WebOur closest star the sun was formed about 4.5 billion years ago. Stars are created as the nebula slowly contracts under its own gravity caused by gravitational attraction and a clump of matter forms inside the cloud. Gravity continues pulling in more matter and the clump collapses inward. The clump becomes denser and begins to heat up. WebMassive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow …

WebThe life cycle of a star larger than the Sun starts in the same way as a solar mass star. 1. Nebula. All stars form from a giant cloud of hydrogen gas and dust called a nebula. 2. Protostar. The force of gravity within a nebula pulls the particles closer together until it forms a hot ball of gas, known as a protostar. WebStellar Evolution. Just like humans, stars go through a life-cycle from young protostars to elderly white dwarfs. We classify stars according to their colour, which is related to their temperatures. There is also a relationship between the colour of stars and their brightness, which is represented on Hertzsprung-Russell diagrams. thin lizzy vagabonds
