M82 Galaxy with Supernova, in Infrared by sjrankin on Flickr.

Via Flickr:
The supernova SN 2014J is seen in this image near its peak brightness in the first week of February 2014. It appears as a faint star to the lower right of the central region of its host galaxy M82.

The new supernova is of a particular kind known as a Type Ia. This type of supernova results in the complete destruction of a white dwarf star-the small, dense, aged remnant of a typical star like our Sun. Two scenarios are theorized to give rise to Type Ia supernovas: In a binary star system, a white dwarf gravitationally pulls in matter from its companion star, accruing mass until the white dwarf crosses a critical threshold and blows up. Alternatively, two white dwarfs in a binary system spiral inward toward each other and eventually explosively collide.
