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?
Like the post above me says, it depends what you mean by 'extremely risky'. With the slightly more esoteric subjects like cosmology, the hard (very hard) part is finding a job in the first place. There aren't many, and new positions are extremely scarce now that funding bodies are having to tighten their wallets quite a lot.
Astrophysics is a slightly different kettle of fish, in that 'astrophysics' is an umbrella term for lots, and lots of different subject areas.
Are you asking with a view to wondering what would be appropriate to study at undergraduate level? If so, you can't study more than a course or two in cosmology anyway, and the skills you'll get are still good so it's a non-issue. There are potentially a lot of 'astrophysics' courses to study at undergraduate, but you'll still complete the core physics curriculum, and even do a lot of the same types of work albeit in a different context to 'regular' physics majors. Thus, at the end of your degree whether you studied 'physics' or 'astrophysics' is a non-issue - both graduates are good at math, problem solving and can probably do some programming too so are equally desirable for hire with many disciplines.
That is, an astrophysics undergraduate degree will leave you as highly employable as a physics degree will (the good-level of employability doesn't mean it's either easy to get a job or you'll get a job that you'll enjoy, however).
