Our ESA/Hubble Picture of the Month features one cosmic eye 👁️ spied by two observatories! The Cat’s Eye Nebula (NGC 6543) is one of the most visually intricate remnants of a dying star. In 1995, Hubble revealed structures in it that helped us understand how planetary nebulae

Two images of a planetary nebula in space. The image to the left, labelled “Euclid & Hubble”, shows the whole nebula and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula and this region is the image to the right, labelled “Hubble”. It shows the multi-layered bubbles, pointed jets and circular shells of gas that make up the nebula, as well as the central star, in greater detail.
