Unveiling the Secrets of Carbon-Rich Grains from Over a Billion Years Ago with the James Webb Space Telescope
In a major breakthrough, scientists have discovered carbon-rich grains that are over a billion years old, which were discovered in the debris of a supernova. These grains are composed of silicon carbide, an extremely hard and heat-resistant material, and are thought to be the oldest solid material ever discovered. This discovery is giving us a better understanding of the evolution of the universe and how stars form and evolve. The discovery of these grains could have a significant impact on our understanding of the chemical evolution of the universe.
