Assalamu Alaykum, Is becoming an astrophysicist/astronomer acceptable in Islam? It would only consist of research in astrophysics/astronomy. It would not involve teaching, nor would it involve working in planetariums and science museums. The job of astrophysicist/astronomer consists in: - Programming, writing computer code to analyze observational data or to make models/simulations of phenomena. - Writing scientific research papers that may be published in scholarly journals. - Writing many emails. - Filling out paperwork to get funding for our projects. - Traveling very frequently to many countries to present our research findings at scientific conferences and lectures, and to meet other astrophysicists/astronomers. - Traveling frequently to many remote parts of the world (on top of mountains) to make observations with optical or radio telescopes. Note that “astrophysics” and “astronomy” are the same thing. But they must not be confused with “astrology” which is something totally different.
