WASP-121 b is a sizzling hot exoplanet orbiting the star WASP-121, discovered back in 2016 using the clever transit method with the SuperWASP facility. This planet is a true cosmic furnace, so close to its star that it's tidally locked, meaning one side is in eternal daylight while the other basks in endless night. Its atmosphere is so hot and puffed up that it’s actually spilling over the edge, making scientists excited about studying its extreme weather and chemistry. Even though it’s far beyond our solar system, WASP-121 b offers a fascinating peek into the wild extremes planets can experience, showing just how diverse and surprising the universe is!
