How are stars born?

In space clouds of gas and dust get pulled together by gravity until they get formed into spinning clumps. The next thing that happens is it starts to cave in on itself causing it to heat up. Once it heats up to a few million degrees, nuclear fusion fuses it together and.. BAM! The star is born.

After the time is up some stars become supernovae. However not all stars die in violent explosions. Some stars gently become planetary nebulae, which is a nebula that is ring shaped and made by an old star shelled with gas.
