The parsec-scale radio jets that form around supermassive black holes are orthogonal to the (kiloparsec-scale) optical shape of the galaxies they’re hosted in, implying an evolutionary connection.

The differences between the estimated and measured organic matter abundances of asteroid Ryugu may result from variations in the superficial organic matter distribution, porosity of the asteroid’s surface or the observation geometries used in such studies.

The ASTRO 3D Centre of Excellence achieved 50% women personnel over a 5 yr time-frame by implementing a suite of evidence-based recruitment and retention initiatives. These initiatives changed how postdoctoral researchers were recruited and helped to develop a supportive and positive culture.

Our current cosmological observations cannot distinguish between a cosmological model with a fifth force acting on dark matter and one for which the laws of gravity are modified. Instead, a method using future gravitational redshift data is proposed.

Each uncontrolled rocket body in orbit poses a low casualty risk on reentry. But the cumulative risk is unacceptable and disproportionately borne by the Global South. Spacefaring states must stop exporting these risks and plan for safer reentries.
