WASP-121b: Mapping Iron Clouds and Metal Rain on a Hot Jupiter - Video

Explore WASP-121b, an exoplanet 855 light-years away that defies planetary science. This ultra-hot Jupiter features dayside temperatures hot enough to vaporize metal and nightside conditions where liquid metal clouds form. Astonishingly, the rain on WASP-121b is composed of liquid rubies and sapphires, formed from condensing aluminum and other minerals. The planet's extreme proximity to its star creates supersonic winds and a unique atmospheric cycle, offering insights into planetary migration and the vast diversity of cosmic weather.
