Compact Symmetric Objects (CSOs) harbor supermassive black holes that emit powerful jets traveling at near-light speeds in opposite directions. However, unlike their counterparts in other galaxies, these jets remain compact, not extending out to great distances as expected. For decades, scientists presumed that CSOs were youthful entities, with their jets destined to expand over time. New findings, published in three papers in The Astrophysical Journal, challenge this notion.
