Learn more about WASP-121b, the exoplanet so hot it could vaporize iron.

WASP-121b is an ultra-hot giant planet that orbits its host star at a distance of only about twice the star's diameter, completing one orbit in approximately 30.5 hours.

WASP-121b is like nothing in the solar system, raining liquid metal and being puffy like a marshmallow. The origins of these "toasted marshmallow" planets could be more complicated than thought.

But because WASP-121b is an ultra-hot Jupiter with extreme temperatures, both materials are vaporized into the atmosphere and are detectable with the high spectral resolution of IGRINS.

Tylos (or WASP-121b) is a gaseous, giant exoplanet located some 900 light-years away in the constellation Puppis. Using the ESPRESSO instrument on ESO’s Very Large Telescope (VLT), scientists ...

WASP-121b is an exoplanet (meaning a world beyond our solar system) called a "hot Jupiter" because it's a gaseous giant that orbits close to its searing star.Crucially, the planet is tidally ...

The distant world WASP-121b is so hot that it hosts metallic clouds and rains gems.. Astronomers discovered the gas giant planet — dubbed a "hot Jupiter" — in 2016, but have continued to ...
