Central region of the Perseus cluster |
Perseus cluster of galaxies, including the prominent elliptical galaxy NGC 1275 which is a powerful radio source. A close inspection of NGC 1275 shows bluish and greenish features, due to glowing gas (probably Oxygen and Hydrogen). (Perseus images and caption courtesy of Robert Lupton) |
