Recent images from the NASA/ESA Hubble Space Telescope and the ESA’s Euclid mission showcase the intricate multi-shell structure of the fascinating planetary nebula NGC 6543, famously known as the Cat’s Eye Nebula.

The Cat’s Eye Nebula, located roughly 4,300 light-years away in the constellation Draco, has intrigued astronomers for decades due to its complex, multi-layered architecture.
“Planetary nebulae,” as they are called, derive their name from their round appearance in early telescopic observations; they are actually colossal gas clouds expelled from stars nearing the end of their life cycle,” the Hubble and ESA astronomers explained.
This insight was initially uncovered in 1864 using the Cat’s Eye Nebula itself. Studying its light spectrum allows scientists to identify individual molecules, a characteristic that differentiates planetary nebulae from stars and galaxies.
Near-infrared and visible-light imagery from the Euclid mission illustrates the arcs and filaments of the nebula’s luminous core, enveloped in a mist of vibrant gas debris that is retreating from the star.
“This ring was expelled from the star prior to the formation of the central nebula,” the astronomers noted.
“The entire nebula is prominently set against a backdrop brimming with distant galaxies, exemplifying how local astrophysical wonders and the farthest reaches of the universe coexist in today’s astronomical surveys.”

Through a wide-field lens, Hubble has captured stunning high-resolution visible-light images of the nebula’s swirling gas core.
The data reveals an intricate tapestry of features that appear almost surreal, including concentric shells, high-velocity gas jets, and dense knots shaped by impact interactions,” the researchers stated.
“These structures are believed to document the transient mass loss from the dying star at the nebula’s center, creating a cosmic ‘fossil record’ of its final evolution.”
“The combination of Hubble’s focused observations and Euclid’s deep-field data not only emphasizes the nebula’s delicate structure but also situates it in the broader cosmic landscape explored by both telescopes.”
“Together, these missions offer a rich, complementary view of NGC 6543, illuminating the subtle interplay between a star’s end-of-life processes and the vast universe that surrounds it.”
