Life Cycle of a Star From Molecular Clouds to Supernova

Stars are born within dense regions of gas and dust called molecular clouds or nebulae. These clouds exist in various parts of galaxies where gas and dust are concentrated. These clouds collapse under gravity, forming a protostar - a hot, dense core that will eventually become a star. • During a star's life cycle, hydrogen undergoes nuclear fusion into helium in its core. This remarkable fusion process releases a tremendous amount of energy, which ultimately fuels the star, giving it its luminosity. • Massive stars undergo a more dramatic evolution. They fuse heavier elements in their cores, progressing from helium to carbon, oxygen, and eventually iron. • Iron fusion in a massive star's core consumes energy instead of releasing it. This depletion of energy leads to a catastrophic collapse, resulting in a supernova, an incredibly powerful explosion. • Depending on the mass of the collapsing star - a supernova can leave behind a neutron star or a black hole. • • _________ • Source of visuals: • NASA • NATIONAL GEOGRAPHIC • ESA • _________ • #space #nasa #spacex #astro #cosmos #esa #hubble #wormhole #astronomy #physics #simulation #astrophysics #halloween #cosmology #space #science #sciencememes #future #multiverse #spacelovers #universe #videogames #nasa #game #earth #physics #physicsmemes #cosmos #stars #star #technology #spacelover #astrophile #blackhole #solarsystem #sun #astronomy #size #simulation #universe #galaxy #milkyway #phoenix #physics #science #cosmos #star #earth #moon #stellar #evolution
