A massive gas giant orbiting a star about 855 light-years from Earth, WASP-121b may have metal clouds and rain made of liquid gems, according to new research.

A study showing how water atmospherically cycles between the planet's two sides published Monday in the journal Nature Astronomy.

The planet, first discovered in 2015, is considered to be an ultrahot Jupiter-like planet because it's hotter and has a greater mass and diameter than the largest planet in our solar system.

Since then, researchers have made discoveries that show WASP-121b only gets stranger the more they learn.
