Is a Cat’s Eye nebula a dying star?
Three thousand light-years away, the Cat’s Eye Nebula, a dying star throws off shells of glowing gas. This image from the Hubble Space Telescope reveals the nebula to be one of the most complex planetary nebulae known.
What does a nebula contain?
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.

Can you see the Cat’s Eye nebula with a telescope?
Unlike larger planetaries like the Helix Nebula, the Cat’s Eye is tiny, some 16″ across, and has a relatively high surface brightness which makes it easier to see in light-polluted skies. With a 4-inch or larger telescope at 30x to 40x, you’ll just be able to discern the nebula from the surrounding stars.
Why is it called Cat’s Eye nebula?
NGC 6543 was discovered by the German-born British astronomer William Herschel on February 15, 1786. Herschel compared the nebula’s appearance to that of the disk of an outer planet when seen through a small telescope, which is how planetary nebulae got their name.

Cat’s Eye Nebula/Distance to Earth
Is nebula and planetary nebula the same?
Planetary nebula, any of a class of bright nebulae that are expanding shells of luminous gas expelled by dying stars.
What are two special things that can be said about the Cat’s Eye nebula?
Inside NGC 6543 – nicknamed the “Cat’s Eye Nebula” – the Hubble has revealed delicate structures including concentric gas shells, jets of high-speed gas, and unusual shock-induced knots of gas… and thanks to Jukka’s “magic vision” we’re able to take a look into the Cat’s Eye as it might appear in dimension.
How is Crab Nebula made?
These wisps form along magnetic field lines in a gas of extremely energetic particles driven into space by the highly magnetized, rapidly rotating neutron star. The “guest star” they observed was actually a supernova explosion, which gave rise to the Crab Nebula, a six-light-year-wide remnant of the violent event.
Can you look into the Cat’s Eye Nebula?
Inside NGC 6543 – nicknamed the “Cat’s Eye Nebula” – the Hubble has revealed delicate structures including concentric gas shells, jets of high-speed gas, and unusual shock-induced knots of gas… and thanks to Jukka’s “magic vision” we’re able to take a look into the Cat’s Eye as it might appear in dimension. Step inside and let’s learn more…
When did William Herschel discover the Cat’s Eye Nebula?
Cat’s Eye Nebula. The Cat’s Eye Nebula or NGC 6543, is a relatively bright planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786.
Which is the easiest nebula to see from Earth?
Not much further down the list of accessible planetaries is the famous Cat’s Eye Nebula (NGC 6543). It’s one of the newest such nebulae, just a thousand years old, and one of the easiest to see because of its high surface brightness.
How many nebulae are there in our galaxy?
Most stars will eventually become planetary nebulae, if just for a few tens of thousands of years out of their billion-year life spans. About 3,000 planetary nebulae exist in our galaxy, and perhaps a hundred are visible to determined backyard stargazers with a small telescope.
