Galaxies die earlier than expected: Webb sees signs of halted star formation 700 million years after Big Bang

Galaxies die earlier than expected

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery deepens the tension between theoretical models of cosmic evolution and actual observations. Among hundreds of spectra obtained with the Webb program RUBIES, the team has found a record-breaking galaxy tha…

A small light signal dating back 300 million years after the Big Bang was detected by the James Webb space telescope and corresponds to the youngest trace of the so-called "reionization" era. Much earlier than previously predicted.

Galaxies die earlier than expected: Webb sees signs of halted star formation 700 million years after Big Bang

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models.

An international team led by the University of Geneva shows that red and extinct galaxies were present only 700 million years after the Big Bang. This tends to indicate that the cessation of star formation occurs earlier than scientists thought.
