An article published in the journal “The Astrophysical Journal Letters” reports the observation of what is interpreted as a circumplanetary disk in the system of the young star PDS 70. A team of researchers led by Andrea Isella of Rice University in Houston, Texas, used the ALMA radio telescope to detect the emissions of that disk that surrounds the exoplanet PDS 70 c and according to the astronomers is of the type that controls the formation of planets and of a system of moons such as those around the planet Jupiter.
