Space Astronomy, The Study Of Outer Space

Astronomy consists of space, stars and planets and is so vast that we have hardly even touched upon the learning potential that it holds. Because of this vast amount of area we must divide our study’s into smaller groups, otherwise the task would be to daunting. Just a few of these areas are planetary, galactic, stellar and solar. Below is a brief introduction to understanding what some of these areas do. This will give you a brief understanding of the enormous undertaking that this involves.

Planetary astronomy and science studies the planets and moons, comets and asteroids, icy satellites and dwarf planets. They study the physical mass and composition of these bodies as well as the theories behind the formation of the planets mostly within our solar system. Computer simulation, mathematical modeling, or by physical means using a robotic vehicle to collect specimens are some of the ways to help study. Research can be conducted by earth based laboratories or space exploration. They examine the dust around younger stars and how they move through space. They also study interior and exterior surfaces, what their atmospheres are like and research the study gravity.

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.

Stellar, unlike solar which studies the sun, is primarily focused on the stars and while trying to keep things basic and easily readable there are two main categories for studying them. The first, Observing, is usually done by observing the stars through high powered telescopes and photographs to understand the color and intensity of the radiation coming from stars. The second, theoretical, is the practice of creating models based on information and specific phenomena that is already none about stars then formulating theories based on those models. Instruments used to study wavelengths, stellar flare, and high temperature plasmas are some other related ways of learning about stars.

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.

Telescopes gives us a small unique chance to capture some if this remarkable universe we live in. To see some telescopes and a difference between refractor and reflector go to the Perception Optics website for pricing and free shipping.
