Astronomers have for the first time spotted what appears to be a moon-forming ring of matter around a young exoplanet, and described their findings in a paper published on Thursday.
Orbiting a star 400 light-years away, PDS 70c is an otherworldly Jupiter-like gas giant that is particularly interesting to planet watchers. Unlike most other confirmed exoplanets, PDS 70c and its neighbor PDS 70b are not yet fully grown. So much so, when they were discovered in 2018 and 2019 respectively, it was the first time researchers were able to directly image a protoplanet.
