The Current Status Of Galaxy Formation

“The power and beauty of physical laws is that they apply everywhere, whether or not you choose to believe in them. In other words, after the laws of physics, everything else is opinion.” An astrophysicist by training but an energetic, effective communicator by nature, Neil deGrasse Tyson offers a brief introduction into the origin and evolution of the universe. Compacting the entirety of the universe into a conglomeration of two-hundred pages requires Tyson to move swiftly through his analysis, often employing wit, anecdotes, and science-fiction references to maintain his narrative have an ecstatic atmosphere. His goal throughout this book is as astronomically large as the cosmos itself: to create a scientifically literate population. Speaking

The article ‘On the Recentness of What We Know,’ written by Verlyn Klinkenborg, is a pleasant read about the author’s fondness of astronomy and his insight regarding the science of it and knowledge gleaned from it. Klinkenborg recounts a few of his star-gazing memories and then proceeds to analyze the effects cosmological discoveries have on him personally and humanity in general. The author shares bits of theoretical history of the universe and information on the early astronomers whose hypotheses have developed that history. He goes on to reference various well known discoveries throughout the years and marvels at how drastically information in recent years has changed the stories of our universe.

Have you ever looked up at the sky on a clear night and wondered, “what else is out there?”. What could possibly lie beyond the beautiful blanket of stars that we see with our naked eye? Nebulas are one of many galactic phenomena that lie beyond the Kuiper belt. Mysterious and fascinatingly beautiful sights to behold, they have more of a purpose than just painting the galaxy backdrop with color. I’m not a diehard fan of astronomy and to be perfectly honest I find it difficult to follow most of the information I have learned. However, when I came across pictures and information on nebulas I was instantly fascinated. From how and why they’re formed, to what they do for the galaxy, I’m excited to take you on an intellectual journey though nebulas.

Understanding of the processes of stellar evolution came as a result of twentieth century advances in both astronomy and atomic physics. Advances in quantum theory and improved models of

To discover what the universe is made of and how it works is the challenge of particle

Neil DeGrasse Tyson is an exceptionally qualified individual to address the issues brought up over the course of the book. He received his bachelor’s degree in physics from Harvard University in 1980, master’s degree in astronomy from the University of Texas at Austin in 1983, and master’s and doctorate’s degrees in astrophysics from Columbia University in 1989 and 1994 respectively. Tyson has been the director of the Hayden Planetarium at the Rose Center for Earth and Space since 1996, as well as a research associate for the American Museum

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

“The many accidents of physics and astronomy have worked together to our benefit and shows that in some sense the universe must have seen us

In inspiring people to have the passion in understanding the universal laws that govern us all, Professor Stephen Hawking reminds us on his speech for his 70th birthday to “remember to look up at the stars and not down at your feet” (enoch, 2012). Many scientists have been “looking up” and have discovered answers to the many questions that we have of the universe for ages. They have constructed theories, launched satellites, observed stellar phenomena, and even sent living beings in space to gain more understanding of the existence of everything. After centuries of research and observation, there are still some aspects of Astronomy that are still to be explored. One of them is the evolution of the Solar System, which is composed of the Sun and everything that travels around it. This includes eight planets and their natural satellites such as the Earth’s moon; dwarf planets such as Pluto and Ceres; asteroids; comets and meteoroids (Solar System Exploration, 2014). The Solar System is located in the Milky Way Galaxy, which is a part of a galactic group under the Virgo Supercluster. Figure 1 shows the location of our Solar System in the Universe. Many theories have been proposed on how the Solar System existed, but none has been completely successful. This spans from the time of the Ancient Greeks to the present 21st Century. As of now, the widely accepted theory is the Nebular Theory, which describes how the Solar System started as a large cloud of gas that contracted under

Chapter seven opens with the assumption of a cosmography concept of the universe from all history civilization. In particular, the perception of ANE society in terms of how they described the picture of the universe as a whole. Today, one can create a better map with the main features of the universe due to science and technology has evolved. At the same time, to have a better understanding of how the earth, the sun, and starts functioned within their area of operation.

He has scaled the mountains of ignorance, he is about to conquer the highest peak: as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.”[v] Though Jastrow treats the issue as settled and declares that scientists have finally been “defeated,” it is too early to reach any judgements on the implications the new cosmology has for both science and religion. Our image of the origin of the universe is not yet complete and further investigations must be conducted before the towel is thrown in. Science has still much to offer to help us understand how the universe came to be. Therefore, let us now attempt to solve the cosmic mystery of creation by referring to the great scientific minds as our guide. Let us now rewind the story of the big bang and look into the origins of the universe.

Throughout the second chapter of Investigating Astronomy: A Conceptual View of the Universe, authors Timothy Slater and Roger

In Thomas Kuhn’s paradigm cycle, normal science inevitably leads to an anomaly, which eventually leads into a crisis. If the current existing theory in the paradigm fails to solve the puzzles of normal science, it will eventually call for a new theory to take its place. Kuhn further expresses that, although, normal science holds the objective of creating boundaries and structure in the scientific community, and thus, suppressing ideas and findings outside of this structure, normal science is also a driving force of the creation of anomalies and an eventual paradigm shift. Scientists’ ultimate goal is to unravel the truth of the universe. Normal science and the existing paradigm are successful, in the beginning, in aiding and justifying scientific findings of that time. However, as experiments and research methods progress and advance with time, the polished version of the theories and concepts may start to conflict with the initial paradigm. It is the success of normal science, which is inevitable through time, that leads to an, thus, inevitable crisis. The increasing precision and improvement of understanding the paradigm, makes the paradigm an easier target to find

In October 1962, Stephen touched base at the Bureau of Connected Arithmetic and Hypothetical Material science (DAMTP) at the College of Cambridge to do investigate in cosmology,

Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assumed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation to
