The observations have provided new insights into the presence of heavy elements in the earliest stages of galaxy formation.
Stars generate and synthesize elements in their core through nuclear fusion. Shortly after the Big Bang, hydrogen and helium were the only light elements present were hydrogen and helium, with traces of other elements in the early universe.
As a result, all of the heavier elements, such as carbon, oxygen, and iron, were produced later by stars.Scientists have long postulated that the early universe consisted of these lighter elements, but it wasn't easy to ascertain. However, with the arrival of Webb, scientists can peek back into the. This high-tech space observatory was explicitly built to examine the universe in infrared wavelengths, allowing it to see further into space and time.
