Astrophysicists Discover Comet-Like Tail on Exoplanet WASP-69 b

Astrophysicists have discovered that the exoplanet WASP-69 b possesses a comet-like tail of gas extending 563,000 kilometers, revealing significant atmospheric loss due to photoevaporation. This hot Jupiter, located 160 light-years away, loses around 200,000 tons of gas per second, primarily hydrogen and helium, shaped by stellar winds. This groundbreaking research enhances our understanding of exoplanetary atmospheres and their dynamics, contributing to the field of astrophysics.
