A team of researchers at the International Center for Relativistic Astrophysics has found evidence that suggests Sagittarius A* is not a massive black hole but is instead a mass of dark matter. In their paper published in ...
There are a few places in the universe that defy comprehension. And supernovae have got to be the most extreme places you can imagine. We're talking about a star with potentially dozens of times the size and mass of our own ...
