no word on how this would effect that earth-like planet they discovered in another galaxy a couple of weeks ago?
That earth like, kinda sorta, planet is not in another galaxy, it is actually *very* near the earth. Around 20 light years. There's only about 131 stellar objects within 20 light years of earth.
Compared to the distances to the distant galaxy containing this super-supernovae or even the distant to the similiar star in our Galaxy, it's effectively next door.. or actually more like another apartment in the same small apartment building.
