I recall reading an article about (I think) two massive supergiant stars in close orbit around each other, one or both of which are highly unstable. Located in the southern skies, briefly it/they brightened up at some point in the last century to become (excepting the Sun) the second brightest stellar object as viewed from Earth after Sirius. There were also fears raised at one time that their poles were orientated towards our solar system, which was considered by some to be potentially dangerous. That notion has now been discounted. Nonetheless, I'm unable to recall the star's name or which constellation it/they are located. Dorado? I do remember seeing some spectacular (radio telescope-based?) images of what looked like a cosmic inferno, but that's all. Any ideas as to what this double star might be called?
