Most of the ingredients are hydrogen and helium. These cosmic lightweights fill the first two spots on the famous periodic table of the elements.

The Perseus galaxy cluster contains 190 galaxies and lies about 225 million light-years away.

This Hubble Space Telescope image shows NGC 1275, a galaxy located in the center of the Perseus cluster. The red threadlike filaments are composed of cool gas suspended by a magnetic field
This image from the Japanese Advanced Satellite for Cosmology and Astrophysics shows the X-ray glow of the 100-million-degree Fahrenheit gas that fills the Perseus cluster. The white box indicates the area explored by the Suzaku X-ray telescope to detect chromium and manganese. The image is about two degrees wide, or four times the apparent width of a full moon.
