This artist’s concept shows what the gas giant planet that orbits the star Alpha Centauri A could look like. In the popular Avatar movies, this star’s system is home to a glowing fantasyland called Pandora, the made-up moon of an imaginary Jupiter-like planet. It turns out that, in real life, a gas giant planet actually seems to be orbiting Alpha Centauri A, according to astronomers who peered at it with the James Webb Space Telescope. From what they can tell, though, it looks to have the right size and mass to be a gas giant. And while a gas giant planet seems an unlikely home for life, moons offer the possibility of solid ground, or even oceans.
