Nuebla
The nebula is a giant cloud full of dust and gas, mostly hydrogen and helium. Though the dust and gas are normally spread out very well, they tend to slowly come together and form big clumps. As the clumps tend to get bigger and bigger, their gravity becomes stronger and stronger.
Although some of the nobles have more than others, some from the dust and gas cloud are thrown from the explosion and possibly a dying star.
A nebula is known to be called a Helix Nebula. It's the meaning of a dying star. It's around 700 light years from the earth. If you could travel at light speed it would take you 700 days but if you traveled at normal speed it would take much longer than the light speed.

Average stars are as well known as the intermediate - mass star or white dwarfs . The stars now have more lifetime between 50 million and 20 billion years. The Average stars become white dwarfs. Average stars are around the size of dead stars despite containing the mass of the star. The bigger the core the denser the white dwarf is the better the form it will be. The white dwarf is small they fade into oblivion as they gradually cool down.
The more massive the core the denser the white dwarf is the better the form if it will be. The white dwarf is small they fade into oblivion as they gradually cool down.

Massive Stars are known as hyper giants.They are almost 100 or more times more massive than the sun. The star itself has a surface temperature of more than 30,000K. An average star it is made up of hydrogen fusion in the car and is followed by several other fusion reactions involving the heavier elements.

A red giant is something that forms when a star or any star ends up running out of hydrogen fuel and begins the process of dying. All though a red giant can take millions of years to form. When more of the hydrogen runs out and the red giant cant take it anymore. There's something called a red supergiant that ends up taking over instead

A red giant is able to be 20 and 100 times the size of the sun though only they can contain 0.25 to 8 times the mass of the sun. They are as bright as stars. The surface temperature of a red giant is less than 4,000 -5,000k.
As time passes through the outer lars tend to expand, gravity causes its core to shrink and contract. You may think this is weird and that this can not be true but Red Giants can swallow up planets as they expand

Planetary Nuebla
Planetary star is a phase of the low mass star. During the phase of the star it starts shred the outer layers which ends expanding the most outer layer and it tends to get big and bigger. When it turns into a low mass star that will eventually turn into a red giant phase. Since the star keeps changing phases.

A plaentary can last up to ten thousands years. All though our sun is low which can reproduce nueblas in abotu 5,000 million years.
Supernova
Supernovae are actually explosions in the sky. When a supernova explodes one will be brighter than the other. Supernovae can be caused by pressure dropping.This is a quote from the website that says "Once a century."That's when they may see a supernova.

White Dwarf
"A white dwarf is the stellar core left behind after a dying star has exhausted its nuclear fuel and expelled its outer layers to form a planetary nebula." Which means a white dwarf is a dying star.

Nuetron Star
A neutron star is the collapsed core of a massive supergiant star, "Matter falling onto the surface of a neutron star would be accelerated to tremendous speed by the star's gravity." All though nuetron atars are mad up of 95% of neitrins.
