JWST Unveils Secrets of Teenage Galaxies #sciencetime #universe #spacescience

Astrophysicists, using data from the James Webb Space Telescope, have uncovered surprising elements in distant "teenage" galaxies, which formed just 2-3 billion years after the Big Bang. The Chemical Evolution Constrained using Ionized Lines in Interstellar Aurorae Survey revealed these galaxies are hotter than expected and contain unexpected heavy elements, including nickel. By combining light wavelengths from 23 galaxies, researchers created a composite image, revealing a unique chemical composition and high temperatures. This discovery of nickel, a heavy element not commonly observed even in older galaxies, suggests a distinct chemical makeup in these early universe galaxies, potentially linked to their higher temperatures.
