The supernova number 63 of 2010 was discovered on 27 March, Cox and Puckett observers in the galaxy NGC 2357. As shown in the picture, the 2357 is a spiral galaxy presumably ready to sing, so before us as a thin object, well defined borders reminiscent of the drawing of a cigar.
is assumed that the supernova exploded in a peripheral area of \u200b\u200bthe galaxy, otherwise, in a location closer to the center can be significantly obscured by dust and interstellar gas of NGC 2357 to make very hard to detect. Evidence of this is the supernovae that have occurred in M82 galaxy also ready to chant, usually difficult to observe because of the material interposed between us and the phenomenon.
This is the strong wind and which encouraged the search for supernovas in galaxies that we face "in front" with the entire structure of arms to the eye and in the thickness of dust and gas is minimal and will not exercise an obstacle to detect this cataclysm in all its glory. But perhaps not as photogenic as this bj, although clearly detected, but this fascination with seeing that faint star embedded in the galaxy. In the Bishop supernovae page more and much better images.
The 2010 is of type IIp. Is supposed to be a very massive star that had come to obtain fusion energy of all elements, successively, from hydrogen to iron (through Helium, Carbon, Neon, Oxygen and Silicon) begins a catastrophic melting of the latter in the nucleus, giving rise to what we see as a star that for a days or weeks can get to shine as bright as its host galaxy, or harder yet.
