First off, the general word astronomy is the study of outer space and everything in it to the last detail. In order to study all that mass it has to be broken down into separate categories. These are just a few types of space astronomy. Some of the different types include planetary, solar, stellar, and galactic. Understanding the different types of astronomy might give you a basic knowledge of how things are broken down in the universe.
Planetary astronomy is a type of space astronomy which focuses on the planets and moons. All researchers who work in this field are dedicated to learning more about planets inside and outside of the solar system. Besides just studying planets, they also study the theories on the formation of these planets. The use of space craft, robotic vehicles, computer simulation and mathematical modeling are just a few tools scientists use. Some of the other things studied in this field include comets and even asteroids.
Solar astronomy is limited on what researcher can learn since the study of the sun has to be done at a moderate distance. This study can also be done on neighboring stars by helping us understand a stars life span from birth to supernova. By examining the massive gas storms, waves of radiation and heat fluctuations helps to determine the suns temperature, chemical makeup and energy. A major part of our solar system is the sun and there is so much information we still do not entirely understand.
In stellar astronomy the stars are the primary focus of this type of space astronomy. Areas that are studied in this type of astronomy include how stars are formed and their evolution. The two primary types of study include observational and theoretical. Observing the stars by optical and photographic means through studying the color and intensity of radiation flowing from the star. Taking specific phenomena that has been associated with stars, creating models and studying them are the theoretical practices in learning about stars. There are many instruments astronomers use to study stars, like allowing scientists to see wavelengths, and use the information so physical models of stars can be designed.
The Planet we live on is inside the galaxy we know as the Milky Way and Galactic astronomy is the study of our galaxy and everything inside of it including dust, stars, other planets, nebulae and stellar clusters. All the activity inside this galaxy, how it moves, the evolution, how it reacts to black holes and meteors are all areas of study. Another area of astronomy is extragalactic which studies all other galaxies besides our own. The Milky Way is the most widely studied and understood, but there were areas that we could not see because of gas and dust clouds, but thanks to modern inventions we have been able to map these clouds and begin to learn about them.
The galaxy we live in is one out of hundreds if not thousands of galaxies out there. This task has to be broken up into different specialized areas of science if we are ever going to learn about the wonders it holds. In a universe that never ends and even though our scientific accomplishments can pierce through space which gives us the ability to see light years beyond what we ever thought possible, we have only touched on the knowledge it will give us.
