Second-generation stars are stars that formed from the remnants of first-generation stars, which were primarily composed of hydrogen and helium. These stars typically contain heavier elements produced through nuclear fusion in their predecessors, providing insights into the chemical evolution of the universe.
Cosmic archaeology is a field of study that investigates the history and evolution of the universe by analyzing ancient celestial objects. This approach helps astronomers understand the formation of galaxies, stars, and the distribution of elements in the cosmos.
