SN 2005E explained
SN 2005E (aka 2005-1032) was a calcium-rich supernova first observed in January 2005 that scientists concluded was a new type of cosmic explosion.[1] The explosion originated in the galaxy NGC 1032, approximately 100 million light years away.[2] [3]
Location: (Epoch J2000)
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.[4]
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 supernovae.
