ALMA reveals the chaotic teenage years of growing planets
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) as part of the Resolve exoKuiper belt Substructures (ARKS) survey captured 24 disks around young stars, showing complex rings, halos and asymmetries that indicate a turbulent, collision‑driven “teenage” phase of planet formation and offering new clues to how planetary systems evolve—including hints about our Solar System’s early history.
