 "Galactic
astronomy is the study of our own
Milky Way galaxy and all its contents. This is in contrast to
extragalactic astronomy, which is the study of everything
outside our galaxy, including all other galaxies.Galactic astronomy
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.Our own
Milky Way galaxy, where our
solar system belongs, is in many ways the best studied galaxy,
although important parts of it are obscured from view in visible
wavelengths by regions of
cosmic dust. The development of
radio astronomy,
infrared astronomy and
submillimeter astronomy in the 20th Century allowed the gas and
dust of the Milky Way to be mapped for the first time."
