Are planetary nebulae sites for planet formation?
No, planetary nebulae are not sites for planet formation. Planetary nebulae are the outer layers of a dying star that have been expelled into space, while new planets form in protoplanetary disks around young stars.
The names of the different types of nebulae?
The main types of nebulae are emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae glow with their own light, often due to hydrogen gas being ionized by nearby stars. Reflection nebulae reflect light from nearby stars. Dark nebulae are dense clouds of dust that obscure light. Planetary nebulae are the ejected outer layers of dying stars.
Which of the following is true regarding planetary nebulae?
Planetary nebulae are formed from the ejected outer layers of certain types of stars, such as red giants, during the late stages of their evolution. Despite their name, they have nothing to do with planets. They often have complex and beautiful shapes due to interactions with the surrounding interstellar medium.
Which type of nebulae formation occurs after a main sequence star casts of its outer layers?
planetary
Why is the term planetary nebula a misleading way to describe the ring of expanding gas thrown out by a red giant during its transformation into a white dwarf?
The term "planetary nebula" is misleading because it suggests a connection to planets, while these nebulae are actually formed from the outer layers of a dying star, specifically a red giant. The name originated from their round, planet-like appearance in early telescopic observations, but they have nothing to do with planets themselves. Instead, planetary nebulae are the remnants of stellar evolution, showcasing gas and dust expelled by stars, often leading to the formation of new stars. Thus, the terminology inaccurately conveys the true nature of these celestial phenomena.
Is planetary nebulae surrounded by planets?
no
Which is biggest a planetary nebula a planetary system or a galaxy?
A galaxy is the biggest among the three. Galaxies contain billions to trillions of stars, as well as other celestial objects like planets and planetary nebulae. A planetary system refers to a star with its orbiting planets, while a planetary nebula is a glowing shell of gas ejected by a dying star.
Where does matter for star nurseries comes from?
Planetary Nebulae
Are planetary nebulae sites for planet formation?
No, planetary nebulae are not sites for planet formation. Planetary nebulae are the outer layers of a dying star that have been expelled into space, while new planets form in protoplanetary disks around young stars.
What has the author Timothy Barker written?
Timothy Barker has written: 'The ionization structure of planetary nebulae' -- subject(s): Planetary nebulae
How many kinds of Nebula's are there?
*the correct term is nebulae. a nebulae is a could of many gases and dust, where stars are created. TYPES: Diffuse Nebulae- the most common type. it is interstellar, which means among the stars, and not part of any galaxy. Planetary Nebulae- completely unrelated to planets. planetary nebulae is when gas and plasma are formed after certain types of stars die. it sometimes looks like gas planets, like neptune and uranus, hence the name. Reflection Nebulae- clouds of dust that reflect the light of nearby stars, though they are not nebulae, because they do not create stars. Protoplanetary Nebulae- a point in the lifetime of an astronomical object (star). protoplanetary nebulae, or preplanetary nebulae, emit light, much like reflection nebulae Emission Nebulae- a could of ionized gas which emits colorful lights
Are there any planetary Nebula in your galaxy?
Yes. There are many planetary nebulae in our galaxy.
The names of the different types of nebulae?
The main types of nebulae are emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae glow with their own light, often due to hydrogen gas being ionized by nearby stars. Reflection nebulae reflect light from nearby stars. Dark nebulae are dense clouds of dust that obscure light. Planetary nebulae are the ejected outer layers of dying stars.
What are examples of nebulae?
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
How are nebula classified?
a nebula is classified by a planetary nebulae
What are planetary nebulae the expanding outer layer of?
Planetary nebulae are the expanding outer layers of dying stars, typically those similar in mass to the Sun, that are in the late stages of stellar evolution. When such a star exhausts its nuclear fuel, it expels its outer envelope, creating a glowing shell of ionized gas around the remaining core, which becomes a white dwarf. The term "planetary nebula" is a misnomer; it originated from their planet-like appearance in early telescopes, rather than any relation to planets. These nebulae are crucial for enriching the interstellar medium with heavy elements, contributing to the formation of new stars and planets.
How are nebulae related to the formation of planetary systems like the solar system?
Solar systems are formed by nebulae. The larger pieces of dust and other materials attract the smaller ones, get bigger, and attract even more pieces of random things, and so on, until a star and sometimes planets are eventually formed.
