A '''Type Ia supernova''' (read: "type one-A") is a type of [[supernova]] that occurs in [[binary system]]s (two [[star]]s orbiting one another) in which one of the stars is a [[white dwarf]]. The other star can be anything from a [[giant star]] to an even smaller white dwarf.<ref>[https://web.archive.org/web/20190624065845/http://hubblesite.org/hubble_discoveries/dark_energy/de-type_ia_supernovae.php HubbleSite - Dark Energy - Type Ia Supernovae]</ref>
