Astronomers map exocomet belts around 74 stars, revealing insights into planetary system evolution.

Astronomers have mapped exocomet belts around 74 nearby stars using ALMA and SMA telescopes. These icy rocky belts, found at least 20% of the time, vary in structure from narrow rings to wide disks and contain pebbles that are remnants of exocomet collisions. The study, REASONS, also suggests undetectable planets may influence these belts, offering insights into planetary system evolution.
