An international team of scientists says it has identified the reason star formation across the universe has slowed down, according to the News Agency of Nigeria. The agency reported the finding on Friday, 11 September 2026.
The work addresses a puzzle that has drawn attention in astronomy: the universe still holds large amounts of the material needed to build stars, yet it is making fewer of them. SciTechDaily framed the same question in its own coverage, asking why a cosmos with abundant fuel is producing a declining number of stars.
According to the News Agency of Nigeria, the explanation comes from researchers working across international borders, though the agency's headline did not name the institutions or individuals involved.
The reports point to a gap between the supply of star-forming material and the rate at which new stars actually appear. Star formation depends on cold gas clouds collapsing under gravity, and the new finding concerns why that process appears to be running slower than the available fuel alone would suggest.

Both outlets presented the result as a step toward explaining a long-observed decline in the universe's output of new stars. The News Agency of Nigeria described the discovery as uncovering the reason behind the slowdown, while SciTechDaily highlighted the contrast between plentiful fuel and reduced star production.
Further details of the study, including the methods used and where it was published, were not included in the material available.
What to watch next: whether the research team releases full findings and whether other astronomers confirm the proposed explanation.
