And it rains liquid iron and gems on these exoplanets.
yet within the atmosphere of two blisteringly hot exoplanets where it rains liquid iron and gems from the skies. As if that was not enough, researchers have now detected barium in their upper atmosphere, making them even more unusual than previously thought.
The sizzling temperature of the exoplanets gives these worlds their unusual characteristics, like how WASP-76 b is thought to experience showers of iron from the sky, while WASP-121b experience metal clouds and flurries of gems.in the upper atmosphere of these exoplanets. The element is 2.5 times heavier than iron.
"Given the high gravity of the planets, we would expect heavy elements like barium to quickly fall into the lower layers of the atmosphere," said study coauthor Olivier Demangeon, a postdoctoral researcher at the University of Porto and the Institute of Astrophysics and Space Sciences in Portugal, in a statement.could be far more exotic than previously thought.
