GoKawiilGemini North reveals fine filament structure in 1181 supernova remnant Pa 30
Astronomers using NOIRLab's Gemini North telescope have captured detailed new images of Pa 30, the debris field from a supernova recorded by Japanese, Chinese and Arab astronomers in 1181. The images, published in The Astrophysical Journal, resolve far more filaments of ionized sulfur and oxygen than previously seen, surrounding a surviving star at the remnant's center, located about 7,500 light-years from Earth.
GoKawiil's interpretation of the reporting above, not reported fact.
The remnant's unusual symmetry alongside its violent origin poses a puzzle for researchers studying how some stars survive their own explosions. Lead author Ilaria Caiazzo suggests Pa 30's proximity makes it an especially valuable test case for understanding rare supernova types, which could refine models of stellar death more broadly.
- Pa 30 is the remnant of a supernova observed in 1181 by astronomers in Japan, China and the Arab world.
- New Gemini North images show ten times more sulfur filaments than earlier observations.
- The remnant's symmetric structure around a surviving star presents an unusual case for astrophysicists.
