Can I study astrophysics if I have only studied Physics not Biology or Chemistry in my O levels? If yes then what job opportunities are there for it? And what other major can I do with it?

Hi there, I'm currently working on my BS in Physics with plans to do an Astrophysics grad degree. However, I'm not sure if I should go Astronomy or Astrophysics. My university I attend currently does not have an astronomy degree, so I chose to do physics. (I had to go to this university...

This has been something I have wanted to do for a long time, but have never really pursued it. I have taken some courses randomly, but nothing applicable to the degrees I need to get there I am positive. So basically my question is where do I start this very long journey??

I don't know what happened, but it seems that all the "hot" research is in fields like astrobiology, cosmology, computational astrophysics, and survey science (SDSS, LSST, etc). The most popular area of astro is still extragalactic stuff (which still makes up >50% of astro research), but even...

So, I am very sure I want to study astrophysics. Ideally, I would become a researcher, but I know that this is extremely unlikely. However, I also know that I would always regret it if I didn't try. But, understanding how unlikely this is, I want to be prepared. Is there any way to study other...

Homework Statement Show that a satellite in low-Earth orbit is approximately P = C(1 + 3h/2R_E) where h is the height of the satellite, C is a constant, and R_E is the radius of the earth) Homework Equations Unsure The Attempt at a Solution I have no idea how to approach this.

hello friends. I am currently in my third year of my bachelors of science in honors astrophysics, and after some consideration, I have decided that I want to go into aerospace engineering. Up until recently, my plan was to eventually get a Ph.D and go into a career of research. However, I've...

Is there a difference between theoretical astrophysics and theoretical physics applied to astrophysics? Thanks

I posted a topic about this in the academic advisement forum... but it seems that no one really knew the answers (so it died off pretty quick). So I thought I'd ask here, maybe someone will know. Anyway, what I want to know about is particle astrophysics. From the name, I'd think that it's...

Two main questions here that google can't really help me with. Right now I do research in computational astrophysics (n-body simulations) and I think I like doing numerical simulations (I'm a pretty good programmer and I like to apply that to physics). I'm somewhat interested in particle...

I'm reading a research paper and they bring up the term "natal kick". And google didn't turn up a great explanation immediately so I thought I'd check here. Can anyone help me? Thanks.

This is sort of similar to the math theory thread. But I'm quite curious how this various from field to field, especially as it pertains to astrophysics (and pretty much all the quantitatively related sciences such as planetary sciences and applied physics). Unlike math theory though, there...

Hello, I was wondering what's the difference between an astrophysicist and a theoretical physicist? Cause they seem like the same thing?

Which schools have the best programs in computational astrophysics? Judging by their websites, Princeton and Univ. of Chicago seem to have strong programs, but I was wondering if people knew of others as well??

I really love planetary sciences, especially the science concerning the moons of the gas giants (although lots of this research is constrained by the availability of space probes). But are planetary scientists rare in astrophysics departments? In my university, almost all of them are in the...

I want to study Astrophysics but want to do so with an engineering background. Could you please suggest a proper engineering degree for that purpose? Also, What is "Engineering Physics" ? and can I study that as my road to Astrophysics?

Okay so my primary interest is to pursue cosmology. My question now is what are my chances of getting excepted on a horrendous PGRE score. I just received my scores and it was HORRIBLE like failing, think single percentage. I don't even know how I did so badly I didn't think I did that badly...

I know that you could use ScienceDaily's RSS feed, but ScienceDaily is for the general public and not for working scientists. So for working scientists, which one is best? I can obviously subscribe to the RSS of The Astrophysical Journal. But I'd prefer something that I could quickly read in...

Is there such thing? I mean, there is Astrophysics so would studying celestial bodies at the subatomic level classify as Astrophysics, Quantum Physics or does it have some other division? ( I'm sorry if this question sounds stupid but I'm not in High school xD )

Hi, I'm really keen on pursuing higher studies in astrophysics in a US university. But currently in a confused state in selecting a suitable university that does not require GRE physics test to apply. Some say i should write personally to professors of the desired field and if lucky i might...
