Sample Astronomy Essay On The Universe and the Solar System

Homework Question on The Universe and the Solar System

  • The format of this paper is a question that focuses on one of the principle learning objectives such as how the Universe and the Solar System is formed.
  • With a suitable answer that covers the major concepts in that learning objective. You can see the principle learning objectives at the front of each of the listed chapters on the first page of the chapter, the learning goals and change the wording into a question.
  • You can also refer to the main ideas by looking at the summary of key concepts found at the end of the chapters. Any of those questions or concepts would be an appropriate topic for writing the essay.
  • After the paper is complete, you should also write a second reflective essay (at least a page) explaining why you chose your topic, what major understandings you learned from writing the paper, and why this topic is important in the overall theme of this course, namely, observational astronomy.

Homework Answer on The Universe and the Solar System

The solar system is approximately 4.5 billion years old. According to scientific evidence, the formation of the solar system was completed about 100 million years after the sun was formed which took about one million years (Chambers & Mitton, 2014; Ward & Brownlee, 2004). The process of star formation from a collapsing molecular cloud of dust and gas defines the formation of the solar system. This is the theory of the solar nebula star.

According to this theory, the universe and the solar system were formed through a rotating cloud, which was compressed by a passing shock wave (Ward & Brownlee, 2004). The cloud collapsed into a flat, spinning disk characterized by a prostar at its center. The planets were made from the flat spinning disk through a process of coagulation and condensation of the material from the compressed rotation cloud, which were largely composed of dust particles (Taylor, 2001).

One of the initial processes by the formation of the planets was the nuclear fusion process. This process began in the central star making it bigger and luminous enough (Taylor, 2001). The components of the universe and the solar system indicate that the solar nebula theory is the most plausible in explaining the formation of the universe and the solar system (Chambers & Mitton, 2014).
