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 ...
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.

On the night of Oct. 5, 1923, Hubble pointed the 100-inch telescope toward M31, a blob of faint light then known as the Andromeda nebula. The human eye only collects up to 0.2 seconds of visual ...
The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding , most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [ 3 ]
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
