Level 1 - Absolute Beginner
The James Webb Space Telescope looks deep into space. It can see very old and very far away objects.
Scientists found something strange. It looks like a giant star, but it is much too bright to be a real star.
Scientists gave it the name MoM-BH*-1. They think it might be a black hole wrapped in a thick cloud of gas.
The object comes from a time just a few hundred million years after the universe began. Scientists call it a black hole star.

Level 2 - Elementary
Astronomers using the James Webb Space Telescope have discovered a bizarre object dating from just a few hundred million years after the Big Bang. It looks like an enormous star, but it shines far too brightly to actually be one.
The object, named MoM-BH*-1, was found in one of the deepest fields ever observed by Webb. It first appeared as a bright red point with an extremely unusual color, almost invisible through Webb's blue filters but very visible in red light.
Scientists believe the object may contain a black hole about one hundred thousand times the mass of the Sun, surrounded by a dense, star-like cocoon of hydrogen gas roughly the size of our solar system.
The object's brightness appears to have increased by about thirty percent over roughly two months, a pattern that matches what scientists would expect from a black hole actively feeding on the gas around it.

Level 3 - Intermediate
Astronomers using the James Webb Space Telescope have identified an anomalous object dating to just a few hundred million years after the Big Bang, one that superficially resembles an enormous star yet radiates far more luminosity than stellar physics would permit.
Designated MoM-BH*-1, the source emerged within one of Webb's deepest observed fields and displayed an extraordinarily unusual color profile from the outset, appearing nearly undetectable through the telescope's bluer filters while registering as one of the reddest distant sources ever catalogued in redder wavelengths.
Researchers now propose the object harbors a black hole of roughly one hundred thousand solar masses, enveloped within a dense, star-like cocoon of hydrogen gas approximately the size of our solar system, a configuration that would account for both its stellar appearance and its anomalous brightness.
Reinforcing this interpretation, the object's luminosity climbed by approximately thirty percent over a span of roughly two months, a variability signature consistent with an actively accreting black hole, and one that positions MoM-BH*-1 within the broader category of unexplained early-universe sources known as little red dots.

Level 4 - Advanced
Astronomers deploying the James Webb Space Telescope have identified an anomalous source dating to merely a few hundred million years after the Big Bang, one that superficially mimics an enormous star yet radiates luminosity far exceeding what conventional stellar physics would sanction.
Designated MoM-BH*-1, the source surfaced within one of Webb's deepest observed fields and exhibited an extraordinarily aberrant color profile from the outset, registering as nearly undetectable through the telescope's bluer filters while emerging as one of the reddest distant sources ever catalogued at longer wavelengths.
Researchers now posit that the object harbors a black hole of approximately one hundred thousand solar masses, ensconced within a dense, star-like cocoon of hydrogen gas roughly commensurate in scale with our solar system, a configuration that would reconcile both its stellar morphology and its anomalous luminosity.
Corroborating this interpretation, the object's brightness escalated by approximately thirty percent across a span of roughly two months, a variability signature consistent with an actively accreting black hole, situating MoM-BH*-1 within the broader, still poorly understood taxonomy of early-universe sources colloquially termed little red dots.
