Level 1 — Absolute Beginner
Scientists used a big space telescope named James Webb.
They found a strange new kind of object in space.
People call it a black hole star.
It has a black hole hiding inside a big cloud of gas.

Level 2 — Elementary
Astronomers using NASA's James Webb Space Telescope have found a new kind of object in space, nicknamed a black hole star.
The object is called MoM-BH*-1, and it lies in the direction of the constellation Cetus. It is seen as it existed about 660 million years after the Big Bang, making it one of the earliest objects of its kind ever observed.
A black hole star is a huge, glowing cloud of hydrogen gas that surrounds and hides a rapidly growing black hole at its center. Scientists think it may be a young black hole wrapped inside an extremely thick blanket of hydrogen gas.
This discovery is connected to a bigger mystery. The Webb telescope has often spotted small, reddish objects in the early universe called little red dots, and scientists have long debated what they really are.

Level 3 — Intermediate
Astronomers using NASA's James Webb Space Telescope have identified a previously unseen kind of astrophysical object, nicknamed a black hole star, catalogued as MoM-BH*-1.
The object lies in the direction of the constellation Cetus and is seen as it existed roughly 660 million years after the Big Bang, making it one of the earliest such objects ever observed. The finding was published and announced around August 13, 2026.
A black hole star is described as an enormous, glowing cloud of hydrogen gas surrounding and hiding a rapidly growing, or accreting, black hole at its center, combining the star-like glowing appearance of a dense stellar atmosphere with the enormous energy output of an actively feeding black hole. Researchers believe it may represent a young black hole buried inside an extraordinarily dense envelope of hydrogen gas.
The discovery is linked to a broader mystery. Webb has repeatedly spotted strange, extremely compact, reddish objects in the early universe nicknamed little red dots, whose true nature astronomers have long debated. A study published in June 2026 identified 241 candidate black hole star sources across Webb's observations, suggesting the phenomenon is not a single freak occurrence but a broader class of object.

Level 4 — Advanced
Astronomers working with NASA's James Webb Space Telescope have identified a previously unseen class of astrophysical object, informally dubbed a black hole star, catalogued as MoM-BH*-1, whose discovery was published and publicly announced around August 13, 2026.
The object lies in the direction of the constellation Cetus and is observed at a lookback time corresponding to roughly 660 million years after the Big Bang, rendering it among the earliest such objects yet documented. Researchers describe it as an enormous, glowing envelope of hydrogen gas enshrouding a rapidly accreting black hole at its core, a configuration that fuses the star-like luminous profile of a dense stellar atmosphere with the prodigious energy output characteristic of an actively feeding black hole.
The prevailing interpretation holds that MoM-BH*-1 represents a nascent black hole cocooned within an extraordinarily dense envelope of hydrogen gas, a structure that would obscure direct observation of the accretion process itself while still permitting its enormous luminosity to escape. The finding bears directly on a longstanding puzzle in the field: the true nature of the compact, reddish sources Webb has repeatedly detected in the early universe, colloquially termed little red dots, whose classification astronomers have debated since their discovery.
A study published in June 2026 catalogued 241 candidate black hole star sources across Webb's observations, indicating that the phenomenon constitutes a broader population rather than an isolated anomaly. Scientists suggest that black hole stars such as MoM-BH*-1 may help resolve one of astronomy's most persistent open questions, namely how supermassive black holes attained masses a billion times that of the sun so soon after the Big Bang, at growth rates that substantially outpace what standard models of black hole accretion predict.
