While it's known that Type 1a supernovae form from collapsing white dwarfs — the densest forms of matter after black holes and neutron stars — their formation theories come in two flavors: the single degenerate scenario in which a normal star is consumed by a white dwarf; and the double degenerate scenario in which two white dwarfs merge.

After the supernova, all that remains of the once magnificent star is a black hole or neutron star and a turbulent cloud of newly formed heavy elements.

In 2003, astronomers announced that they had discovered that iron from supernovae of the first stars (possibly from Type Ia supernovae involving white dwarfs) indicate that «massive chemically enriched galaxies formed» within one billion years after the Big Bang, and so the first stars may have preceded the birth of supermassive black holes (more from Astronomy Picture of the Day, ESA, and Freudling et al, 2003).
