After the Sun becomes the Red Giant, could Pluto and its cousins in the Kuiper Belt, as well as Triton, moon of Neptune, be the most valuable real estate in the Solar System?

What have you ever thought about it?

Not neither Today nor ever, even though with these worlds they maintain abundant water ice and complex organic materials, were evaporated, their rocks and the approach, became the next meal of the sun, in its barbecue.

Initially, some of them could even some time ago keep oceans under their icy surfaces, or at least they could in the distant past.

Then, when the surface temperatures of these dwarf planets tend to be hundreds of degrees below zero, but when Earth is grey, Pluto's temperatures will be similar to our planet's current averages.

After the Earth was baked, then we have on the solar menu, in its hunger for expansion, other planets, which however icy they were initially Pluto was initially pleasant and filled with the same kinds of complex organic compounds that existed.

Even under human thoughts when they initially started colonization in their attempt to live, that's when life first evolved on our planet, in addition to having an atmosphere, a thick atmosphere and a surface of liquid water.

Where collectively the worlds in this new habitable zone will have three times as much surface area as all the first four planets in the solar system combined.

When a massive star reaches the end of its life, it can cause an explosion so luminous and so powerful that it is capable of eclipsing entire galaxies.

It was next, how much more energy to release than the Sun will be able to emit throughout its lifetime, where then these explosions are known as supernovae and are among the most powerful to happen in space.

When sunlight arrived in various parts of the universe in which I must say that light years still saw a genocidal spectacle of mass death, both of the sun and of the life of any nearby planet, in what was left over when they had not yet been baked, they died at the time, there was no powder left.

Those who survived died frozen, as they took refuge underground, in which the explosion of sunlight, did not last for seconds or minutes, but hundreds of thousands of years of stellar roasts.

When they showed and saw the explosion of a supernova in a distant galaxy, when tree trunk rings might indicate the effects caused by supernovae, if they still exist, they evaporated.

This is one of the largest supernova remnants ever detected in the Milky Way, slingshot remnants of what was once a tree trunk frozen by the thunderous explosion of a sun, what was left was released, what was left evaporated.

The universe is home to several remnants of ancient supernovae, which are what's left after star explosions that reached the end of their lives. Furthermore, if we consider the Milky Way and its (almost) 200 billion stars, it is possible that there is a supernova occurring, on average, every 50 years, when they see their luminous remnants.

In which, by the way, supernovas are also an excellent example of how the demise of stars is essential to start other processes, since they are the ones that spread the heavy elements produced in their nuclei through the interstellar medium.

So when their elements reorganize to form new stars, planets and everything else that exists in our neighborhood, which that was including us, they become nothing less than stardust.

Between a black hole and a supernova occurs when stars explode at the end of their lives, that said, although it is practically impossible to know precisely which star was the first of its kind to explode, there are records of the oldest supernova ever observed.

Taking place during the year 2185 when some refugees from Earth, in which they looked at the night sky and observed that there was something there that looked like a new star.

When it glowed and didn't seem to move, that is, it couldn't be a comet, where the point of light continued in the sky for about eight months, until it just disappeared.

Although both novae and supernovae are sudden, bright explosions that spew gases at very high temperatures, there are important differences, as supernovae are much more intense and signal that the very massive star has reached the end of its life, when the sun came to to become a badass and brilliant supernova.

What was all this about? To understand what supernovas are, we need to understand, first, the life cycle of stars, in which they are all born from clouds of gas and dust, but what determines the cycle and its end is the your mass.

This is why less massive stars can "die" as white dwarfs, while those that are at least eight times as massive as the Sun can become supernovae or black holes, as in the case of much more massive stars.

When the Earth's Sun, for example, had a quieter fate than other more massive stars, knowing how it's not massive enough to explode into a supernova when its fuel runs out.

Where the layers of the Sun will expand until it becomes a red giant, but that's not exactly good news for Earth, as our planet and the rest of the inner Solar System will likely be swallowed up and consequently destroyed in this stage.

Afterwards, the star will be unstable and its outer layers will dissipate, forming a planetary nebula, and in the end, there will only be a white dwarf, formed by the Sun's core.

In the case of more massive stars, the scenario is a little different.

When they produce huge amounts of energy with nuclear fusion, and their center heats up and generates pressure, which is essential to prevent their own structure from collapsing, because, while gravity tries to compress it as much as possible, the Pressure created by core reactions resists the gravitational pull.
