Feedback from actively accreting supermassive black holes is thought to be important in the evolution of galaxies. Theoretical and observational results are reviewed with regard to the impact of this feedback on star formation in galaxies.
Planetary nebulae, traditionally seen as an endpoint of single stars, exhibit a variety of morphologies that cannot be explained in a single-star scenario. It is becoming clearer that perhaps even the majority of planetary nebulae result from binary interactions.
The acceptance of dark matter came slowly despite its abundance. Jaco de Swart and colleagues reconstruct the history of how dark matter brought astronomers to cosmology in their Review Article, which is part of the Insight on dark matter.
This Review gives an overview of some pivotal open questions on planetary formation and evolution, with water as the underlying common theme, and how the planetary and exoplanetary communities can help each other in addressing them.
