Everything follows the same cycle thought its existences. A cycle of birth, living, and death, of a being. And though some things may not be connected, or even four light years away, like stars and humans. They still are very much the identical. Humans are born, while stars are created. Then, a Humans work through their lives: school, to a job, or work, or on personal work . On the other hand, a star's work is just being. But, through every life cycle comes death. While humans and stars die for differential reason and ways, humans and stars follow the same pattern, but just with different details. All things have a life cycle of creation, life, and dying, including the stars.
A star's birth starts with a interstellar cloud. A interstellar cloud, or a interstellar medium, is a cloud made of hydrogen gas and dust. Also, the interstellar cloud is a filled space between the other stars, that has a rattling low density (Interstellar Medium). A star forms from a interstellar cloud by combining with other atoms. With the temperature being, nothing to just above zero degrees, the atoms of the gas' start to sick together. Then the star forms in a molecular cloud. A molecular cloud, is just a thick compact of interstellar gas and dust.
Then the interstellar collapse under the gravitational force of a supernova. A supernova, as Nasa explains is “A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass” (NASA. NASA). The collapsing of the interstellar clouds then begins so spin into a flattened disk like form. The disk becomes dense, after mixing in the center, and the temperature begins to rise. As the mixing and spinning continue and more material blends to form a prot...

But this does not justify it. Whether there is a star after the other, the assumption of uniform distribution (at that time there was no reason to think of a more privileged, more full of stars elsewhere) allows the existence of stars "next". This formal language, the stars are "dense" in the celestial sphere.

Stars are born and reborn from an explosion of a previous star. The particles and helium are brought together the same way the last star was born. Throughout the life of a star, it manages to avoid collapsing. The gravitational pull from the core of the star has to equal the gravitational pull of the gasses, which form a type of orbit. When this equality is broken, the star can go into several different stages. Some stars that are at least thirty times larger than our sun can form black holes and other kinds of stars.
Solar nebula is a rotating flattened disk of gas and dust in which the outer part of the disk became planets while the center bulge part became the sun. Its inner part is hot, which is heated by a young sun and due to the impact of the gas falling on the disk during its collapse. However, the outer part is cold and far below the freezing point of water. In the solar nebula, the process of condensation occurs after enough cooling of solar nebula and results in the formation into a disk. Condensation is a process of cooling the gas and its molecules stick together to form liquid or solid particles. Therefore, condensation is the change from gas to liquid. In this process, the gas must cool below a critical temperature. Accretion is the process in which the tiny condensed particles from the nebula begin to stick together to form bigger pieces. Solar nebular theory explains the formation of the solar system. In the solar nebula, tiny grains stuck together and created bigger grains that grew into clumps, possibly held together by electrical forces similar to those that make lint stick to your clothes. Subsequent collisions, if not too violent, allowed these smaller particles to grow into objects ranging in size from millimeters to kilometers. These larger objects are called planetesimals. As planetesimals moved within the disk and collide with one another, planets formed. Because astronomers have no direct way to observe how the Solar System formed, they rely heavily on computer simulations to study that remote time. Computer simulations try to solve Newton’s laws of motion for the complex mix of dust and gas that we believe made up the solar nebula. Merging of the planetesimals increased their mass and thus their gravitational attraction. That, in turn, helped them grow even more massive by drawing planetesimals into clumps or rings around the sun. The process of planets building undergoes consumption of most of the planetesimals. Some survived planetesimals form small moons, asteroids, and comets. The leftover Rocky planetesimals that remained between Jupiter and Mars were stirred by Jupiter’s gravitational force. Therefore, these Rocky planetesimals are unable to assemble into a planet. These planetesimals are known as asteroids. Formation of solar system is explained by solar nebular theory. A rotating flat disk with center bulge is the solar nebula. The outer part of the disk becomes planets and the center bulge becomes the sun.
If the nebula is dense enough, certain regions of it will begin to gravitationally collapse after being disturbed. As it collapses the particles begin to move more rapidly, which on a molecular level is actually heat, and photons are emitted that drive off the remaining dust and gas. Once the cloud has collapsed enough to cause the core temperature to reach ten-million degrees Celsius, nuclear fusion starts in its core and this ball of gas and dust is now a star. It begins its life as a main sequence star and little does it know its entire life has already been predetermined.

The Big Bang, the alpha of existence for the building blocks of stars, happened approximately fourteen billion years ago. The elements produced by the big bang consisted of hydrogen and helium with trace amounts of lithium. Hydrogen and helium are the essential structure which build stars. Within these early stars, heavier elements were slowly formed through a process known as nucleosynthesis. Nucleosythesis is the process of creating new atomic nuclei from pre-existing nucleons. As the stars expel their contents, be it going supernova, solar winds, or solar explosions, these heavier elements along with other “star stuff” are ejected into the interstellar medium where they will later be recycled into another star. This physical process of galactic recycling is how or solar system's mass came to contain 2% of these heavier elements.
Supernovas are extremely powerful explosions of radiation. A supernova can give off as much energy as a Sun can within its whole life. A star will release most of its material when it undergoes this type of explosion. The explosion of a supernova can also help in creating new stars.
...ch one of us has a star that our soul is associated with. Our task as human is to try to live a good live so that when we reincarnate we can return to our associated star. In their own way they both sought to explain the nature of reality and how we could know what is real.

Generally, the universe began as a composition of radiation and subatomic particles, which proceeded with galaxies formation. Galaxies are made up of hydrogen, helium, 100-200 billions of stars, planets and most having a black hole at the center, which attracts everything present in galaxies by force of gravity. Galaxies can be classified as either spiral (Milky Way- galaxy which human kind has been found to exist), elliptical, lenticular and irregular, where the structure is determined by neighboring galaxies with most galaxies are moving away from each other. Classification of galaxies is being conducted by online programs such as Galaxy zoo, using pictures from telescopes and is making significant progress.
