Summary:
- Astronomers have discovered a "pinwheel" star system called Wolf-Rayet 104, located about 8,000 light-years from Earth.
- This system consists of two massive stars orbiting each other, with the larger star shedding material in a spiral pattern as it rotates.
- The unique spiral shape is caused by the interaction between the two stars and the material being ejected, providing insights into the late stages of massive star evolution.
