Question

Where do all stars begin their evolution

Answer 1

All stars begin their evolution in large clouds of gas and dust called nebulae. These nebulae can be found within galaxies, including our own Milky Way galaxy. The gas and dust within these nebulae slowly start to collapse due to gravitational forces, leading to the formation of a protostar. As the protostar continues to collapse, its core becomes hotter and denser, eventually reaching a point where nuclear fusion reactions begin and a star is born.
