A super-nova remnant in Andromeda galaxy

Gr@v member Valério Ribeiro was part of an international team of researchers studying thermonuclear eruptions in the Andromeda galaxy. The team published, in Nature magazine, the discovery of a super-nova remnant which is bigger than most supernova remnants. They found that the super-nova remnant was the consequence of yearly repeated eruptions over millions of years. Few of these systems are known in the galaxy due to the fact that we suffer from dust obscuration. However, the near future is bright for these of systems when the Square Kilometre Array, since radio wavelengths are transparent to dust in the interstellar medium, comes online with the capability of discovering all novae in our Galaxy. As part of the Springer Nature Content Sharing Initiative, the paper is available here.
