AI-Augmented Cosmic Cartography Reveals Gravitational Lenses—Unlocking Dark Matter’s Role in Galaxy Formation Through Decolonized Data Practices
Original framing: “Largest 2D map of the universe helps scientists discover new gravitational lenses” — Phys.org
The voices of global South astronomers, women scientists, and Indigenous researchers are systematically excluded from gravitational lensing narratives, despite their critical contributions. For example, the DESI Legacy Imaging Surveys, while global in scope, are led by U.S.-based institutions, with limited representation from African or Latin American researchers who operate telescopes in their regions. Women astronomers, who make up only about 30% of the field, are often sidelined in high-profile discoveries, as seen in the underrepresentation of female co-authors in gravitational lensing papers. Indigenous astronomers, who have historically documented celestial phenomena, are rarely consulted as experts in modern lensing research. Restoring marginalised voices would require structural changes, such as mandatory Indigenous collaboration in data interpretation and the establishment of global South-led research consortia to ensure equitable credit and funding for discoveries made with telescopes in their territories.

By centering Western institutions like DESI and ignoring the labor of global South observatories, the narrative obscures the colonial roots of astronomical data extraction—where telescopes in Chile, South Africa, and Hawaii are operated by Northern Hemisphere-led consortia while their local communities see minimal benefit. Indigenous cosmologies, which historically mapped celestial phenomena through oral traditions and spiritual frameworks, are erased in favor of a detached, quantitative approach that treats gravitational lenses as passive data points rather than active participants in cosmic narratives. The trickster dimension reveals the absurdity of celebrating 'new' discoveries while ignoring the centuries of uncredited work they build upon, from the 'Harvard Computers' to Fritz Zwicky’s dismissed hypotheses. Future pathways must prioritize decolonized data governance, global South-led AI hubs, and citizen science collaborations to ensure that gravitational lensing research becomes a tool for both scientific insight and social justice. The synthesis of Indigenous knowledge, historical precedents, and ethical AI frameworks could transform this field from a site of colonial extraction into a global commons where all voices—scientific and spiritual—are equally magnified.
