Cosmic element distribution refers to the abundance and spatial arrangement of chemical elements in the universe, shaped by processes such as nucleosynthesis in stars and supernovae. Understanding this distribution helps scientists trace the evolution of the cosmos from the Big Bang to the present, revealing insights into star formation, galaxy evolution, and the origin of life-essential elements.

Nucleosynthesis in stars

Supernovae are powerful and luminous stellar explosions that occur at the end of a star's life cycle, either through the collapse of a massive star or the accumulation of matter on a white dwarf. These events are crucial for the creation and distribution of heavy elements in the universe, influencing galactic evolution and serving as important tools for measuring cosmic distances.

Evolution of the cosmos

The Big Bang theory is the prevailing cosmological model explaining the observable universe's origin from an extremely hot and dense singularity approximately 13.8 billion years ago. It describes the universe's expansion and the formation of fundamental particles, leading to the development of galaxies, stars, and planets over time.

Big Bang

Star formation is a complex process that occurs in molecular clouds, where regions of high density and low temperature allow gravity to overcome pressure, leading to the collapse of gas and dust into protostars. This process is influenced by various factors including turbulence, magnetic fields, and feedback from nearby stars, ultimately determining the mass and evolution of the newly formed star.

Galaxy evolution is the process by which galaxies form and develop over billions of years, influenced by various astrophysical phenomena such as mergers, star formation, and feedback from active galactic nuclei. Understanding galaxy evolution helps us trace the history of the universe and the formation of cosmic structures from the Big Bang to the present day.
