Astronomers using the James Webb Space Telescope believe they may have found a Saturn-sized planet orbiting Alpha Centauri A, one of the closest stars to Earth. The world, temporarily glimpsed in 2024, vanished from later Webb observations, sparking simulations to explain its disappearance. If real, it sits within the stars habitable zone, although as a gas giant it cannot support life directly. Still, its moons could. Confirmation would mark the closest planet ever directly imaged around a Sun-like star.
