JWST and Chandra push back the cosmic timetable — MoM‑z14, an early cluster and a Helix Nebula close‑up
New observations from NASA’s James Webb Space Telescope, supported by Chandra X‑ray data, show structure forming far sooner than expected: JWST confirms the most distant galaxy yet (MoM‑z14 at ~280 million years after the Big Bang) and detects a galaxy cluster assembling unusually early, while also returning a detailed Helix Nebula portrait.
