Space.com: Milky Way Fortified with Calcium

"Milky Way Fortified with Calcium."

This clever headline got a laugh out of me this morning. No, it's not the Milky Way candy bar, it's the Milky Way galaxy. And it was found to have 50 percent more of the element Calcium than previously thought.

So what's the impact of such a finding? Time to revisit some cosmological models. From the site:

“If certain types of supernovae indeed produce more calcium, then this means that there must be more calcium in the universe compared to the predictions from the supernova models, then this is not only true for clusters, but also for our solar system and everything that lives in it, because we are mostly made of the same supernova products.”
