How hard is it to study astrophysics?? I am starting uni next year and I was thinking about astrophysics.. So can anyone tell me how hard is it (i know it's diferent from person to person but i was thinking you could take more objective approach to this matter) and do you have to be a "genius"...

hi I'm a 28 year old looking to study for a MPhys (Hons) degree in Physics with Nuclear Astrophysics. i left school at 16 with good gcse`s all A`s and B`s (maths A physics A) but had to go into full time work to support myself. Would it be a problem getting onto a course without A levels and...

Astrophysics; Money matters... ?? Hi, A little intro to help you understand. I'm from India in 12th grade or A-Levels, and was applying to British Uni's for Undergrad studies. I was thinking either B.Sc Physics/Astrophysics (1st Priority) or Engineering preferably Aero Just to get a...

I've been looking into meteorite impacts and large meteoroids passing by the Earth, and I started thinking about the physics of all that. And in the course of my playing around with the numbers, I found something that can't possibly be right, but I'm not sure what I'm doing wrong. Put simply...

hi, i am a first year student in an under-graduate inst. i have a lot of interest in astronomy and physics and wish to pursue research work in this field. however i have limited tools in terms of knowledge as this is only my first year. So can you suggest me some research project topics that...

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...

Does anyone know what the top universities with astrophysics programs are? I was looking over University of Chicago and University of Arizona lately, but which one would you consider to have a better program?

Hi all, Due to medical reason, I have problem with noises, and I am graduating from M.Sc soon, I am looking for PhD program in US, Canada, Europe (Australia?) Can you please suggest which good school which is situated at rather rural area, yet strong in physics. My research interest is...

I am a third year graduate student in physics. I came here wanting to do Theoretical studies of dark matter. But there really isn't much money in that. Plus the fact that only first year TA's get jobs in the summer hurts alot. I heard the job outlook for Theoretical Physicist isn't that great...

Hi guys, I am an high school student from italy and I am a junior. I am looking for my path carrer, which is very difficult to find. I would like to be an astrophysicist, but on the other hand I am really interested in theoretical physics. I wonder which the difference between an astrophysics...

Apologies if this is in the wrong forum. I was just wondering if there was anyone in the field here that would have some extra time in answering a couple of strange questions dealing with astrophysics, biology, nuclear physics and some other things I'm not sure what to label. It's for fiction...

I've done some searching on this forum and elsewhere and from what I can tell, the book Introduction to Modern Astrophysics by Carroll and Ostlie is an excellent place to begin learning about the subject. I believe the introduction to the book states that anyone with a calculus based first-year...

Hello Its 2010 now and I am not really up to date with careers. Is it still an extremely risky to go into astrophysics and/or cosmology? Can you guys tell me how things are going for scientists of all branches if you know? Thanks
