Is a Nebular a dying/dead star?

Answer 1

A "Nebula" is a term that applies to things that aren't "points of light" in the sky.
Some nebula are the remnants of supernovas, which is a dying star. Some nebula are gas clouds, where stars are forming.

Answer 2

A nebula is any cloud of gas and dust in space. Some nebulae are the remnants of dead or dying stars. Smallish stars, such as our sun, lose their outer layers during their red giant phase. The remaining collapsed dead stellar core is very hot, and puts out enough ultraviolet light to cause the cloud of discarded gas around it to glow; this is called a planetary nebula.

Larger stars also shed their outer layers, though more violently. They get stripped down to a still-active core, which illuminates the surrounding gas. The core is called a Wolf-Rayet star, and the gas a Wolf-Rayet nebula.

The third type of nebular star remains is called a supernova remnant. This is a rapidly expanding shell of gas around the spot where an exploded star used to be. There may be a neutron star or black hole at the center, or there may be nothing left at all. These nebulae glow mostly from the energy of the expanding shock wave, though some younger ones, such as the Crab Nebula (M1) are also lit up by their central neutron star.

Some nebulae instead contain new stars being born, as they collapse into dense clumps under the influence of their own gravity. All the nebulae we can see now contain material expelled by supernovae and other dying stars. The dust, and any gas heavier than helium is from dead stars, but some of the material may be primordial hydrogen and helium that has never been part of a star..

Answer 3

A planetary nebula is the result of a dying star with a mass less than 8 solar masses. nebular is an adjective.

Answer 4

There are several types of nebula
planetary nebula are the result of a small to medium star blowing off its outer shell on the way to becoming a white dwarf.
the Orion Nebula is a gaseous nebula that is the birth place of a star cluster.
The Crab nebula is a supernova remnant- most definitely the final resting place of a star that is now nothing but a rotating neutron star or pulsar.
Eventually the Crab material will condense into another gaseous nebula that will form a new star

Answer 5

Hi!,
A nebula is a region of interstellar gas and dust. There are four main types:
1. Emission nebulae e.g Orion Nebula: which emit light and radiation. The source of the ultraviolet radiation coming from 'hot' stars.
2. Planetary nebulae: An emission nebula formed when a red giant or supernova sheds it's outer layers, leaving a hot core to 'excite' the gas e.g Ring Nebula
3. Reflection nebulae: these nebulae result from the scattering by dust particles of light from background stars
4. Dark nebulae: these are not luminous. Interstellar gas and dust absorb light from background stars, producing apparently dark patches in the sky

Hope this helps!

Answer 6

A nebula is not a dead/dying star. A nebula is a collection of dust, gas, and plasma spanning many lightyears in space. The dust, gas, and plasma in a nebula over time will converge onto one point because of gravity, and when that happens, essentially a star is born.

Answer 7

Close. A nebula is the debris spewed out from a dying/dead star after a (super)nova. In time this debris coalesces to form new stars.

Answer 8

I watched "the universe" yesterday and i believe it said it was the first stage of life of a star. That is large clouds of condensing gas and dust. You might be thinking of nova which is what happens to a relatively small star like our sun.

Answer 9

i did not find the term nebular but click on the link hope it helps

Answer 10

i think there are different types, they tend to be the remains of stars and can be the birth places of new stars
