NASA’s Astronomy Picture of the Day for October 7, 2026 shows Nebula Pa 30, imaged with the Gemini North Telescope in Hawai‘i. Pa 30 is the likely remnant of a supernova. Astronomers believe that explosion is the “guest star” that Chinese, Japanese, and Arabic observers recorded in 1181. The link is probable, not proven, and the cause of the explosion is still debated.
What is Pa 30?
Pa 30 is a nebula, a cloud of gas thrown off by a stellar explosion. NASA describes it as likely the remnant of an old supernova. The Gemini North image shows a hot, mysterious star at the center. Around it, long filaments of gas spread outward like spokes.
Is Pa 30 the remnant of the supernova seen in 1181?
Probably. According to NASA, separate records from Chinese, Japanese, and Arabic astronomers describe a guest star that appeared in 1181 and stayed visible for 185 days. NASA says this guest star is believed to be the same event that produced Pa 30. The word “believed” matters here. Medieval sky records do not give exact coordinates by modern standards, so the match rests on interpretation and supporting evidence, not on a signed confirmation.

What are the filaments and knots in the image?
The most striking feature is the pattern of radial filaments. NASA’s explanation says: “The mysterious central star in the image is extremely hot and produces a strong wind, possibly forming the radial filaments.” The wording is tentative. The wind is a candidate shaping mechanism, not an established one.
Along the filaments are pearl-like knots. NASA gives their diameter as 4 light-days. That is the distance light travels in four days, a tiny span next to a light-year but still enormous by everyday standards.

What caused the Pa 30 supernova?
NASA calls the event an unusual Type Iax supernova. The proposed cause is a merger of two white dwarfs, which are the dense remnants of Sun-like stars. NASA also says plainly that astronomers do not know exactly what happened.

NASA’s earlier April 3, 2024 APOD on Pa 30 described the same Type Iax and merger model. It also described the central blue object as a hypothesized surviving white dwarf, nicknamed a “zombie star.” That description is a hypothesis too.

What does new research add?
A 2026 preprint on the newly resolved knots reports two findings:
- The measured center of the nebula is consistent with the position of the central star. In that analysis, the study derives a 3-sigma upper limit of less than 14 km/s on a transverse kick to the star.
- The clumpy substructure is a new observational constraint on models of the filamentary ejecta.
This is a preprint, so it has not necessarily completed peer review. Its kick limit is model-dependent. It narrows the possibilities but does not prove how the star exploded.
