When a large cloud of dust and gas begins to collapse due to gravity, it can undergo a process called protostar formation. As the cloud collapses, it heats up and starts spinning, eventually forming a dense core at its center. This core will continue to accumulate material and eventually become hot and dense enough to initiate nuclear fusion, becoming a star.
if they are massive enough and have sufficient gravitational force to overcome pressure forces and begin the process of nuclear fusion, which powers stars. This collapse is triggered by disturbances such as shock waves from supernovae or gravitational interactions with other clouds.
Stars begin their lives as clouds of gas and dust called nebulae. Within these nebulae, gravity causes the gas and dust to collapse and heat up, eventually leading to the ignition of nuclear fusion in the core, which marks the birth of a star.
Glowing cloud sections that will eventually become stars are protostars. These protostars are clouds of interstellar gas and dust, which gradually collapse causing a hot dense core to form and evolve into a star.
A nebula collapses primarily due to gravitational forces overcoming internal pressures. As the gas and dust within the nebula begin to clump together under their own gravity, the density increases, leading to a rise in temperature and pressure at the core. This process can be triggered by external events, such as shock waves from nearby supernovae or the collision of molecular clouds. Eventually, the collapse can lead to the formation of stars and planetary systems.
Nebulae are massive collections of gas and dust that usually are very cool around 5-30 kelvin. These nebulae are the remains of dead stars that have long died and have had enough time to cool themselves from the original energy release of the nova or supernova that created them. As the nebula cools the particles begin to slow down and once cool enough gravity will begin to collapse the nebulae and form what is known as a protostar. This is the birth of stars, and is essential for star formation.
They begin to fall as rain.

Stars start out as clouds of gas and dust in space. Through the process of gravitational collapse, these clouds condense and heat up, eventually forming a protostar. As the protostar continues to accumulate mass, nuclear fusion reactions begin in its core, leading to the birth of a star.
All-stars begin their lives as a part of a molecular cloud in space. These clouds contain gas and dust that eventually collapse and form stars through the process of nuclear fusion. The intense pressure and heat at the core of the collapsing cloud triggers the fusion of hydrogen atoms into helium, leading to the birth of a new star.
Stars usually begin their lives in stellar nurseries: (relatively) dense clouds of interstellar gases. Critical densities may be achieved when nearby stars go nova, at which time pockets in the nebula collapse under their own weight to form a protostar. If the mass of the protostar is sufficient, further gravitational collapse will cause the temperature and pressure in the core to rise to the point where hydrogen starts to fuse. At that point, a star is born.
Stars begin their lives as clouds of gas and space dust.
rain: the clouds collect eough water from the ocean to the clouds and the clouds get too heavy and have to fall down. hail: the water from the clouds get frozen and turn into snow
When clouds increase, whole areas of stars may be hidden by clouds with groups of stars, still in the clear sky, seem to huddle together. The clouds are increasing, so the chance of rain is increasing too.
Stars form in space when giant gas clouds start to clump together and collapse in upon themselves. This clumping is often caused by energy waves from nearby exploding supernova (dying stars). As they collapse, the molecules that form the clouds compress in upon each other to form helium and hydrogen. Once gravity pushes them together strongly enough, nuclear fission will begin to occur in the core of the star. This process will continue throughout the life of the star, until all of the fuel is used up.
Glowing cloud sections that will eventually become stars are protostars. These protostars are clouds of interstellar gas and dust, which gradually collapse causing a hot dense core to form and evolve into a star.
Clouds of gas will collapse, under certain circumstances, due to their own gravity. These will eventually become stars. This process is described in more detail in the Wikipedia article on "Protostars".
