What is the Definition of Astronomy – Before continuing your study on astronomy, you should know first about what is the definition of astronomy. Moreover, you also need to learn everything related to astronomy deeper. Let’s talk a little bit to increase your intention to continue your study on astronomy.
The Overview of Astronomy Science
Astronomy is included on the natural science. In specific, you are about to learn everything related to celestial objects and phenomena. As a student, you will explore more about the sun, moon, stars, planets, comets, galaxies, gas, dust, and many more.
To support the knowledge, you also need to be ready to learn mathematics subject, physics subject, and chemistry subject. The interesting part about astronomy is that this is the oldest natural science which has been learned since Babylonia, Greek, Indian, and many more.
The Use of Analytical Models and Computational Numerical Simulations
As an astronomer, your job is to contribute and practice your knowledge with the support of analytical models and computational numerical simulations. By using analytical model, you know what is going on or the latest issues on astronomy. Computational numerical simulation is useful to reveal the existence of phenomena as well as the effects.
Let say, if you learn about gravitation you have to be supported by radio telescope and do the research by using self gravity system. This is the same if you want to explore more about the Big Bang theory. You may support yourself with Hubble Space Telescope and analyze it by using expanding universe theory.
Subfields on Astronomy
There are also several subfields you can choose if you learn more about astronomy. First, you may choose solar astronomy. Just like the name of the subject, you are about to learn deeper about solar system such as the sun, stars, and its phenomena. Second, you also choose to learn planetary science. This subject is focus on exploring planets, moon, dwarf planets, comets, asteroids, and many more. Everything about planets is explored deeper in this subject.
Third, if you are curious about stars and stellar evolution, you should take stellar astronomy. In specific, it is the way to learn stars formation and all phenomena related to it. Fourth, there is also a subfield known as galactic astronomy. This is the place to learn solar system such as Milky Way, dust, stars, and other objects along with its phenomena.
Fifth, try to take extragalactic astronomy if you really want to know about formation and evolution of galaxies. The last subfield is physical astronomy in which you will learn more about cosmology. In this subfield, you are about to learn the universe as a whole.
