Rare Metals Reservoir Found in Galaxy Cluster

Post by Christopher K. »

A huge amount of chromium and manganese has been found in the central portion of the Perseus galaxy cluster by the JAXA/NASA orbiting x-ray observatory Suzaku. Suzaku studied twenty percent of the cluster--about 1.4 million light-years across.

Chromium was discovered in 1797 by Vauquelin. On Earth it's steel-gray in color; it's used to harden steel and manufacture stainless steel. It gives glass an emerald-green color.

Manganese was first isolated in 1774 by Gahn. After being treated it can be ferromagnetic. It gives glass an amethyst color.

Suzaku found thirty million solar masses' worth of chromium in the area. It found eight million solar masses' worth of manganese.

The Perseus galaxy cluster is 225 million light-years away and has almost 200 galaxies.

Los Alamos National Laboratory used to have an extremely colorful and evocative online version of the Periodic Table. Alas, it is now more like a generic site with somewhat small print.
