Potentially habitable worlds – Grok via Astrobiology.com This white paper introduces a framework for applying Assembly Theory (AT) to planetary atmospheres as a biosignature framework suitable for the Habitable Worlds

Miller’s Planet – Interstellar While the influence of supermassive black hole (SMBH) activity on habitability has garnered attention, the specific effects of active galactic nuclei (AGN) winds, particularly ultrafast outflows

The three-dimensional MHD stellar wind solution for Barnard’s Star. Color contours represent number density values, while selected magnetic field lines are also shown. The solid white circle marks the orbit
