Astronomers using the Gemini North telescope in Hawaii have produced the most detailed image yet of the Pa 30 nebula, the remnant of a supernova that was observed from Earth in 1181. The new image, described in The Astrophysical Journal, shows roughly ten times more structure than earlier views. Instead of continuous filaments, the ejecta appear as a series of bead-like knots of gas, each about four light-days in diameter.
These 'cosmic pearls' are strikingly uniform in size, which surprised researchers. In a supernova aftermath, one would expect irregular clumps, but the knots are aligned along filaments like beads on a string. The central star is also unusual: it is a 'zombie star' that survived the explosion, a phenomenon not fully understood. The new details may help astronomers reconstruct how such detonations happen and how a star can partially survive.
