"WebThe changes that occur in a star over time and the final stage of its life depend on a star's size . Nuclear reactions at the centre (or core) of a star provides energy which makes it shine brightly. This stage is called the ' main sequence '. The exact lifetime of a star depends very much on its size. Very massive stars use up their fuel quickly. " - Describe the formation of stars

WebFeb 23, 2024 · In the early universe, stars were formed primarily from hydrogen and helium. Heavier elements have and are still being created through cosmic ray interactions, fusion in the interiors of stars, stellar explosions and collisions, and other processes. That new material is eventually recycled into subsequent generations of stars and planets. WebStars form in huge clouds of gas and dust called nebulae. These areas of space are sometimes known as 'stellar nurseries' or 'star forming regions'. The gravity of the gas and dust in the clouds pulls everything inwards. The clouds slowly collapse onto a number of points (or cores). Deep in the centre of these cores, there is lots of dense ...
