A star is a vast ball of plasma (ionised gas) held together by gravity and undergoing nuclear fusion.
A star is squashing atoms together to make bigger ones - by what is called 'nuclear fusion' - they can do this because they are so heavy and hot. This process gives out lots of energy all the time - which is why they shine. Hope that helps - Jon
