I'm currently a 2nd year undergrad, looking to decide which physics field to make a career out of. I'm interested in Astrophysics & Cosmology - but I don't know much about what is currently going on in these areas of science. I thought that the best way to get some idea would be to read some papers, but the ones I've come across always make me feel extremely dumb (which I am in comparison to the authors, but still). So my questions are ; how can I attempt to read these papers? Is there any place where summaries/reviews of these papers is posted? Where can I find them? Thanks!
