Query by jimaistro: What is the difference between astronomy and cosmology?
What is the difference involving astronomy and cosmology? Are they the very same matter? Also what is astrophysics?

astronomy is the review of the stars.
cosmology is the research of the origin and development of the universe.
Astrophysics is the research of physics in space and how it interacts with factors, and what doesn’t apply to our normal realm of physics. Like a black hole, it has it’s personal sort of physics, Quantum Physics.

Query by On the fence: What’s the distinction between Astronomy and Astrophysics?
Judging by the names, my guess would be:
Astrophysics: Review of the physics and framework of the sky and what it incorporates (planets, and so forth).
Astronomy: General review of the sky, planets, and so forth and basic behaviour of it without having heading also deeply into the physical make-up of it.

Cosmology is the study of the universe taken as a whole. At the current size of the universe, cosmology deals with structures no smaller than superclusters of galaxies. Astronomy deals with structures smaller than the universe as a whole, such as galaxy clusters, galaxies, stars, black holes, supernovae, planets and so forth. Cosmology is more theoretical than astronomy, and astronomy is more observational than cosmology.

Astronomy is the study of the stars, planets, nebulae, etc. in the known universe, their movements, and their creation (if you are lucky enough to see the creation or destruction of anything-everything lasts so long that it is really very difficult to see anything happen). Cosmology is the why things work of the Universe. It studies quarks, bosons, leptons, gluons, and other particles, as well as the shape of the universe, its origins, and the investigations of theoretical phenomena.

astronomy:The scientific study of the universe and the objects in it, including stars, planets, nebulae, and galaxies. Astronomy deals with the position, size, motion, composition, energy, and evolution of celestial objects. Astronomers analyze not only visible light but also radio waves, x-rays, and other ranges of radiation that come from sources outside the Earth’s atmosphere
astrophyscis:
The branch of astronomy that deals with the physical and chemical processes that occur in stars, galaxies, and interstellar space. Astrophysics deals with the structure and evolution of stars, the properties of interstellar space and its interactions with systems of stars, and with the structure and dynamics of clusters of stars such as galaxies.

space is really big
there r lots of stars in space
there r aliens in space. they r really cool
