HONG KONG: A large part of the iron found on the Earth is chiefly attributable to something which takes place in the sky!
What happens is a Supernova; a gigantic bright explosion that occurs when a certain star dies, outshining entire galaxies of stars. Bright Supernovas are rarely visible to the naked eye; only once every few hundred years. However, modern tools and telescopes have made this spotting easier and regular. Particularly Type Ia supernova are used by astronomers to study cosmic mysteries.
The researchers, Dr Danny Tsebrenko and Dr Noam Soaker from the Department of Physics at the Israel Institute of Technology have used computer simulations, published in Arxiv, to work out what happens when a Type 1a supernova takes place.
The scientists found that giant clouds of iron are ejected by white dwarf stars after they undergo supernova. These clouds, referred to as ‘iron bullets’ are extremely massive and contains iron, several times the mass of Jupiter, which eventually makes its way to the earth.
Another study led by Rob Olling at the University of Maryland, using the Kepler space telescope found three Type Ia supernovae but no signs of companion stars. The study asserts that the companion stars must be very small white dwarfs themselves and the explosion is triggered when two white dwarfs spiral into each other and collide.
