ScienceSpace ExplorationExplore the fascinating journey of stars, from their formation to their eventual demise. Learn about the creation of new elements, the evolution of white dwarfs, and the ultimate fate of black dwarfs.
The Birth and Evolution of Stars
⭐The universe began as a dark and warm place filled with hydrogen and helium gas.
⭐Stars formed and released new elements, cycling matter and creating new generations of stars.
⭐Not all gas is returned, leading to the eventual end of the universe.
The Journey of White Dwarfs and Black Dwarfs
💫White dwarfs are the third densest objects in the universe, after neutron stars and black holes.
💫White dwarfs are slowly losing their heat and will eventually die, taking at least 10 trillion years.
💫Over trillions of years, every object in every galaxy will eventually turn into black dwarfs.
