Astronomers using the Gemini North telescope have captured high-resolution images of the Pa 30 nebula, revealing previously unseen, bead-like structures within the supernova remnant.
Key facts
- •The Pa 30 nebula is the remnant of a supernova first recorded by Chinese and Japanese astronomers in 1181.
- •The new images were captured using the Gemini Multi-Object Spectrograph on the Gemini North telescope.
- •The filaments in the nebula contain pearl-like knots of gas that are roughly four light-days in diameter.
- •The central star of Pa 30 is considered a 'zombie star' because it survived the supernova explosion.
- •Researchers are studying the uniform, bead-like structures to better understand the process of stellar death.
Astronomers have released a highly detailed image of the Pa 30 nebula, the remnants of a supernova first documented by Chinese and Japanese observers in 1181. Captured by the Gemini North telescope in Hawaii, the new photograph reveals approximately 10 times more structures than previous observations. These features appear as filament-like strands composed of uniform, pearl-like knots of gas.
Discovery of Cosmic Pearls
The new imagery shows that the filaments within the nebula are not continuous, but rather consist of distinct, bead-like knots. According to a study published in The Astrophysical Journal, each of these knots measures about four light-days in diameter. Researchers noted that the planetary region of our solar system could fit inside a single knot approximately 10 times. The uniformity and alignment of these knots are unexpected, as scientists typically anticipate more irregular accumulations of material following a supernova.
The Zombie Star Phenomenon
Pa 30 is categorized as a 'zombie star' because the central star survived the thermonuclear explosion that typically destroys a star completely. While the exact mechanics of this survival remain unclear, researchers believe the newly observed structures may provide insight into how such detonations occur and why some stars persist afterward. The nebula is linked to historical records from 1181, when astronomers described a new star that remained visible for several months.
