Stellar birth - stellar genesis - stellar formation - star birth - star genesis

Star formation is the astrophysical process by which dense regions within molecular clouds collapse under their own gravity to give birth to new stars. It typically begins in cold, dark nebulae where gas and dust accumulate and fragment into cores. As these cores contract, they heat up, forming protostars surrounded by rotating disks of material. Over time, nuclear fusion ignites in the core, and a stable main-sequence star emerges. Star formation influences the structure and evolution of galaxies, drives chemical enrichment of the interstellar medium, and often occurs in clusters, shaped by turbulence, magnetic fields, and stellar feedback.
