Summary:
- The Atacama Large Millimeter/submillimeter Array (ALMA) has observed a protoplanetary disk around the young star HD 163296, which provides insights into how planets form.
- The observations reveal a gap in the disk, which suggests the presence of a young, forming planet that is clearing a path through the disk material.
- This "missing link" between the formation of planets and the observable features of protoplanetary disks helps scientists better understand the early stages of planet formation.
