December 12, 2009--The product of three billion star explosions, the largest known grouping of rare metals in the universe—in this case chromium and manganese—have been detected via the x-ray radiation of the hundred-million-degree Fahrenheit gas in which the metals reside, according to findings from the orbiting Suzaku x-ray telescope.

The chromium in this intergalactic cloud in the Perseus galaxy cluster (pictured) is more massive than 30 million suns, Suzaku scientists said.

"By measuring metal abundances, we can understand the chemical history of stars in galaxies, such as the numbers and types of stars that formed and exploded in the past," project leader Takayuki Tamura, an astrophysicist at the Japan Aerospace Exploration Agency, said in a statement.
