- What’s the difference between Astronomy, Astrophysics and Cosmology?
You may be wondering this so you know what to study in school, because they all seem the same. This video will briefly help you distinguish between the 3 as we dive deeper into cosmology in future videos
Astronomy is a blanket term that generally covers all study of stars, planets, and space in general. This means that an Astronomy degree can put you well on your way to studying Astrophysics or Cosmology in your professional field, so don’t feel like you are missing out on anything if you choose this as your major. For lack of better terms though, you can think of Astronomy as primarily focused on observing the skies.
Astrophysics applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. If you want to study Astrophysics in college, you could start with an Astronomy degree, then you should aim to (eventually) complete a doctorate in astrophysics, and then take on a post-doctoral position in astrophysics. Astrophysicists can work for the government, university labs and, occasionally, private organizations.
Cosmology is similar to Astrophysics, but deals with phenomena on a larger scale. Whereas astrophysics is concerned with the physics and evolution of stars and galaxies, Cosmology is concerned with the birth, evolution and death of space itself and these larger cosmological structures like superclusters and voids. Cosmologists ask questions like, how did the universe begin, why is it expanding, and how will it die? Cosmologists have similar schooling as Astrophysicists, focusing their advanced degrees on Cosmology after having a background in Astronomy. Cosmologists can also work for the government, university labs and agencies such as NASA and the European Space Agency.
To recap:
Astronomers observe positions, luminosities, and motions of stars, planets, and other celestial bodies.
Astrophysicists study the physics of how all of these objects behave in space
Cosmology studies the existence of larger cosmological structure and the birth and fate of our universe as a whole.

Cosmology: large scale of the universe
Great video! I want to go into this field but I’m not quite sure which one I want to choose, but it’s still very early and I think I will discover that as time goes on.
Go for it! That's awesome. You should check out my new series where I cover an Astronomy Masters Program as I learn everything.
@@SpaceButMessier ok, I’ll make sure to do that!
Me too
Bro I like to study everything about Universe and interested to do research. Which should I choose?
Excellent video. The Chronoverse is the cosmology of Philochrony. Philochrony is the theory that describes the nature of time and demonstrates its existence. Time is magnitive: objective, Imperceptible (intervals) and measurable (duration).
Wow, very cool. I'm going to read more into this!
Hi! Thanks for this helpful video. I'm a senior high school student in Türkiye who was always amazed by space, astronomy kind of stuff. I grew up watching and consuming all knowledge about stars, blackholes, etc. And I'd love to spend the rest of my life researching about them, making money while doing so. However, in Türkiye aside from cosmology, there aren't even decent astronomy or astrophysics license degrees. We only have physics and astronomy degrees. however, astronomy degree is so untouched that there is only 1 astronomer who graduated from there. My current uni exam score is 70/80 but astronomy only requires 30/80 and i don't wanna waste my hardwork either. It's education is not enough for most of its students. There are only one or two decent astronomers graduating in every few years. It's difficult, as it should, but education is not enough. I would consider studying physics as a licence, then studying astrophysics or astronomy for masters degree. However, im really NOT into material physics. And you have to study those for 4 entire years at physics degree. If you don't have passion it would be a waste of those 4 years. Can i still be an astronomer if i don't wanna study major league physics? My familys income is not bad, but we're in an economic crisis rn, and they can't afford my uni costs if i study abroad with no scholarship. And i really wanna be successful in my own country.. I'm so hopeless, ain't i. What is your opinion? I wanna get involved in astronomy in a non physics-based way and be successful. I'm planning to study translation studies so i can get to know english and another 2nd language better, so i can somehow study astronomy abroad easily. Is age 22 too late to start studying astronomy degree? If i want to study for a bachelors degree as well?
What a great question!! First I want to say congrats on finding what excites you and I have no doubt you will succeed. I believe in you!
Second, Astronomy HEAVILY relies on physics and any physics coursework would not be a waste of time. Most astronomers need or have a lot of physics background for their research. So with that, I would say, go for it! But ion the other hand, just because you only need a 30 to study Astronomy, that doesn’t mean it would be a waste of your intelligence. Do what excites you. Period.
And also, I didn’t started learning Astronomy on my own until I was 21. I just finished a M.S. Astronomy as a 30 year old!
Second,
@@SpaceButMessier that's very inspiring !! Knowing i figured out im into astronomy when i was child is very encouraging in some way. If i had chance, id study astronomy then study physics as license but in this scenario, do you think studying physics will be worth it?
I am trying to make a point to my colleagues about the effectiveness of early intervention versus late intervention. My question is, how early (miles) would you have to intervene, to deflect the meteor that created the Chicxulub crater and wiped out the dinosaurs, from hitting the earth, if you could only exert one pound of pressure? Make any reasonable assumption you need to produce that model. Then how much force would be required to deflect that same (hypothesized) meteor from hitting the earth if the intervention was delayed until the meteor was equivalent to the moon’s orbit from the earth? (One thumbs up for each answer, not easy to get a thumbs up from me, sorry 😊 )
Wow I love this and honestly not sure why it took me this long to see it. I'll do some work on this

Thank you. I have always wanted to study the space (astronomy) but as I kept getting introduced to newer fields like astrophysics and cosmology, I kept getting more and more confused. Since it seems like astronomy is the more general field, it seems like it would be the best to start with it and progress to astrophysics or cosmology, depending on what I'm interested in in the long run.
I would say that focusing on either Astronomy or physics would serve you really well for both of those paths
@@SpaceButMessier Thank you for the suggestion.
