An international team led by researchers from the University of Cologne has solved the mystery of an extraordinary phenomenon known as the “Diamond Ring” in the star-forming region Cygnus X, a huge, ring-shaped structure made of gas and dust that resembles a glowing diamond ring. In similar structures, the formations are not flat but spherical in shape. How this special shape came about was previously unknown.
