An article published in the journal “The Astrophysical Journal” reports the observation of structures in protoplanetary disks that probably were left by newborn and perhaps still developing planets. A team of researchers led by Feng Long of the University of Beijing used the ALMA radio telescope to examine disks surrounding young stars in the Taurus star formation region discovering that of 32 protoplanetary disks 12 were divided into rings, a situation associated with planetary formation.
