The New Horizons spacecraft performed a flyby of Pluto and its system in July 2015, providing more than 50 Gb of high-resolution images and data that transformed our view and understanding of the dwarf planet. This Review summarizes its main discoveries.
The material surrounding accreting supermassive black holes connects them with their hosts. From studies in the infrared and X-rays, the structure of this material is found to be complex, clumpy and dynamic.
Radio astronomy will be transformed by future surveys that will study tens of millions of radio sources, providing new insights into a broad range of open questions in astronomy. This transformation, and the lead-up to it, is summarized in this Review.
Quantifying the effect of active galactic nuclei (AGNs) on their hosts requires knowledge of their life cycle. This review on AGN archaeology summarizes the main recent findings regarding the AGN life cycle from optical and radio observations.
Total solar eclipses are a unique opportunity to study the lower solar corona where the solar wind originates. This review presents the recent advancements in coronal science from eclipses and the scientific and outreach plans for this year's totality.
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.
