Nebulae are star factories because they are vast clouds of dust and gas in space that can collapse under their own gravitational forces, leading to the formation of new stars. Within nebulae, gas and dust particles come together to form protostars, which eventually evolve into full-fledged stars through the process of nuclear fusion. This ongoing cycle of star formation within nebulae replenishes galaxies with new stars and contributes to the overall creation and evolution of stellar systems.
