We welcome Dr. Marcel Pawlowski of the Leibniz Institute for Astrophysics Potsdam. He is the Leibniz Junior Research Group leader, and in Science Magazine, which is the peer reviewed top-of-the-pile, we read that Marcel and his colleagues have solved one problem and created another in the cosmos.
And that's a good thing.
When astronomy creates problems, it means we're learning. And the problem goes this way: there were once too few dwarf galaxies for the standard model. Now, thanks to Marcel, there are too many.
What does it mean to be a dwarf galaxy? And what does it mean that we were worried that there were too few?