@@SpaceButMessierSorry for the late comment, but if I want to do either of these, I major in astronomy correct? And a minor in physics then for astrophysics?
Thank you for making the video, as a high school student interested in pursuing space related science, I finally have a deeper grasp of the understanding of these different fields. 😌😌
Short, to the point and helpful. Just the way I like it. Thanks a lot!
You got it! Any lingering questions I can answer in the next, deeper video?
@@SpaceButMessier I don't currently have any questions but I am surely looking forward to the video!
This was uploaded on my b day.
Dude nice
Please give more and more information about this field also tell about institutes
thanks bro, god bless you for making this video . my life is a little simpler now
You got it man. I’m glad it helped!
Astronomy: the studies of the stars and other celestial bodies like planets.
Astrophysics: Explain the life and death of stars, planets, galaxies, etc.
Cosmology: Used to explain the large scale properties of the universe; explain the life, birth, and death of universe.
Hey! this video perfect my doubts are Crystal Clear thank you so much sir
I'm in class 11th
I want to become a astrophysicist
What should I after class 12th
Hey! I'm sorry I'm late to this one, but you should consider Physics. It'll set you up well for Astrophysics in grad school
Hey bro! Is there any of your video which can guide me to choose one from these?
I don’t have any more videos on this topic, but what other info are you looking for?
Wow 🥺 brother
U explained very well
Thanks so much! More to come :)
Fun fact Reed Richards mr. Fantastic Marvel Comics and dr. Rajesh Koothrappali from The Big Bang Theory brought me here
Brought you to be interested in this? Or brought you to this specific channel? Either way, awesome! And welcome
Nicely explained ❤️
Thanks so much!
which universities offer a bechlors in astronomy? ive been trying to search for so long but i cant find any potential ones
I'm pursuing bachelor degree in Electrical engineering and I want to become observational astronomer. My question is that if I choose Astronomy in my master degree, do I have to choose specifically Observational Astronomy or I have choose Observational Astronomy after completing my phd in Astronomy?
Kathan, great question! Nope, depending on where you go, a general astronomy degree will work perfectly
@@SpaceButMessier thank you...
Thank you very muchh .. We're waiting the next vd about cosmology 🖤🖤
Comin right up. I had to take a step back but I’m back in it now. Anything in particular you wanna learn about?
@@SpaceButMessier Actuelly I wanna ask about astronomy how much years it would take for learning it?
Oh! Not long at all. How about this. I am finishing my Masters Degree in Astronomy in one year. Why don’t I teach you everything I learn as I learn it so you get a feel for the pacing of this program? You can have a firm grasp on Astronomy I’m a month. I would say a year for a full hnderstamding
@@SpaceButMessier Ohh reallyyy but I'm not in America do u mean online ?
Yeah I mean through here. It’ll be fun!
Are these 3 are the branches or physics 🤔 you consider these the branches
Astronomy is the best one
But they're all so cool! How do you choose?
whats the difference in cosmology and astrophysics
Study cosmology is my dream,from india , preparing for one of the toughest entrance exam in science jee advanced
Really?! You can do it. Let me know if I can help in any way
Can you tell me where I can study cosmology
@@SpaceButMessier thanks 🙂
Is ISRO good for cosmology?
I’m gonna do some research for you and find some options
Thanks bro
you got it bro
Heyy!!
I want to become Cosmologist. So which degree should I pursue after my 12th??
I would say that you should consider a degree in Physics. This will give you the perfect foundation to study Cosmology in undergrad and graduate school
@@SpaceButMessier can I become astrophysicist after completing areospace engineering.
Sir which is best ? Please tell me ?
All are great, just different!
i m from a country where there is no place to take admission in astronomy , astrophysics and even there is no single department like this in any university.I have mistakenly chosen biology as my major due to some family pressure . is there any way to pursue my career in any of these Fields ..i have done my intermediate in biology /medical but now there's no place where i can take admission in math and physics.what should i do plz guide me i m from Pakistan
Can you tell me a little more why math and physics are not available? Do you have access to nay online educaiton?
@@SpaceButMessier actually i have chosen pre medical as my major in intermediate and now i m unable to take admission in any undergraduate program of physics and math and related subjects coz universities only offer such degrees to the students who had chosen math as their major in intermediate... so i am bound to continue my undergraduate degree in any biological sciences related fields.. i have internet access and i can seek guidelines online but i have eyesight issue so my doctor has advised me not to use cell phone or any other such device .. m really worried now .. i have such a love for astronomy since childhood but there's no university in our country which offer undergraduate program in astrophysics, Astronomy and even cosmology is such a new word here.. so i just don't want to complete my undergraduate degree without any knowledge of astronomy.. i have already lost chance to take admission in physics and math department because of biology which i have Chosen as my major due to family pressure...
Ayesha, this breaks my heart. Are you able to go back and redo intermediate in math instead of biology? Have you asked? Your family should not decide what you study, only you should.
@@SpaceButMessier that's really difficult to go back in these days when education is affected due to covid-19.. i have spent 2 years in doing this degree I really can't go back now..
While I agree that it would be difficult... this affects the next 40 years of your life. Is it really worth it to stay on this path? what's two years compared to your whole carreer?
Hello
Hey!! Thanks for watching
Can I get a PhD in astronomy after a Master's in Meteorology?
Yes! Most schools would say those are in the same field so it shouldn't be a problem.
Are you still going to school for astronomy?
Yes! Finishing my first year in my Masters program
@@SpaceButMessier Do you post videos of your podcast?
Yes!! I have a couple to catch up on
