Astronomers have directly observed two worlds beyond our solar system shedding their outer layers into space for the first time.

The first "disintegrating" exoplanet is a Neptune -size rocky world called K2-22b , which zips around its star so closely that it completes an orbit in just nine hours .

Another planet, BD+054868Ab, is the closest evaporating planet to Earth discovered so far.

The findings offer an unprecedented glimpse into the interiors of planets.
