- Astrobiologists theorise that low-oxygen planets would be unlikely to produce advanced civilisations, as the discovery of fire requires easy access to open-air combustion, which is only possible when oxygen partial pressure is above 18%. https://astrobiology.com/2023/08/the-oxygen-bottleneck-for-technospheres.html 149 comments space

- An exploded star can pose more risks to nearby planets than previously thought, according to a new study. This newly identified threat involves a phase of intense X-rays that can damage the atmospheres of planets up to 160 light-years away. https://astrobiology.com/2023/04/new-stellar-danger-to-exoplanets-identified-by-chandra-x-ray-observatory.html 24 comments science

- Researchers discover a network of fractures in Gale Crater filled with Opal, a water-rich mineraloid. This water-rich subsurface network would have been shielded from modern harsh surface conditions, allowing for a potentially habitable environment on Mars in a more recent era. https://astrobiology.com/2023/01/mars-curiosity-rover-discovers-water-rich-fracture-halos-in-gale-crater.html 11 comments science
