Supernova (exploding stars)  rich in calcium!

Scientists say it may explain why there's so much of it in the universe, and in us.

"The total amount [of calcium] we see [in the universe] is quite high," Filippenko said, "more than can be explained with conventional supernovae. This new class could explain the large amount of calcium."

Nearly half of the material expelled from SN 2005E was calcium — five to 10 times as much, in terms of mass, than calcium produced by typical supernovae of any variety, according to the paper co-written by Filippenko. The researchers said that it would take only one or two of these calcium-rich supernovae every 100 years to generate all the calcium present in life on earth.
