This week, we looked at the swirling chaos around supermassive black holes, anthropogenic climate effects over the Atlantic ocean and the threats to koalas.
New research shows that the supermassive black hole at the center of a galaxy can have a direct impact on the chemical distribution of the host galaxy. This provides another piece of the puzzle for understanding how galaxies ...
