The utility of such explosions is based on two empirical observations. WebSince type 1a supernovae are so luminous, they can be used to measure the distance to far more distant objects than can cepheid variable stars. 6700 67 50000 500 Cepheid Variable stars and Type 1a supernovae are both standard candles - objects of known luminosity used to estimate interstellar distances.

WebThe large amounts of Ni 56 that are observed in these supernovae decay to Co56 and then to iron. Type Ia supernovae are the most efficient known production sites of iron. A significant amount of the iron in the universe, including a large fraction of Earth’s mass and the iron in your blood, was produced in such supernovae.

And first they're empirically classified on the basis of their spectra, whether or not they have lines of hydrogen in their spectrum. Hydrogen being by far the most common element, you expect that to be present, but Type I supernovae have no hydrogen.
