Pa 30

No, this is not a firework display. This is Pa 30 — the likely remnant of the historic supernova witnessed in the year 1181, now captured here in unprecedented detail by the Gemini North telescope, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. This image was captured with the Gemini Multi-Object Spectrograph (GMOS), and it shows that the remnant’s unmistakable firework-shaped ejecta take on a cascading knot-like structure.
