Astronomers challenge established models with new studies AI illustrationhow this picture was made

LONDON, Oct 15, 2026 - Two independent astronomy studies were published on 15 October 2026, each contradicting long held working models in the field. One paper, appearing in Nature Astronomy, identifies a clear bimodality in system masses that divides all known multi-planet architectures into two distinct families ^[1]. A second study released the same day concludes that hypernovae, previously classified as the most powerful stellar explosions in the universe, may never have actually occurred ^[2]. Space Nugget. Multi-planet systems are groups of worlds orbiting a single star, outside of our own Solar System.
