Galactic Nucleus

The galactic nucleus is the central region of a galaxy, typically home to a dense concentration of stars, gas, and dust. In many galaxies, including our Milky Way, it contains a supermassive black hole, which can be millions to billions of times the mass of our Sun. This area often displays high levels of activity, including star formation and the emission of energy in forms like radio waves and X-rays. The nucleus is crucial for understanding a galaxy's structure, dynamics, and evolution, as it influences the surrounding regions through its gravitational pull and energetic processes.
