The inset panel is a pair of Hubble Space Telescope images of the spiral galaxy NGC 1309 that were taken before and after the appearance of Supernova 2012Z, in the outskirts of the galaxy. The white X-shaped feature at the top of the image of the galaxy marks the location of the supernova.
The inset panel from 2013 shows the supernova; archival Hubble data from 2005 and 2006 show the progenitor system for the supernova, thought to be a binary system containing a helium star transferring material to a white dwarf that exploded.
The stellar blast is a member of a unique class of supernova called Type Iax. These supernovae are less energetic, and hence fainter, on average, than their well-known cousins, Type Ia supernovae, which also originate from exploding white dwarfs in binary systems.

| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the ACS/WFC and WFC3/UVIS instruments. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image as follows: Image of NGC 1309 and 2005-2006 inset image: Blue: F435W (B) Green: F555W (V) Red: F814W (I) 2013 inset image: Blue: F555W (V) Green: F625W (R) Red: F814W (I) |
