A month ago this column looked at MoM-BH\-1, the single object that a team led by Rohan Naidu (MIT / University of Hawaiʻi) had just named in the pages of Nature* on 12 August 2026, and noted that the field had not picked a side about what JWST's Little Red Dots actually are. The piece finished by sitting in the tension rather than resolving it, which was the honest move at the time. It is no longer the honest move.
The August Nature paper — A gas-enshrouded and gas-reddened black hole at cosmic dawn (Naidu et al., Nature 656, 329–333; arXiv:2503.16596) — named a single object, roughly the size of the solar system, roughly 100 billion times brighter than the Sun, sitting at about 660 million years after the Big Bang, and argued, on the strength of a 30-hour Webb spectrum, that what we are looking at is a black hole of around 100,000 solar masses wrapped in a hydrogen envelope so dense it looks like the surface of an enormous star. The companion commentary by Schleicher and Herrera-Camus in the same issue makes the same point in a different register: the Little Red Dots get their colour from gas, not dust. A Nature paper from 14 January 2026 by Rusakov, Watson and colleagues (Nature 649, 574–579) had already been reading the dots the same way — as young supermassive black holes inside dense ionised cocoons — and the August paper reads, in retrospect, like the most photogenic specimen of an idea that had already arrived.
Three 2026 papers is a small enough number to put in a table:
| Date | Source | Key claim |
|---|---|---|
| 14 Jan 2026 | Rusakov et al., Nature 649 | LRDs are young SMBHs inside dense ionised cocoons |
| 12 Aug 2026 | Naidu et al., Nature 656 (MoM-BH\*-1) | One LRD isolated to its gas-wrapped accreting-black-hole component; every LRD is consistent with this, mixed with a young host |
| 12 Aug 2026 | Schleicher & Herrera-Camus, Nature 656 (commentary) | The red colour is gas scattering, not dust reddening |
This is not "the field has stopped debating." It is "the field has picked a side, but the side is internally various." The Jan 2026 paper reads the dots as black holes cocooned in ionised gas. The August Naidu paper reads MoM-BH\*-1 as a black hole cocooned in neutral hydrogen so dense it behaves like a stellar surface — a different cocoon. A third thread, the simulation work from September 2026 summarised in the research-news pipeline, treats the cocoon as the natural outcome of extreme radiation during seed formation; the picture there is of black holes growing so fast in such dense gas that the gas itself becomes part of what you see. All three say "accreting black hole." None of them say "the same accreting black hole in the same wrapping." That distinction is what the next few years of JWST time are going to settle.
The bit worth sitting with is what "picking a side" actually means here in late 2026. In 2024, picking a side meant choosing between "ancient black holes in overdrive" and "early-universe galaxies at extreme redshift," and the answer was unclear. In 2026, picking a side means choosing between three or four flavours of accreting black hole, all of which assume the black hole is the engine and the question is what is wrapped around it. The controversy has moved. It has not ended. What has ended is the older version of the question, which is now roughly as live as the question of whether Pluto is a planet — a question the field has answered by getting bored with it and moving on.
The remaining open questions are technical and concrete. How does the seed form, given that a 100,000-solar-mass object at 660 million years after the Big Bang does not leave much time for accretion? What fraction of the LRD phase is "duty-cycled" — that is, how long does a typical galaxy spend looking like MoM-BH\*-1 before it evolves into something bluer? And what share of the total supermassive-black-hole mass budget at z > 4 is contributed by objects in this phase, as opposed to the more familiar unobscured quasars? The JWST archive holds roughly 300 LRD spectra; the next 30-hour observation will not be on a single object, but on the population, and the answer to all three questions is sitting in that data, waiting for someone to extract it.
The "field hasn't picked a side" framing is, in other words, stale. The field has picked a side. The side is internally various. Picking a side in 2026 means something different than it did in 2024, and the 8/15 piece, written before the August paper landed in a journal, was not wrong to flag the uncertainty then; it is just behind the curve now, and so is anyone reading it as the live state of the question.
