The cooling effect of aerosols adds an uncertainty of almost one degree in climate models. Sulfate aerosols are one of the most impactful types. An analysis of several widely-used models now concludes that their predications on the creation of sulfate aerosols in the atmosphere differ almost as much as a factor of two. The PACE satellite will help to reveal which models are most accurate. Publication in Journal of Geophysical Research.

First map of outflows from nearby quasar I Zwicky 1
SRON astronomers have for the first time mapped the outflows from one of the closest quasars— I Zwicky 1. Quasars are bright cores of galaxies powered by the supermassive black hole in their center. The team has probed gas outflows in I Zwicky 1 to map its system of clouds being blown away at tens to thousands of kilometers per second. Publication in Astronomy & Astrophysics.
