But do I absolutely have to study physics to study astronomy?
Physics and mathematics are important components of the study of astronomy since they both help in explaining why the planets and the universe in general is how it is. If your aim is to study pure astronomy then yes, you would need a solid grasp of physics and mathematics.
But if your interest exceeds the physical nature of our analysis of the universe, then you might check out fields like astrobiology and astrochemistry that delve into more intricate details of the biological and chemical aspects of the universe. Astrobiology, as the name suggests, is the study of biology within the realms of space. Similarly, astrochemistry is the study of the various chemical reactions that resulted in the universe being created the way it is.
Astrobiology.
Astrobiology is the study of life in the universe. The search for life beyond the Earth requires an understanding of life, and the nature of the environments that support it, as well as planetary, planetary system and stellar processes.

To provide this understanding, astrobiology combines the knowledge and techniques from many fields, including astronomy, biology, chemistry, geology, atmospheric science, oceanography and aeronautical engineering. Astrobiologists can work alone on particular scientific questions, but often astrobiologists from different scientific disciplines work together to examine complex questions that no one field can answer alone.
Astrochemistry.
Astrochemistry is the study the chemical composition – mostly molecules and ions – that exists in outer space, including those that make up the gaseous matter of future stars, suns, and even whole solar systems. Some of those chemicals, like hydrogen, also exist on earth. Others exist only in space. All, however, have a role to play in the composition of the universe, and it’s the mission of an Astrochemist to figure out what that role is.

Astrochemists are part Astronomers and part Chemists. They intensely study the periodic table — but within the context of space rather than of Earth. As an Astrochemist, you don’t only observe stars, but you also examine, analyze, and dissect them. Astrochemists take a much closer look and study the different aspects of all the fascinating objects in the universe on a molecular level in hopes to answer questions how they were formed.
Astrophysics.
Astrophysics is the part of astronomy that utilizes the standards of physics and science to learn the idea of the galactic objects, instead of their positions or movements in space. Among the objects considered are the Sun, different stars, universes, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are inspected over the full range of the electromagnetic spectrum, and the properties analyzed incorporate luminosity, density, temperature, and chemistry.

Since astrophysics is an extremely wide subject, astrophysicists apply ideas and strategies from numerous orders of physics, including mechanics, electromagnetism, factual mechanics, thermodynamics, quantum mechanics, relativity, atomic and molecule physics, and nuclear and sub-atomic physics.
By and by, current galactic research frequently includes a generous measure of work in the domains of hypothetical and observational physics. Some topics of study for astrophysicists incorporate their endeavors to decide the properties of dark matter, dark energy, and black holes; the science of time travel, wormholes or the multiverse; and the inception and extreme destiny of the universe.
Topics likewise considered by hypothetical astrophysicists incorporate Solar System development and advancement; stellar dynamics and advancement; galaxy formation and development; magnetohydrodynamics; large-scale structure of matter in the universe; origin of cosmic rays; general relativity and physical cosmology, including string cosmology and astroparticle physics.
Cosmology.
Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is “the scientific study of the large scale properties of the universe as a whole.”

