A star is born within a vast, cold cloud of gas and dust in space called a nebula. The process of star formation begins when gravitational forces within the nebula cause the cloud to contract and collapse under its own weight.
Here are the main steps in the birth of a star:
1.
How are stars born and how do they die
Gravitational collapse: As the nebula collapses, the gas and dust particles within it start to clump together, forming a dense core. This process is driven by gravity and may be triggered by external factors, such as shockwaves from a nearby supernova explosion or the collision of two massive molecular clouds.
2.
Formation of a protostar: As the core of the collapsing nebula continues to compress, it heats up and forms a protostar. A protostar is an early stage in stellar evolution where the core hasn't yet ignited nuclear fusion.
During this phase, the protostar is primarily heated by gravitational energy, and it emits infrared radiation.
3. Accretion and rotation: Surrounding the protostar is a rotating disk of gas and dust called
