Story summary

Astronomers captured images of 24 debris disks around infant stars with the Atacama Large Millimeter/submillimeter Array (ALMA) as part of the ARKS survey.
The observations show the chaotic 'teenage years' of planetary systems, with disrupted orbits and major impacts.
Findings reveal diverse disk structures, including multi-ringed belts and asymmetries, indicating a dynamic formation history.
The ARKS survey involves about 60 scientists from various institutions to advance planetary evolution knowledge.
