A supermassive black hole has been found in an ultracompact dwarf galaxy – the smallest galaxy known to contain such a massive black hole. This finding, published today in Nature, suggests that supermassive…
Over the last few years we’ve been studying the orbits of dwarf galaxies and we expecting to find them buzzing at random around large galaxies. But looking out into the universe, we see some dwarfs undertaking…
