# JWST discoveries in the early universe and local cosmos > Live situation record from CLSTR: https://clstr.news/situations/james-webb-telescope-discoveries > Updated: 2026-09-09T02:57:02.000Z. Sources: 101. Developments: 26. Since late June 2026, JWST has delivered high-impact observations across cosmology, exoplanet atmospheres, and solar-system bodies. Key findings include the confirmation of the “magical line” in Abell 2744 and the detection of salt clouds on GJ 504b. In August 2026, research into the early universe’s “little red dots” evolved. Data identified a ‘Black Hole Star’ (MoM-BH-1*)—an object 100 billion times brighter than a normal star—which appears to be a supermassive black hole of roughly 100,000 solar masses enveloped in a dense hydrogen cocoon. This discovery, alongside a new census of the early universe, suggests galaxies formed earlier and grew faster than previous models predicted, though the ΛCDM cosmological framework remains intact. Further studies of the distant galaxy J0148-4214 revealed a unique triplet of active supermassive black holes. Mapping efforts have expanded significantly. Using the Cosmic Evolution Survey (COSMOS), astronomers produced a highly detailed map of the dark matter cosmic web, covering an area 2.5 times the size of a full moon. By analyzing light bending from approximately 800,000 galaxies, researchers confirmed that dark matter acts as “gravitational scaffolding” and has coexisted with visible matter since the early universe. Recent observations of local environments and planetary formation have also yielded breakthroughs. Using its Mid-Infrared Instrument (MIRI), astronomers identified dust and water molecules surrounding the star IRS 3 near Sagittarius A*, demonstrating that such molecules can persist in high-radiation environments. In exoplanet research, JWST detected the spectral signature of heavy water (HDO) in the atmosphere of WASP-39b, marking the first verification of water isotopologues outside our solar system. Additionally, a study of 72 protoplanetary disks revealed that gas giant formation is a race against time; gas is lost through distinct stages, moving from magnetic field-driven jets to atomic winds driven by photoevaporation, eventually closing the window for gas-rich planet formation. ## Claims - Research led by Naman Bajaj from the University of Arizona studied 72 young, Sun-like stars and their protoplanetary disks.
