The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins , demonstrating that planetary nebulae were gaseous ...
The Cat's Eye Nebula is one of the most intricate and complex planetary nebulae known. This Hubble Space Telescope image reveals a mass of twists and knots of material in the nebula's inner region. The origin of this structure is not yet well understood by astronomers

Messier 94 (also known as NGC 4736, Cat's Eye Galaxy, Crocodile Eye Galaxy, or Croc's Eye Galaxy [7] [8]) is a spiral galaxy in the mid-northern constellation Canes Venatici. It was discovered by Pierre Méchain in 1781, [ 9 ] and catalogued by Charles Messier two days later.
The nebula contains one of the most active star formation regions known, with an open cluster of thousands of stars being formed within it. 9 July 2005 . 10 July 2005 . File:NGC 6543 expansion.gif This image shows the expansion over a period of three years of the planetary nebula NGC 6543, the Cat's Eye Nebula.
NASA’s Hubble Space Telescope recently captured a breathtaking image of the spiral galaxy NGC 2566. Astronomers use detailed Hubble images to study star clusters and active star-forming regions.
NASA’s James Webb Space Telescope and Hubble Space Telescope captured a pair of spiral galaxies some 114 million light-years from Earth. The smaller galaxy on the left, known as IC 2163, passed ...
It is 9th magnitude and was named for its appearance in the Hubble Space Telescope, though it appears as a fuzzy blue-green disk in an amateur telescope. [1] NGC 6543 has a very complex shape due to gravitational interactions between the components of the multiple star at its center, the progenitor of the nebula approximately 1,000 years ago. [6]
