KNN Science Desk | November 3, 2026 — Astronomers studying 37 nearby dwarf galaxies have found that much of the oxygen their stars are expected to produce is not retained inside the galaxies. NASA described the result November 2, citing research published that day in The Astrophysical Journal.
Following the chemical record of stars
Oxygen is made by stars and serves as a useful tracer of how galaxies manufacture and distribute heavier elements. Researchers in the Galaxies Losing Oxygen via Winds (GLOW) project examined stellar populations and their histories using archival Hubble observations and additional telescope data. The targets were selected partly because their nearness lets Hubble resolve individual stars.
The results suggest energetic outflows associated with massive stars and supernova explosions can carry material out of smaller galaxies more efficiently than models had predicted. The team has not yet established exactly where most of the missing oxygen now resides: it could remain in gas around the galaxies or have traveled farther into intergalactic space.
What this finding changes
Understanding material lost by galaxies helps explain how galaxies grow, change their chemical makeup and enrich the space between them. Future studies may examine smaller and fainter systems, including candidates located with the Nancy Grace Roman Space Telescope. A sample of 37 nearby galaxies can test models, but it does not establish the behavior of every galaxy in the universe.
A philosophical comparison with the Book of Maat
The 2018 Book of Maat, in The Seven Principles of Maat (printed p. 156), presents the Principle of Correspondence as a philosophical way to think about relationships among levels of existence. Astronomy likewise examines relationships between individual stars, galaxies and their environments—but by measuring physical processes. This is a thematic comparison, not scientific confirmation of a spiritual principle or evidence that the text anticipated supernova chemistry.
