Uranium

Uranium is a relatively abundant heavy element in the universe and is widely distributed within the Earth's crust. As a radioactive and fissile material, uranium plays a crucial role in the energy generation of stars, particularly in their late stages when heavier elements are synthesized through nucleosynthesis. Uranium's decay chain involves the production of elements such as thorium, radium, and lead, influencing the heat generation and internal processes of planets, contributing to their geothermal activity. While direct observations of uranium in astronomical contexts are challenging due to its relatively low abundance in stars and cosmic environments, it has been detected in stellar spectra, offering insights into the age of the celestial object.
