Summary:

- The article discusses the discovery of a new type of star called a "Thorne-Żytkow object" (TŻO), a rare type of hybrid star that contains a neutron star at its core.
- TŻOs are believed to form when a neutron star and a red supergiant star merge, creating a unique stellar object with properties of both types of stars.
- The discovery of this TŻO candidate, named M101 ULX-1, provides important insights into the formation and evolution of these rare stellar hybrids, which could help scientists better understand the complex processes that shape the universe.
