James Webb Space Telescope’s Ultra Deep Field image reveals thousands of distant galaxies in infrared, helping scientists study the universe’s earliest stars and galaxies.

The image reveals over 2,500 galaxies, many of which are seen as they were during the first billion years of cosmic history.

Over 20 years ago, the Hubble Space Telescope looked at a little patch of sky for days, with this methodical approach ...

Webb has provided an unprecedentedly rich and detailed glimpse into the distant Universe, capturing thousands of galaxies, some from the earliest epochs following the Big Bang.

The new image covers about a quarter of the original UDF but still contains ~2,500 galaxies, many too faint for Hubble. In parallel, the JADES team used Webb's NIRSpec spectrograph on 253 very faint ...
