Supernova in the constellation Cetus
SN 2005E (aka 2005-1032) was acalcium-rich supernova first observed in January 2005 that scientists concluded was a new type of cosmic explosion.[1] The explosion originated in the galaxyNGC 1032, approximately 100 million light years away.[2][3]
Location:02h 39m 14.34s +01° 05′ 55.0″ (Epoch J2000)
Research and Conclusions
[edit]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 journalNature.[4]
The researchers have determined that the blast emitted a large amount ofcalcium andtitanium, which is evidence of a nuclear reaction involvinghelium, instead of thecarbon andoxygen that is characteristic ofType Ia supernovae.
