Direct imaging of extra solar planets. The cat dynamicist has the details. (because, linking, I’ve heard, is good.) Fomalhaut b, a nice name.
When I was on the road to becoming an astrophysicist, as a young grad student, I remember thinking how cool it would be to join the planet hunters. I mean being able to say that in your research you “discovered a planet” well how cool would that be. Alas I caught the quantum bug and so all those days spent studying the interstellar tedium are now lost, like tears in the rain.
