Seeking expert advice from academia. Both my bachelor’s and master’s are in the field of computer science. I have research, industry, and entrepreneurship experiences related to that field only. However, I would like to explore something new. I have always been fascinated by astronomy and astrophysics. Would it increase my chance for a Ph.D. if I have a publication relevant to the new field? Or are there other opportunities that I don’t know about yet? Thank you!
