Now that you know more about astrology and cosmology, you might be wondering where astrophysics fits in. Astrophysics is basically like the sibling of astronomy and cosmology!
It uses laws of chemistry and physics in order to understand the birth, evolution, and death of celestial objects in space, such as planets, stars, and nebulae. As you can see, there are already clear similarities between them so things can become a bit complicated.
Astrophysics deals with the physics of the universe and this also includes the physical properties of space objects, such as their density, temperature, luminosity, and chemical composition. There are quite blurry lines when it comes to defining astrophysics, astronomy, and cosmology because they are meant to work together. Astrophysics is a branch of astronomy. He or she will need to think like an astrophysicist to use the laws of physics in order to interpret how the planet produces energy, how it moves through space, and to learn more information about it.
Then, astrophysicists will step in to ask questions such as how that planet fits into the universe. Finally, a cosmologist will want to discover how the knowledge about that planet makes sense with the knowledge of the entire universe. Cosmology studies the structure and changes in the universe at present, while cosmogony concentrates on how the universe originated, as NASA reports.
Astrobiology encompasses biology, geology, and astronomy. It concentrates on the nature, existence, as well as search for extraterrestrial life, as Britannica reports.
Astronomy , cosmology, and astrophysics help us to better understand the world in which we live while also helping us to better understand our place in something greater than ourselves.

It studies objects close to earth like the sun, the planets and their satellites, meteorites, comets, matter clouds around the sun, and the stars.
Sub-branches like observational astronomy study the sky objects through giant astronomical telescopes, radio astronomy studies stars and galaxies with their radio waves that reach earth, planetary astronomy studies motion, composition, geology and atmosphere of planets, and astrobiology studies the possibility of life forms on planets and their satellites.
Cosmology has branches like relativity, quantum mechanics, and theoretical physics. All of these branches together study the structure and the constituent dynamics of the universe. The theories like the big bang theory, steady state theory explore the origin of the universe.
Observational and radio astronomy can be studied outside of academics. Amateur astronomy is widely popular among science enthusiasts worldwide. Astronomy will help us gain more insight about stars and planets and their atmospheres for future human settlement. Also see: The Galaxy Vs. Milky Way. References: Wikipedia. Difference between Astronomy and Cosmology.
Difference between astronomy and cosmology Astronomy Cosmology Scope of study Positions, motions, and dynamics of celestial objects like stars and planets. The origin, development and the structure of the entire universe Methods of study Observational and less theoretical Mainly theoretical and less observational Categories It is studied in different categories like- observational astronomy, radio astronomy, astrobiology, astrophysics It is studied in different theories like the Big bang theory, steady state theory, and inflationary theory Range of study It studies objects close to earth like the sun, the planets and their satellites, meteorites, comets, matter clouds around the sun, and the stars It studies the structure of the universe, the clusters of galaxies Sub-branches Sub-branches like observational astronomy study the sky objects through giant astronomical telescopes, radio astronomy studies stars and galaxies with their radio waves that reach earth, planetary astronomy studies motion, composition, geology and atmosphere of planets, and astrobiology studies the possibility of life forms on planets and their satellites.
How is it studied? Amateur astronomy is widely popular among science enthusiasts worldwide Cosmology has to be undertaken through academics as it is highly a theoretical discipline. Future scope Astronomy will help us gain more insight about stars and planets and their atmospheres for future human settlement Cosmology will help understand the large scale structure and the way it will end. Astronomers conduct observations using classical mechanics and optical methods telescopes , binoculars and other pieces of astronomical equipment like Spotting Scopes.
They document and classify what they are able to see and use a variety of techniques in order to do so. Their focus is principally on celestial objects like stars, galaxies, nebulae etc and other celestial occurrences like star clusters etc.
Astronomers observe positions, motions, movements and evolution of objects over time and sometimes spend time researching the chemistry and physics of specific celestial objects. Alternatively, Cosmologists try to understand and explain the entire evolution of the universe. They want to help answer the old-age question: how did the universe start and how did it get to where it is today. Cosmologists also study modern theories, one to note is String Theory.
In recent times, Cosmology has expanded to include the study of other specialist areas like Dark Matter and Dark Energy. Interestingly, it is through the use of numerical data collected by Astronomers, that Cosmologists infer and can advance their understandings.
Astronomy is the science of study of all celestial objects and phenomena in the universe using mathematics, physics, and chemistry. Astronomy starts with microscopic focus, observing and classifying single and specific stars, planets and gases. The science expands to a much larger scale through the study of entire galaxies and star clusters. Astronomy dates back thousands of years and has been studied for millennia. Historical findings show that civilizations including the Greeks and Egyptians observed the sky and made empirical documentations of what they saw.
