"Uncovering Unforeseen Structures in Young Planetary Disks"

New observations with the Atacama Large Millimetre/submillimetre Array (ALMA) suggest that planet formation around young stars may begin much earlier than previously thought, challenging existing theories. High-resolution images from the CAMPOS survey reveal rings and gaps in Class 0 and Class 1 protoplanetary disks, indicating potential planet formation at very early stages. The presence of these structures suggests that the disks have calmed enough for planets to start forming within about 300,000 years into the life of the young stellar object. However, it remains uncertain whether these substructures are caused by planets or other instabilities, and further observations are needed to determine their nature.
