Story summary

University of Cologne researchers identified the Diamond Ring's origin, a structure 4,500 light-years away in Cygnus, illustrating how massive stars influence surroundings.
The Diamond Ring spans about 20 light-years and includes a ring-shaped gas bubble and a clump of star-forming gas.
The ring is roughly 425,000 years old, far younger than previously thought.
Findings were published in Astronomy and Astrophysics using NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA).
