Astronomers have confirmed that a galaxy called MoM-z14 was already shining roughly 280 million years after the Big Bang, making it the most distant spectroscopically verified object ever observed.

One of the James Webb Space Telescope's science goals is to understand how galaxies in the early universe formed and evolved into much larger galaxies like our own Milky Way. This goal requires that ...

Absorption line spectroscopy is a cornerstone technique for probing the gas content, chemical enrichment and kinematics of galaxies in the early universe. By analysing the dark imprints left by ...

When astronomers turned the James Webb Space Telescope onto a tiny red speck of ancient light — a source that existed just 1.8 billion years after the Big Bang — they didn’t expect what came back: ...
