New Delhi: The calcium in our bones has a cosmic link, according to a new study. Astronomers have come across a new type of supernova, which they believe may be the chief source of calcium in the universe, including the Earth.
Even if two such supernovae occur every 100 years they would produce the high abundance of calcium seen in our galaxy, the Milky Way, and in all life on Earth, the scientists point out. "It’s a confusing, muddy situation. But we hope that, by finding more examples of this and other unusual supernovae and observing them in greater detail, we will get a better understanding of the physics that’s actually going on," the Scotsman quoted Prof Alex Filippenko, of the University of California at Berkeley, as saying. The findings of the study have been published in the journal Nature. ANI
