Galactic mapping is a field of astronomy that involves studying and mapping the distribution of stars, gas, dust, and other objects within our Milky Way galaxy. This research area aims to gain a better understanding of the structure, composition, and dynamics of the Milky Way, as well as its evolution over time. Galactic mapping often involves using telescopes and satellites to observe the galaxy at different wavelengths of light, such as radio, infrared, and X-ray, and creating detailed maps of the different components of the Milky Way. These maps can help astronomers identify regions of star formation, study the distribution of dark matter, and investigate the galaxy's spiral arms and other structural features.
