Galactic astronomy is the study of galaxies, their formation, structure, components, dynamics, interactions, and the range of forms they take.
Our own Milky Way galaxy, where our solar system belongs, is in some ways the best studied, although important parts of it are obscured from view in visible wavelengths by regions of galactic dust. Modern instruments, and particularly the Hubble Space Telescope, have allowed us to study galaxies other than our own in great detail.
Galacticastronomy is the study of our own Milky Way galaxy and all its contents.
Galacticastronomy should not be confused with galaxy formation and evolution, which is the general study of galaxies, their formation, structure, components, dynamics, interactions, and the range of forms they take.
The development of radio astronomy and submillimeter astronomy in the 20th Century allowed the gas and dust of the Milky Way to be mapped for the first time.
