NASA’s James Webb Space Telescope has made a groundbreaking discovery, spotting the earliest and most distant galaxy known to researchers. The galaxy, identified as JADES-GS-z14-0, was observed just 290 million years after the Big Bang, providing unique insight into the formation of galaxies in the early universe.
Scientists studying “Cosmic Dawn” used the telescope to capture an image of this distant galaxy, revealing a redshift that indicated its remarkable distance from Earth. The galaxy’s size, over 1,600 light-years across, suggests it is composed of young stars rather than a black hole.
The presence of oxygen in the galaxy’s emissions was a surprising discovery, indicating the existence of multiple generations of very massive stars. This finding has opened up new possibilities for understanding the evolution of galaxies and stars in the early universe.
With the potential for more luminous galaxies to be detected, researchers are excited about the prospects of further unveiling the mysteries of the Cosmic Dawn and gaining valuable insights into the foundation of our universe.
