Located 163 light-years from Earth, a Jupiter-sized exoplanet named WASP-69b 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 350,000 miles long.
I’m an astrophysicist. My research team published a paper in the Astrophysical Journal describing how and why WASP-69b’s tail formed, and what its formation can illuminate about the other types of planets astronomers tend to detect outside of our solar system.
