Staša Milojević published in 2015 found that “articles produced by larger teams cover significantly smaller cognitive territory than (the same quota of) articles from smaller teams”. According to her, big-team researchers end up focusing only on a small range of topics, whereas lone researchers and small teams cover a wider range of scientific areas.

Despite these previous results, the romanticisation of research conducted by large teams has not gone away. The work by Wu, Wang and Evans should “temper some of that enthusiasm for large teams and demonstrate that there may be a tipping point after which their benefits decline”, Erin Leahey from Arizona State University told The Atlantic.

Explaining the results

The authors of the study did not find evidence that small teams do more theoretical work, or that the more “groundbreaking” scientists prefer to work in smaller teams. “Instead, [the authors] found that large teams tend to build on recent, prominent work, while small teams delve more deeply into the past, drawing inspiration from older ideas that may have long been ignored,” The Atlantic reported.

Suparna Rajaram, a professor of psychology at Stony Brook University, told the New York Times that the results are in line with psychological research. “We find that the product of three individuals working separately is greater than if those three people collaborate as a group. When brainstorming, people produce fewer ideas when working in groups than when working alone.”

While there may be long-term benefits to collaboration, Rajaram said, “overall, this new study provides findings on a large scale that are consistent with the underlying principles of our work”.

It’s not just researchers who behave in this manner. Firms too are often more disruptive when smaller – and research teams have come to resemble firms in several ways. “This study is evidence that the ecology of science and the ecology of innovation are becoming very similar,” You Na Lee, who studies scientific innovation at the National University of Singapore, told The Atlantic.

But there’s an important difference. Small start-ups are actively encouraged in the business world, whereas in terms of scientific research, large teams are more likely to be well funded. Co-author Evans has argued that this needs to change, given the important role small teams can play.

“In 10 years, we’ll be wondering where all the big ideas are,” he told The Atlantic. “Some people will wonder if science is slowing down and we’ve eaten all the low-hanging fruit. And the answer will be yes, because we’ve only built engines that do that.”

Note: This article was changed on February 15, 2019. The Large Hadron Collider as an example of a scientific project with “large, collaborative teams” was replaced with LIGO.

‘World Class’ Optical Telescope, and India’s Largest, to Be Activated near Nainital

The instrument is part of a widening foray into observational astronomy that India has undertaken since the 1960s, and bolstered with the successful launch of its first multi-wavelength satellite in September 2015.

New Delhi: India’s largest ground-based optical telescope, in Devasthal in Uttarakhand, will be switched on March 30 by the prime ministers of India and Belgium from Brussels, during Narendra Modi’s day-long visit to the country. The telescope is the product of an Indo-Belgian collaborative effort, assisted by the Russian Academy of Sciences, that was kicked off in 2007. It is going to be operated by the Aryabhatta Research Institute of Observational Sciences (ARIES), an autonomous research body under the Department of Science and Technology.

The instrument is part of a widening foray into observational research in astronomy that India has undertaken since the 1960s, and bolstered with the successful launch of its first multi-wavelength satellite (ASTROSAT) in September 2015. And apart from the merits it will accord Indian astronomy, the Devasthal optical telescope will also be Asia’s largest ground-based optical telescope, succeeding the Vainu Bappu Observatory in Kavalur, Tamil Nadu.

Its defining feature will be a 3.6-metre-wide primary mirror, which will collect light from its field of view and focus it onto a 0.9-m secondary mirror, which in turn will divert it into various detectors for analysis. This arrangement, called the Ritchey-Chrétien design, is also what ASTROSAT employs – but with a 30-cm-wide primary mirror. In fact, by contrast, the mirrors and six instruments of ASTROSAT all weigh 1,500 kg while the Devasthal telescope’s primary mirror alone weighs 4,000 kg.

A better comparison would be the Hubble space telescope. It manages to capture the stunning cosmic panoramas it does with a primary mirror that’s 2.4 m wide. However, Hubble’s clarity is much better because it is situated in space, where Earth’s atmosphere can’t interfere with what it sees.

Nonetheless, the Devasthal telescope is located in a relatively advantageous position for itself – atop a peak 2.5 km high in the Western Himalaya, 50 km west of Nainital. A policy review published in June 2007 notes that the location was chosen following “extensive surveys in the central Himalayas” from 1980 to 2001. These surveys check for local temperature and humidity variations, the amount of atmospheric blurring and the availability of dark nights (meeting some rigorous conditions) for observations. As the author of the paper writes, “The site … has a unique advantage of the geographical location conducive for astronomical observations of those optical transient and variable sources which require 24 h continuous observations and can not be observed from [the] east, in Australia, or [the] west, in La Palma, due to day light.”

From this perch, the telescope – held by ARIES to be of “world class” – will be able to log the physical and chemical properties of stars and star clusters; high-energy radiation emanating from sources like blackholes; and the formation and properties of exoplanets. The data will be analysed using three attendant detectors:

  • High-resolution Spectrograph, developed by the Indian Institute of Astrophysics, Bengaluru
  • Near Infrared Imaging Camera, developed by the Tata Institute of Fundamental Research, Mumbai
  • Low-resolution Spectroscopic Camera

“India has collaborated with a Belgian company called AMOS to produce this [telescope], which is the first of its kind in the whole of Asia,” said Vikas Swarup, spokesperson of the Ministry of External Affairs, in a statement. AMOS, an acronym for Advanced Mechanical and Optical Systems, was contracted in 2007 to build and install the mirrors. The assembly was readied in March 2015.

With Modi’s and Michel’s performance of the so-called ‘technical activation’ to turn the Devasthal instrument on, it will join a cluster of scopes at the Indian astronomical research community’s disposal to survey the skies at various wavelengths. Some of these other scopes are the Giant Metre-wave Radio Telescope, Pune; Multi Application Solar Telescope, Udaipur; MACE gamma-ray telescope, Hanle; Indian Astronomical Observatory, Leh; Pachmarhi Array of Cherenkov Telescopes, Pachmarhi; and the Ooty Radio Telescope, Udhagamandalam.

In fact, over the last few years, the Indian research community has positioned itself as an active player in international Big Astronomy. In 2009, it pitched to host a third advanced gravitational-waves observatory, following the installation of two in the US, and received governmental approval for it in February 2016. Second: in December 2014, India decided to become a full partner with the Thirty Meter Telescope (TMT) collaboration, a bid to construct an optical telescope with a primary mirror 30 metres wide. After facing resistance from the people living around the venerated mountain Mauna Kea, in Hawaii, atop which it was set to be built, there are talks of setting it up in Hanle. Third: in January 2015, the central government gave the go-ahead to build a neutrino observatory (INO) in Theni, Tamil Nadu. This project has since stalled for want of various state-level environmental clearances.

All three projects are at the cutting edge of modern astronomy, incorporating techniques that have originated in this decade, techniques that take a marked break from the conventions in use since the days of Galileo. That Modi has okayed the gravitational waves observatory is worth celebrating – but the choices various officials will make concerning the INO and the TMT are still far from clear.
