==Research and Conclusions==
On May 19, 2010, a team of astronomers released a report on the discoveries made in their research of SN 2005E.  The articles were published in the British journal ''[[Nature (journal)|Nature]]''.<ref>{{cite journal |doi=10.1038/nature09056 |title=A faint type of supernova from a white dwarf with a helium-rich companion |year=2010 |last1=Perets |first1=H.

The researchers have determined that the blast emitted a large amount of [[calcium]] and [[titanium]], which is evidence of a nuclear reaction involving [[helium]], instead of the [[carbon]] and [[oxygen]] that is characteristic of [[Type Ia supernova]]e.
