Because they run out of the resources they use which consist of gases. It eventually 'dies' just like you would if you didnt eat food for a long period of time.
This results in the star dying/exploding causing a supernova explosion
they are called super novas
Most do not. Stars about 10 times more massive than the sun or larger will explode. Smaller stars shed their outer layers gradually.
When smaller stars explode (like our Sun), they leave a nebula cloud by releasing their gas and they become a small but dense white dwarf star.When big stars explode (like Betelgeuse), they have a massive explosion called a supernova and the core of the star turns into a black hole or a pulsar.
They explode with nuclear explosions.
A Galaxy could not explode. An individual star can, and does, but a Galaxy consists of billions of stars quite widely separated.
Novas
No. Only the most massive stars explode.
Depends on which 5 stars
stars explode
Some stars do. They can be nova or supernova stars, depending on the scale of the explosion.
Some stars explode in a supernova.

well it depends on the star. not all stars explode. small to medium sized stars just go into a planetary nebula after they swell up to a red giant then the bigger stars do explode, they have a super nova after the swell up into a super giant. but dont worry i star will not explode... its a really small star. --- nichole brooks :)
Massive stars are most likely to explode faster than smaller stars.
Yes. It must, all stars explode at one point of time.
