No and no. And I do not care about getting the ten points to give some long-winded explanation which you could easily search for on Google.

Start with "stellar evolution"...your question demonstrates that you know very little about the subject. I don't see why you expect people to put forth a great effort to educate you when you put no effort into it yourself.

The Sun is to small to go supernova only stars many times more massive than the sun are able to go supernova. The subject about the sun melting into its core is the worst thing I have heard (but don't feel bad, I will describe what will happen below). When the sun runs out of hydrogen it will have to find other material to use up and after that it will have to find something else, because of that the sun will expand roughly 100 times its original size. By then it will be a red giant and Earth won't exist. It will be dust and echo's in space. It will start to collapse and compress which the it will puff off its outer layers just like a smoker puffing out a smoke ring. After it is done blowing off it outer layers the core is all that's left. It will become a(n) object about the size of Earth and is called a white dwarf and will no longer produce heat. Eventually the white dwarf will fade into a dead star. Look on google images or whatever for pictures of White Dwarfs and Dead Stars. The Dead Star is the final phase of its life, it will be a nebula. Hope this is good enough to answer your question.

No, the Sun won't go supernova --- it's not massive enough, neither is it a member of a binary system, the two routes to becoming a supernova. Instead, it will swell up and become a red giant first, and after several more twists and turns, end up as a white dwarf of something like 0.5 - 0.6 solar masses. It will not have "melted to its [degenerate] core," but will rather have lost mass in both its red giant and planetary nebula phases.

It used to be thought that because the Sun will swell to 150 - 200 solar radii as a red giant, Mercury and Venus would be vaporised or burnt up during the expansion, and that a variant of that fate would await the Earth. According to that earlier view, the Earth would either be vaporised or burnt up, if not completely, at least to quite a crisp or boil, with a minimum surface temperature close to that of the boiling point of lead.

However, that was before it was really understood how ubiquitous mass loss is on the upper reaches of the red giant branch (RGB). Now that the fact of such generally substantial mass loss has been accepted, the situation is brighter for the Earth's future (in the sense that the sky will be LESS bright)!

Because of the reduction in the Sun's mass, but the Earth nevertheless conserving its angular momentum around that decreasing central mass, its orbit will become LARGER. It will actually BACK OFF from the Sun, and should survive the Sun's passage along the RGB!

It will still be tough for Venus, though. It's only ~ 40 % of the Earth's distance away from the Sun, and the Sun's evolutionary expansion will itself overtake Venus's expanded orbit. So Venus will still be consumed.

So there you have it. Farewell Mercury and Venus. For Earth, there will be "a hot time in the old town tonight," but not necessarily completely catastrophic, while the remaining planets will sail blitherly on about the dying and fading remnant of the present Sun.

Live long and prosper.

LATER POSTSCRIPT: The estimate someone else gave for the Sun's present central temperature of "about 45 million degrees (a student once asked me if that was Fahrenheit or Celsius, and my response was, at that temperature, who cares?" [sic] was WAY OFF.

According to the best current models, the Sun's central temperature is approximately 15.5 million degrees Kelvin, or about 28 million degrees Fahrenheit. That's a goood deal les than either 45 x10^6 F or C.

There are several types of supernovae and at least two possible routes to their formation. A massive star may cease to generate energy from the nuclear fusion of atoms in its core, and collapse under the force of its own gravity to form a neutron star or black hole. Alternatively, a white dwarf star may accumulate material from a companion star (either through accretion or a collision) until it nears the Chandrasekhar limit of roughly 1.4 times the mass of the Sun, then undergoes runaway nuclear fusion in its interior, completely disrupting it. This second type of supernova is distinct from a surface thermonuclear explosion on a white dwarf, which is called a nova. Solitary stars with a mass below approximately 8 solar masses, such as the Sun itself, will evolve into white dwarfs without ever becoming supernovae., You don't have to worry, it will take many years to happen and we won't be around

No to both of them. The sun shares on phase similar to that of a blue giant: the growing phase. It will grow into a red giant, and will be big enough to swallow mercury and venus (Earth, if not engulped, will literally be skimming the edge of the sun), but then it will shrink back down again and eventually become a white dwarf, no explosions.

The other question is just common knowledge. the sun is hotter than it will ever become in the feuture, which means that it will never melt itself. It will shrink down to the core, but thats about it.

The sun does not have the mass to go super nova. Please help me others but I think a star needs 3.4 to 8 solar masses to go super nova. Below that amount, up to about our sun it will expand as a nebula. As the last of the hydrogen changes to helium the internal gravity of the sun will not be enough to hold onto its mass and it will expand outside the current distance from the earth to the sun (one A.U) If it does truly go to become a planetary nebula then the gas can expand a few light years.
My question is will our sun become a neutron star when it uses up all it's fuel?

The sun's too small to go supernova. It'll become a red giant before collapsing into a dwarf star.

it won't go supernova, it will die as a white dwarf
