While the bubble has generally been linked to the Cygnus X star-forming region, the new study argues that a microquasar more naturally explains its highest-energy emission. The results were published in a paper in The Astrophysical Journal Letters on July 21.","category":"Science","image":null,"lang":"en","publishedAt":"2026-08-14T18:20:07+00:00","createdAt":"2026-08-14T18:30:13.063416+00:00"}}
