New Observations Reveal Clumpy, Knotted Gas Filaments in Ancient Supernova Remnant Pa 30

Researchers utilizing the Gemini North telescope, supported by the U.S. National Science Foundation, have uncovered new details in the nebula Pa 30, the remnant of a supernova observed over 800 years ago in 1181. Highly detailed observations show that the nebula's firework-like gas filaments are not smooth but are instead clumpy and knotted, providing new insights into the complex structures formed by supernova explosions.
