Not only living beings, but inanimate objects like stars too.</p> <p><strong>The birth of a star</strong></p> <p>The universe has massive clouds of hydrogen floating around. Sometimes, these clouds come together and form very dense and huge balls of hydrogen gas. As the clouds come close, their temperature increases. This is called a proto-star (original star).</p> <p>The increase in temperature triggers off nuclear reactions at the core of the star. Nuclear reactions inside the star occur when the nucleus of two hydrogen atoms fuse to produce a helium atom. This reaction which is actually the same as that inside a hydrogen bomb, release huge amounts of heat and light. This is what makes a star glow.</p>
