First Discovery of a Binary Companion for a Type Ia Supernova
A team of astronomers led by The University of Texas at Austin’s Howie Marion has detected a flash of light from the companion to an exploding star. This is the first time astronomers have witnessed the impact of an exploding star on its neighbor. It provides the best evidence on the type of binary star system that leads to Type Ia supernovae.

I take it you realise that this says nothing about the unsolved problem of the origin of type 1a supernovae. It just says that the white dwarf that went supernova was part of a binary star system. Given that about 30% of all star systems are multiples this is not too surprising.
