Massive star formation

Massive star formation begins within dense, cold clouds of gas and dust in space. Gravity causes parts of these clouds to clump together, forming a core that heats up as it collapses. Over time, the core gathers more material, and nuclear fusion eventually ignites in the center, creating a new star. Because these stars are large, they form in regions with abundant gas, and their intense radiation and winds influence their surroundings. This process takes millions of years and often occurs in star clusters, shaping the structure and evolution of galaxies.
