Galaxy NGC 1275 is a behemoth, also known as Perseus A or Caldwell 24. It is a type of Seyfert galaxies, located about 237 million light-years away in the direction of the constellation Perseus, near the center of the Perseus cluster of galaxies. The galaxy NGC 1275 is the radio galaxy Perseus A. In fact, a set of two galaxies, the central galaxy of the Perseus cluster, and the HVS "a system of high speed" which is opposite her. The HVS system which moves at 3000 km/s toward Perseus A, certainly merge with the cluster. The central cluster of galaxies contains an extensive network of filaments Spectrals generated by the active galactic nucleus. These long filaments glowing of several million degrees, consisting of gas, extend well beyond the galaxy. They emit X-rays across the cluster. The amount of gas contained in a filament is about one million times the mass of our Sun. These filaments of 200 light-years wide, extending to 20 000 light-years. The existence of the filaments is a problem. Why are they much colder than the surrounding intergalactic cloud? | The apparent magnitude of the cluster is 12.6. | Image: Hubble Space Telescope 1.73′ view of NGC 1275.
