Can Organic Molecules Survive a Supernova Explosion?— First Detection of Hot Cores in a Supernova Remnant —
July 10, 2026
Abstract
For the first time, astronomers have discovered stellar cocoons rich in complex organic molecules within a supernova remnant. A research team from Niigata University, Gifu University, RIKEN, and Kyoto University in Japan used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe the remnant of a massive star that exploded approximately 1,600 years ago. The team discovered warm, dense cocoons of molecular gas surrounding newborn stars, known as hot cores, marking the first detection of such objects within a supernova remnant. The discovery suggests that newborn stars can remain protected within their natal cocoons, allowing their rich molecular composition to survive even under intense supernova feedback. The findings were published in The Astrophysical Journal on July 1, 2026.
