Could stars be dead?
The stars we see are so far away, that their light can take hundreds or thousands of years to reach us. So long after the light we saw left the star, but before the light arrived here, the star may have blown up. We would not know for a long time after that. So many of the stars that we do see may be long dead.
When small stars get old they become?
When small stars get old, they become white dwarfs. This happens after they have exhausted their nuclear fuel and shed their outer layers. Eventually, the core collapses to form a dense, Earth-sized remnant known as a white dwarf.
Why do stars stop shining?
Stars stop shining when they exhaust their nuclear fuel in their cores. As the fuel runs out, the star's core collapses under its own gravity and the outer layers are expelled in a supernova explosion. The remaining core might become a dense object like a white dwarf, neutron star, or black hole, and it will no longer shine brightly.
Why is the sun or the star eventually die?
A star eventually uses up all of it's hydrogen in nuclear fusion. They fusion of hydrogen into helium is what makes the star glow bright and hot. When all the helium is fused, the star collapses inward on itself, and becomes a small "white dwarf" star, essentially a pile of "stellar embers". That's the end of a star's life.
How do stars regenerate?
Sea Stars can grow back legs or arms if one gets cut off.
Why do sun like stars turn into white dwarfs?
It is because it collapses after it has run out of "fuel".
What happens to a star when it has used up all its fuel?
It collapses.
Where do neutron stars form?
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.

What happens when fuel is burnt in a gas boiler working normally?
the fuel goes 50x more hotter than itself and changes it's colour and becomes poison-us

After what evolutionary stage does a star become a white dwarf?
A star becomes a white dwarf after it exhausts its fuel and undergoes fusion reactions that lead to its outer layers being expelled as a planetary nebula. The remaining core collapses and becomes a dense, Earth-sized white dwarf composed mostly of electron-degenerate matter.
How come some stars die in supernovas?
Not all do, only ones that are massive enough that when Helium and Hydrogen stop burning are unable to maintain hydrostatic equilibrium and the matter collapses on itself. Some obtain this matter by pulling it off a companion or merging with another star, some are just so large that after the fuel is up it cannot support its own weight.
What force causes extremely high mass stars to turn into black holes instead of nuetron stars?
Black holes are formed by super massive stars when they collapse. Less massive stars will form neutron stars. Therefore, the original size and mass of the star will determine if a black hole will be created when the star collapses.
