James Webb Space Telescope reveals early universe mysteries
Astronomers using the James Webb Space Telescope (JWST) have identified a unique cosmic object in the early universe, approximately 660 million years after the Big Bang, dubbed a ‘black hole star’. The object, named MoM-BH-1*, appears to be a supermassive black hole—roughly 100,000 times the mass of the Sun—enveloped in a massive, dense cocoon of hydrogen gas. This structure is larger than our Solar System and shines with the luminosity of 100 billion Suns, potentially explaining the mysterious ‘little red dots’ observed in deep-space surveys.
In a separate discovery, JWST observations have detected water vapor and silicate dust surrounding IRS 3, an aging star located just 0.55 light-years from Sagittarius A*, the supermassive black hole at the center of the Milky Way. The presence of these molecules challenges previous scientific assumptions that the intense radiation near the galactic core would prevent the formation and survival of such materials.
Additionally, four years of JWST data have provided a new census of the early universe, revealing that galaxies formed earlier, grew faster, and appeared more frequently than many pre-Webb cosmological models predicted. While these findings challenge specific assumptions regarding star formation and galaxy evolution, they have not yet falsified the overarching ΛCDM cosmological framework.
