US EditionWebb Sees the Galaxies that Cleared Out the Cosmic Fog
- On June 11, 2025, researchers announced the detection of 83 small starburst galaxies within the Abell 2744 cluster, identified through observations made with the James Webb Space Telescope.
- Researchers targeted Abell 2744, or Pandora's Cluster, using JWST's infrared vision to study galaxies from when the universe was 800 million years old.
- These tiny, energetic galaxies produce abundant ultraviolet light, suggesting they played a key role in reionizing the early universe and clearing cosmic fog.
- Isak Wold explained that these diminutive galaxies generate a surprisingly large amount of ultraviolet light, enough to fuel significant changes in the cosmos, a conclusion supported by recent JWST observations.
- This discovery supports the theory that numerous small galaxies powered the Era of Reionization, transforming the cosmos from dark and foggy to bright and transparent.

Webb Telescope Unveils 83 Starburst Galaxies That Rewrite Cosmic History
Webb discovered dozens of small, powerful galaxies from 800 million years ago that likely drove cosmic reionization by emitting strong ultraviolet radiation. Astronomers using data from NASA’s James Webb Space Telescope have discovered dozens of small galaxies that played a key role in reshaping the early universe into its present form. “When it comes to [...]
Webb sees the galaxies that cleared out the cosmic fog
Scientists using NASA's James Webb Space Telescope (JWST) have made an exciting discovery about the early universe. They found dozens of small galaxies that played a huge role in transforming our cosmos from a dark, foggy place into the bright, clear universe we see today.
The James Webb Space Telescope has recently identified evidence of the presence of carbon-based molecules in the atmosphere of an alleged ocean world called K2-18 b. The team responsible for this observation also refers to the possible detection of a by-product of life on Earth. A planet that intrigues researched using the James Webb Telescope [...]
The James Webb telescope detected 83 mini-galaxies that may have triggered reionization, a major turning point in the evolution of the Universe.
