WebQuestion Date: 1999-06-03. Answer 1: Stars are formed from large clouds of gas. The gas, which might be the wisps of older stars which have exploded, or simply left from the Big Bang, is very cold and the cloud begins large but not at all dense. Gravity, which causes all the atoms of the gas to pull each other together, makes the cloud contract. WebStars are made mostly of hydrogen and helium, which are packed so densely in a star that in the star’s center the pressure is great enough to initiate nuclear fusion reactions.

Modern estimates from radioactive dating give an age of the Earth of 4.6 Billion years. The Sun can potentially shine for about twice that, averting the age crisis. fl studio church organ

"WebIf the star isn't large enough, nuclear fusion may stop, before the core of the star is fused to iron, since very high temperature (more than 2 billion Kelvin) and pressure are needed to fuse silicon to iron. This way the core may collapse earlier. The collapse releases energy responsible for much of the luminosity of the supernova. " - How does nuclear fusion cause a star to shine
