    This is very similar to your other question... I'll post the same thing i said before and then elaborate a bit:

    The general groups of astronomy that i can think of are:

    Observational Astronomy

    Cosmology

    Astrophysics

    The first deals very much with telescopes and the collection of data from space. They are very much experimental scientists and spend a lot of time learning how to use/improve the equipment that they use so they can get better data next time.

    2nd type focus on the universe as a whole and try to understand the beginning and end of the universe. They don't spend much time worrying about the individual stars and planets or even individual galaxies really... (although galaxy formation is technically a cosmological issue).

    They really look at the BIG picture and how the whole universe works and evolves.

    3rd type mix Physics and maths knowledge with Astronomy to try and work out mathematical models for how observational phenomena work.

    For example You get Stellar astrophysics, which is a mathematical study of how stars evolve and function. They describe the life, death, workings, reactions, movements of stars with equations and mathematics.

    All astronomers rely heavily on maths and physics however.

    !!!ELABORATION!!!

    Ok, this focuses more on the differences between the different studies...

    Basically, some of the studies like Observational stuff focus heavily on the collection of data, but not really the processing of such data. (the scientists obviously process it and try to find some meaning from it... but they don't use as complex methods as some of the other areas)

    Other ways in which the different fields... differ... is in their scale.

    Observational stuff generally sticks to planets, stars, galaxies... sort of "normal" space levels... Things you can imagine in your head.

    Whereas cosmology deals with the VERY big, it deals with huge scales and huge time scales.

    Other types of astronomy can deal with the VERY small, looking at the quantum nature of space... or the interactions of microscopic dust in nebula.

    So they differ in Methods and Scale really... But All astronomers are trying to understand how the universe works and write this down in a clear mathematical form.

    We want to know how stuff works lol

    It is not clear what your question is about. The fields of astronomy, physics, and astrophysics contain a number of sub-disciplines ranging from broader cosmological studies to specific studies of star composition, star distribution, the physics of stellar motions, and the nature of interstellar gasses and dust clouds.

    In addition, people in these fields are involved in the development of new instrumentation, including space probes, satellites, radio telescopes, interferometers, and many more types of devices. To learn more about what is involved in the study of each of these sub-disciplines, run an internet search on each one.

    Good luck!

    Light travels faster than sound. This is why some people appear bright until you hear them speak.
