A stellar nebula, often referred to as a primordial or star-forming nebula, is a vast cloud of gas and dust where new stars are born. In contrast, a planetary nebula is formed from the outer layers of a dying star, typically a medium-sized star, that have been expelled into space after the star has exhausted its nuclear fuel and shed its outer envelope. While stellar nebulae are associated with the birth of stars, planetary nebulae signify the end stages of a star's lifecycle.

What is the significance of the eskimo nebula?
The Eskimo Nebula, also known as NGC 2392, is a planetary nebula located in the constellation Gemini. It is significant because its distinctive shape resembles a face surrounded by a parka hood, giving rise to its popular name. The Eskimo Nebula is of interest to astronomers for studying the late stages of stellar evolution and the creation of planetary nebulae.
What is a star called that a star left at the core of a planetary nebula?
The remnant star left at the core of a planetary nebula is called a white dwarf. After a star like the Sun exhausts its nuclear fuel, it expels its outer layers, forming a planetary nebula, while the hot core remains as a white dwarf. This stellar remnant is primarily composed of carbon and oxygen and gradually cools and dims over time.
What is an example of a planetary nebula?
The Cats's Eye Nebula is a perfect example of a planetary nebula. See related link for a pictorial.
How much does a planitary nebula weigh?
The weight of a planetary nebula can vary significantly, typically ranging from a few times to several hundred times the mass of our Sun. However, most planetary nebulae have masses between 0.1 to 0.6 solar masses. The mass is primarily composed of the remnants of the dying star's outer layers expelled during the late stages of stellar evolution.
The remaining core of a planetary nebula is called a?
The remaining core of a planetary nebula is called a white dwarf. This stellar remnant is composed mainly of carbon and oxygen and represents the final stage in the evolution of stars that were once similar in size to our Sun. As the outer layers of the star are expelled, the white dwarf gradually cools and dims over time.
What is the cycle of the stars?
Stellar Nebula - Average Star- Red Giant - Planetary Nebula - White Dwarf Stellar Nebula - Massive Star - Red Super Giant - Super Nova- Neutron Star Stellar Nebula - Massive star - Red Super Giant -Super Nova - Black Hole
What is the difference between a planetery nebula and a nebula?
A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas
Select the star cycle that is accurate?
Star of one stellar mass, red giant, white dwarf, planetary nebula
What the star life cycle the is accurate?
Star of one stellar mass, red giant, white dwarf, planetary nebula
What is the difference between the Helix Nebula and the Ring Nebula?
The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.
What is the significance of the eskimo nebula?
The Eskimo Nebula, also known as NGC 2392, is a planetary nebula located in the constellation Gemini. It is significant because its distinctive shape resembles a face surrounded by a parka hood, giving rise to its popular name. The Eskimo Nebula is of interest to astronomers for studying the late stages of stellar evolution and the creation of planetary nebulae.
Is planetary nebula a misnomer?
Planetary nebula is a misnomer because it's a nebula but it has nothing to do with planets, it's about stars.
How long does a stellar nebula live for?
A stellar nebula can exist for millions to billions of years, depending on the size and mass of the nebula. These nebulae are the birthplaces of stars and can last until all the matter within them has been used up in the process of star formation.
What is a star called that a star left at the core of a planetary nebula?

What star sheds a planetary nebula?
A star like our sun will shed a planetary nebula after its 'death'
