Summary. The Cat's Eye Nebula is mainly located in the constellation Draco, about 3,000 light-years away from Earth, and looks very similar to a cat's eye, so it is called the Cat's Eye Nebula. According to the footage taken by the Hubble Space Telescope, it can be seen that this nebula has a variety of shapes and structures, including knots, jet columns, and so on.
Hello dear, the cat's eye nebula is called the cat's eye nebula because it looks like a cat's eye. It was first discovered by William Herschel on February 15, 1786, and is one of the most complex nebulae known.
The Cat's Eye Nebula is mainly located in the constellation Draconia, about 3,000 light years away from the Earth, and looks very similar to the cat's eyes, so it is called the Cat's Eye Nebula.

The Cat's Eye Nebula is a planetary nebula in the constellation Draconia, named for its resemblance to a cat's eye. Images taken from the Hubble Space Telescope show that the Cat's Eye Nebula comes in a variety of shapes, such as knots, jets, and arcs. The Cat's Eye Nebula is mainly located in the constellation Draco, about 3,000 light-years from Earth.
It looks a lot like a cat's eye, so it's called a cat's eye nebula. According to the Hubble Space Telescope, this nebula has a wide variety of shapes and structures, including knots, jets, and more.
What is the existence of the Cat's Eye Nebula?
The cat's eye nebula is called the cat's eye nebula because it looks like a cat's eye. It is a planetary nebula with many complex structures. It was first discovered by William Herschel on February 15, 1786, and is one of the most complex nebulae known to date.
In 1864, British astronomers also studied it and carried out spectral analysis. This is also the first time that spectral analysis techniques have been applied to nebulae, which is a great innovation and has great significance for modern science.
In modern science, many studies have succeeded in solving the mystery of the cat's eye nebula. It has been suggested that the complexity of this nebula is mainly due to the eruptive material of the main star in this system. However, there is no evidence that the ** stars of this nebula have companion stars.
An important feature of the Cat's Eye Nebula
This nebula is really cat's eye, and it's pretty good. As one of the ten most beautiful nebulae in the universe, it lives up to its name. This is a classic planetary nebula.
Although it looks gorgeous and beautiful, it actually has a rather short lifespan. Like the previous Butterfly Nebula and the Blink Nebula, they both have a very short lifespan.
In fact, this nebula is in its dying phase, and it constantly throws outer layers of matter into the universe, eventually forming a simple and beautiful shape. The internal structure is more complex, but the specific formation is not very well understood.
Conclusion: This beautiful nebula, located about 3,000 light-years from Earth, still shows its special beauty. Although it has a fairly short lifespan, it is quite interesting for people.

The cat's eye cloud is 3000 light-years away from Earth. The Cat's Eye Nebula is a planetary-shaped nebula that is particularly shaped like a cat's eye. The structure is very complex and was discovered in 1786.
-
It is about 3,000 light-years away from Earth; The cat's eye nebula is a space nebula that looks like a cat's eye; Observed under a telescope, it is very beautiful, but its composition is quite complex.
-
The distance from Earth is about 3,000 light-years. The Cat's Eye Nebula is mainly in the constellation Draconus, and it looks very similar to the Cat's Eye.
-
They are about 3,000 light-years away from Earth; They are also known as cat's eye nebulae mainly because they are shaped specifically like cat's eyes.
-
They are formed by the gas released or ** out of the star in their later years, which belongs to a typical nebula, when the star forms a white dwarf, it will spray a large amount of gas outward through phenomena such as helium flash, forming a planetary nebula, the most common are cat's eye nebula and spiral nebula, they are planetary nebulae.

There are many strange nebulae in the universe, such as the world-famous Pillar of Creation, or the Eye of God, which we introduced before, and this episode also introduces you to a very strange nebula.

The Cat's Eye Nebula is a planetary nebula located in the constellation Draconia. What makes this nebula special is that its structure is one of the most complex of almost all recorded nebulae. The Cat's Eye Nebula has various shapes such as knots, spray columns, and arcs.
This nebula was first discovered on February 15, 1786 by William Herschel of England. In 1864, the British amateur astronomer William Heggins made a spectral analysis of the cat's eye nebula, which was also the first time that the spectral analysis technique was used on a nebula.

The Cat's Eye Nebula is a planetary nebula located in the constellation Draco on February 1, 1786. Herschel was first discovered by William Herschel of England on February 1, 1786, and the structure is the most complex.

This nebula is one of the most widely studied nebulae, with an apparent magnitude of + and a high surface luminosity. Its right ascension and declination are +66°38 respectively', whose high declination represents the Northern Hemisphere, which is more visible to observers. Many large telescopes are located in the Northern Hemisphere, and since the nebula is located close to the north of the Yellow Pole, it should not be difficult to find in good weather if you look near the Yellow Pole.
In terms of diameter, the brighter inner nebula is about 20 arc seconds in diameter, and its dilated nebula halo material is about 386 arc seconds (arc minutes) in diameter. Its nebula halo material was ejected by the original star when it evolved into a red giant.
According to the observations, the density of the main nebula is about 5000 particles per cubic centimeter and the temperature is about 8000 k, and the outer nebula halo is even hotter at 15,000 k, while the density is lower than that of the interior.
The nebula** has an O-type (blue) star with a temperature of about 80,000 K, a luminosity of about 10,000 times that of the Sun, and a radius of times that of the Sun. According to spectroscopic analysis, due to the influence of stellar winds, the mass of ** stars is constantly losing at a rate of 20 megatons per second, which is equivalent to the mass of the sun every year, and the wind speed of stellar winds is 1900 kilometers per second. According to the calculations, the mass of the star is about the same as that of the Sun, about one solar mass, and the mass of the star before evolution is estimated to be about five times that of the Sun.
It's dark circles, which are caused by lack of sleep.
Not why, because he lost the battle with the Yellow Emperor, the so-called loser Kou. Of course, there are some places, such as his descendants, who do not consider him an evil god. He is also our great ancestor. You can refer to Wang Dayou's findings.
Quite simply, is killing good or evil? If it is evil, is it good or evil that you defend your family and kill the invaders? The parents of the invader, you are evil, and you are good to your own people.
