A composite image of the Perseus galaxy cluster. Visible and radio light are shown in red, while X-ray light from the Chandra Observatory is shown in blue. The unusual X-ray emissions, particularly a 3.5 keV signal, hint at the possible existence of fluorescent dark matter. The central region shows a deficiency in 3.5 keV X-rays, while outer regions exhibit an excess.

Hubble Remix: Active Galaxy NGC 1275

A stunning Hubble Space Telescope image of NGC 1275, the dominant galaxy in the Perseus Cluster. This color composite reveals vibrant filaments of glowing gas, up to 20,000 light-years long, surrounding a central supermassive black hole. These filaments, surprisingly stable despite galactic collisions, are believed to be held together by powerful magnetic fields. NGC 1275, also known as Perseus A, is approximately 230 million light-years away and spans over 100,000 light-years.

Chandra X-ray Observatory image of the Perseus galaxy cluster, showcasing the cannibal galaxy Perseus A (NGC 1275) and its supermassive black hole. Red, green, and blue represent low, medium, and high-energy X-rays. Notice the magnetic bubbles and the x-ray shadow of a smaller galaxy falling into Perseus A. The cluster is 320 million light-years away.
