Good Example Of Essay On The Explanation Of Stellar Evolution

Introduction

Have you ever critically thought out some of the processes that occur in nature? Some are exquisite yet not many have seen them. Planetary Nebulae are one of such processes. Scientists liken it to a butterfly emerging from its chrysalis. It is easy to imagine this, but it would also be educative to find out what the process entails (Redd).Planetary Nebulae Formation
Stars seem so gracious from the view of the naked eye; the unimaginable fact is that they are very violent and dynamic. They keep changing in form and location, just like human beings do. They take a particular path throughout their being, through which they transform till the date of their end. A star forms from a mass of cloud dust and gas in space (Ghosts). This mass is a nebula. Its beauty is attributable to its luminous composition of ionized gasses, hydrogen and helium. An interstellar cloud explodes into billions of stars after it has received a nudge from an exploding nebula. The push causes movement inside the cloud and eventually due to the extreme heat caused by the particles, an explosion occurs, and stars form.

Black Hole

A black hole is a location in the outer space that has massive gravitational force that makes it impossible for matter to get through it. According to scientists (NASA), Steller black holes are formed as a result of a huge star collapsing or falling upon itself. After the formation of a black hole, it will proceed to grow continuously through the absorption of the mass that surrounds it.

Supernova

A supernova is a star that has undergone an explosive death that in turn brings about a massive surge of light in the space. A supernova is formed as a result of collapsing of a big star or by the abrupt re-ignition of fusion, which is nuclear in nature, in a star (NASA). A supernova results in the release of massive amounts of energy that can bring critical effects in space such as the release of enormous amounts of energy that can produce essential impact in space.

Conclusion

Planetary Nebulae occur from beautiful masses of gas and dust in space. They move aimlessly in space until the day they receive a nudge that causes an explosion to form billions of stars. Black holes and supernovae are also key features that arise from the process of Steller evolution.
