A new exoplanet risk factor: active supermassive black holes

New research argues that active galactic nuclei can strip atmospheres and damage ozone far from a galaxy’s center, widening the map of what makes a world uninhabitable.

Key Takeaways

A new study examines how active supermassive black holes affect exoplanet habitability.
High-energy output from AGN can strip atmospheres and erode ozone at great distances.

Young Sun-Like Stars May Be Less Destructive to Planet Atmospheres Than Expected

New research suggests young solar-mass stars may dim and soften in X-rays earlier than previously thought, potentially easing some of the atmospheric stripping risk for nearby planets.

Key Takeaways

A new study suggests young solar-mass stars may soften and dim in X-rays earlier than expected.
The result could mean less atmospheric stripping for some orbiting planets.

Arid exoplanets may lose climate stability even inside habitable zones

New research argues that worlds with too little water may fail to sustain the carbonate-silicate cycle that helps keep Earth temperate, suggesting that some planets inside habitable zones could still drift toward Venus-l

Key Takeaways

Researchers argue that too little water can disrupt the climate-stabilizing carbon cycle on rocky planets.
The study says rainfall is critical to silicate weathering, which removes carbon from the atmosphere.
