Summary:
- The Atacama Large Millimeter/submillimeter Array (ALMA) has provided unprecedented observations of planet-forming disks around young stars, revealing new insights into how planets form.
- The detailed images from ALMA show that these disks are not uniform, but have complex structures, including gaps, rings, and spirals. These features suggest that planets are already starting to form within the disk, even at very early stages.
- The new models developed based on ALMA's observations suggest that the interactions between the disk and newly forming planets play a crucial role in shaping the final architecture of planetary systems.
