In what has been called a supernova factory, the galaxy NGC 2770 has been captured by the Gemini Observatory in a spectacular new image that shows at least three recent supernovae locations including SN 2008D which was announced today to be the first X-ray detection of a supernovae prior to becoming visible across the spectrum.
The high-resolution color composite image also shows a suspected companion galaxy that is thought to be interacting with the host galaxy. It is suspected that these interactions sparked the formation of massive stars and the resulting fury of supernovae activity in this galaxy.
NGC 2770 is a spiral galaxy located at a distance of about 88 million light years away in the direction of Lynx a constellation in the Northern hemisphere.
