Question: how are stars created ?

Alexander Finch answered on 17 Dec 2015:

Stars are created from vast clouds of gas in space that, under their own gravity, come together.Much of this gas is light hydrogen and Helium that forms the star. When there’s enough gas that’s clumped togther, the centre stars getting hot – so hot that is actually starts “burning” in a nuclear fireball! When this happens, the gas superheats and gives of lots of light and heat – et volia, we have a star!

The planets form around the star from roughly the same material around the same time!
