Washington, March 20 : A team of scientists has confirmed the origin of supernovae as being produced from dying red supergiant stars.
The scientists are from the Dark Cosmology Centre at the Niels Bohr Institute, University of Copenhagen and from Queens University, Belfast.
A star is a large ball of hot gas and in its incredibly hot interior hydrogen atoms combine to form helium, which subsequently forms carbon, other heavier elements and finally iron.
When all the atoms in the centre have turned to iron the fuel is depleted and the star dies.