Cosmologists puzzle over exotic concepts like string theory, dark matter and dark energy and whether there is one universe or many (sometimes called the multiverse). While other aspects astronomy deal with individual objects and phenomena or collections of objects, cosmology spans the entire universe from birth to death, with a wealth of mysteries at every stage.
History of astronomy and cosmology.
Humankind’s comprehension of the universe has advanced by leaps and bounds in the last couple of centuries. In the early history of astronomy, Earth was viewed as the focal point of all things, with planets and stars orbiting it.
In the sixteenth century, Polish researcher Nicolaus Copernicus recommended that Earth and different planets in the solar system in reality orbited the sun, making a significant contribution in the comprehension of the universe. In the late seventeenth century, Isaac Newton determined how the powers between planets — explicitly the gravitational powers — interfaced.
The beginning of the twentieth century brought further insights into appreciating the immense universe. Albert Einstein proposed the unification of existence in his General Theory of Relativity. In the mid-1900s, researchers were discussing whether the Milky Way contained the entire universe inside its range, or whether it was just one of numerous accumulations of stars.
Edwin Hubble calculated the distance to a fuzzy nebulous object in the sky and determined that it lay outside of the Milky Way, proving our galaxy to be a small drop in the enormous universe. Utilizing General Relativity to lay the structure, Hubble estimated different systems and verified that they were surging far from us, driving him to reason that the universe was not static but rather expanding.
In ongoing decades, cosmologist Stephen Hawking established that the universe itself isn’t boundless but however has a distinct size. Notwithstanding, it comes up short on a definite boundary. This is like Earth; in spite of the fact that the planet has a definite size, an individual going around it could never discover the “end” however would rather always circle the globe. Hawkings additionally recommended that the universe would not proceed on everlastingly but rather would at some point end. I recommend reading Hawkings book, A brief History of time. Stephen Hawking clarifies the mysteries of the universe. In this best-selling book. Find the latest price here.
Difference between astronomy and astrophysics.
Astronomy is the study of the universe beyond the earth’s atmosphere. The main branches are astrometry, celestial mechanics, and astrophysics.

Astrophysics is the branch of astronomy concerned with the physical processes associated with the celestial bodies and the intervening regions of space. It deals principally with the energy of stellar systems and the relation between this energy and the evolution of the system.
So, astronomy is sort of a top level science that covers any scientific explorations of space beyond our atmosphere and astrophysics is a branch of astronomy that is concerned with the actual physics of stars, planets, black-holes, etc., their formation, evolution and ultimately their future.
For example, if you have a telescope in your backyard and you like to observe the night sky and make star charts and learn about our solar system then you are an amateur astronomer but if you like to use equations to calculate how big does a star have to be in order to become a black hole one day – well then you are an amateur astrophysicist.
Related questions.
If other galaxies all seem to be rushing away from us, doesn’t that place us at the center of the universe?
No, because if we were to travel to a distant galaxy, it would seem that all surrounding galaxies were similarly rushing away. Think of the universe as a giant balloon. If you mark multiple points on the balloon, then blow it up, you would note that each point is moving away from all of the others, though none are at the center. The expansion of the universe functions in much the same way.
Will the universe end? If so, how?
Whether or not the universe will come to an end depends on its density — how spread out the matter within it might be. Scientists have calculated a “critical density” for the universe. If its true density is greater than their calculations, eventually the expansion of the universe will slow and then, ultimately, reverse until it collapses. However, if the density is less than the critical density, the universe will continue to expand forever.
What is the Hubble telescope used for?
Although NASA’s Hubble Space Telescope is probably best known for its astounding images, a primary mission was cosmological. By more accurately measuring the distances to Cepheid variables, stars with a well-defined ratio between their brightness and their pulsations, Hubble helped to refine measurements regarding how the universe is expanding. Since its launch, astronomers have continued to use Hubble to make cosmological measurements and refine existing ones.
What should I choose between astrophysics and aerospace engineering?
The question is what you really want to do. Do you want practical knowledge of the things like aerodynamics and technologies related to it, or you want to enter into theoretical research of universe and celestial bodies.
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It involves fields like fluid mechanics, material science, aircraft engineering, avionics etc.
Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to ascertain the nature of the heavenly bodies, rather than their positions or motions in space. It involves studies like radio astronomy, Optical astronomy, quantum mechanics, thermodynamics, relativity and dark matter, particle and nuclear physics, atomic and molecular physics etc.
So it is clear that aerospace engineering is more practical subject as compared to astrophysics which involves a substantial amount of work in the realms of theoretical and observational physics. Know about your strengths and also your passion. If you are good at practical knowledge, go for aerospace, otherwise if you want to study deeper concepts of astrophysics using scientific laws, mathematical studies then astrophysics is better.
