How do stars die? (Black holes, neutron stars, red giants, supernovae)?

Stars are like giant hot balloons that eventually pop, but not all stars pop the same way.

When a star is young and healthy, it burns fuel, just like how you burn food to have energy. But when it runs out of fuel, it starts to change shape, like when your balloon loses air and gets bigger or smaller.

What happens after a star runs out of fuel?

If the star was big, it might turn into a red giant, imagine your balloon getting so full that it stretches out and becomes red and glowing. Then, if it’s really big, it might explode in a supernova, like when a balloon pops with a huge bang.

If it's not too big, it might shrink down to a neutron star, think of it like a super-dense marble that still glows.

And sometimes, if the star was super big, it might collapse into a black hole, like when all your toys fall into a bottomless pit and you can’t see them anymore. Stars are like giant hot balloons that eventually pop, but not all stars pop the same way.
