Exoplanet WASP-69b has a cometlike tail – this unique feature is helping scientists like me learn more about how planets evolve
Located 163 light-years from Earth, a Jupiter-sized exoplanet named WASP-69b[1] offers astrophysicists a window into the dynamic processes that shape planets across the galaxy. The star it orbits is baking and stripping away the planet’s atmosphere, and that escaped atmosphere is being sculpted by the star into a vast, cometlike tail at least...
