NGC 4945 is a striking barred spiral galaxy located approximately 13 million light-years away in the constellation Centaurus. It is one of the brightest galaxies in the Centaurus group and is notable for its prominent bar structure and extensive, well-defined spiral arms. The galaxy's edge-on orientation provides a spectacular view of its elongated shape and central bulge.

NGC 4945 is also of significant interest to astronomers because of its active galactic nucleus (AGN), which harbors a supermassive black hole. This black hole is a source of intense X-ray emissions, making NGC 4945 one of the brightest X-ray galaxies in the sky. The presence of the AGN suggests high levels of activity and energetic processes occurring in the galaxy's core, offering valuable opportunities for studying the dynamics of black holes and their influence on their host galaxies.
