Astounding August Science Breakthroughs: Exoplanet Next Door, AI Milestone, Climate Alarms & More
NASA’s James Webb Space Telescope directly imaged a Saturn-mass exoplanet candidate orbiting Alpha Centauri A, about 1–2 AU from its star and 4 light-years from Earth. If confirmed, it would be the closest directly imaged exoplanet to its star, enabling detailed follow-up by the Roman Space Telescope.
