Webb Breaks the Cosmic Distance Record With MoM-z14, Seen Just 280 Million Years After the Big Bang

NASA’s James Webb Space Telescope has identified MoM-z14, the most distant galaxy yet confirmed, seen as it was 280 million years after the Big Bang. The agencies measured a redshift of 14.44, placing the galaxy at the edge of current observational limits. Researchers say MoM-z14 is part of a surprisingly bright group of early galaxies, challenging existing models of the universe’s first billion years.

New James Webb dark matter map exposes the universe’s hidden “cosmic web” in record detail

Scientists using NASA’s James Webb Space Telescope have produced the most detailed dark matter map of the COSMOS field, covering an area 2.5 times the size of the full Moon. The map, created through weak gravitational lensing, reveals the distribution of unseen mass by analyzing shape distortions in nearly 800,000 galaxies. Researchers say the data is twice as sharp as previous maps.
