You can't make a Solar System without a whole lot of dust. And that's the problem. This dust has blocked astronomers views into some of the most fascinating parts of the cosmos. It shields the galactic core, enshrouds newly forming stars and their planets, and blocks our view to churning supermassive black holes, actively feeding in distant galaxies. But new telescopes and techniques are allowing astronomers to peer through this dust, and see these events like never before.
