Planetary nebulae Planetary nebulae are astronomical objects made up primarily of gaseous materials. They are extended in size and fuzzy in appearance, and generally show some degree of symmetry. The nebula is illuminated by a central star, which sometimes is too faint to be seen.

- The Eagle Nebula is a diffuse emission nebula. A nebula is a region of interstellar gas and dust. Emission nebulae are clouds of ionized gas.The ionization comes from an extr … emely hot star that sends high-energy photons to the nebula. These nebulae usually appear reddish.eflection nebula are clouds of dust which are simply reflecting the light of a nearby star or stars. Such as the Witch Head Nebula. Emission nebula is a cloud of ionized gas (plasma) emitting light of various colors.

- Instead the light is reflected off the dust in the nebula so it is similar to the visible light given off by stars. Planetary nebulae are formed when stars similar to the size of the Sun use up the hydrogen in their core and instead begin fusing hydrogen in an outer shell surrounding the core. This results in them expanding to hundreds of times their original size and becoming red giants.

- Release type: American Astronomical Society Meeting. This Hubble telescope snapshot of MyCn18, a young planetary nebula, reveals that the object has an hourglass shape with an intricate pattern of etchings in its walls. A planetary nebula is the glowing relic of a dying, Sun-like star. The results are of great interest because they shed new light on the poorly understood ejection of stellar matter that accompanies the slow death of Sun-like stars.

- Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.

Constellations Hubble Space Telescope view of M42 [NASA/ESA] One of the objects in the sword isn't a star at all. It's M42, the Orion Nebula, which is a cloud of gas and dust that's like a giant fluorescent bulb. M42 is part of a giant complex of clouds of interstellar gas and dust. Pockets of this material are collapsing to give birth to new stars.

Definitions &Translations Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula. In these regions the formations of gas, dust, and other materials clump together to form larger masses, which attract further matter, and eventually will become massive enough to form stars.

Difference Between Nebula and Galaxy Nebula. Nebulae are large collections of interstellar gas and dust particles. Most nebulae can be interpreted as a denser region of the interstellar medium accreting under gravity; others are remnants of stars after the end of their lifetime. They mainly consist of hydrogen and helium.

Chapter 1: The Earth System Describe the nebular hypothesis. 1. A diffuse, slowing rotating cloud begind to contract due to gravity 2. As a result of contraction and rotation, a flat, rapidly rotating disk forms with the matter concentrated at the venter that will become the proto-Sun. 3. The photo sun is so compressed and so hot that nuclear fusion begins. 4. Mass turns into energy and like an H-bomb, an explosion occurs. 5.

What is a planetary nebula? Confidence votes 119. A planetary nebula is created when a star blows off its outer layers after it has run out of fuel to burn. These outer layers of gas expand into space, forming a nebula, which is often the shape of a ring or bubble. Answer   A nebula is a large cloud of gas in space, a planetary nebula is the large cloud of expanding superheated gas caused by the explosion of a red giant or oth … er very large, very hot star. Neither have anything to do with planets. 4 people found this useful. Answered.

Planetary Nebula: Gas and Dust, and No Planets Involved Other types of nebulae include emission nebulae, which are clouds of ionized gas emitting light of various colors; dark nebulae, which are clouds of gas so dense that background light is blocked; and protoplanetary nebulae, which occur when a star starts to shed its outer layers before becoming a planetary nebula.aturn Nebula NGC 7009: Located in the constellation Aquarius, the Saturn Nebula, or NGC 7009, has a bright central star surrounded by a football shaped array of gas and dust. Stingray Nebula (Hen-1357): The youngest known planetary nebula, Hen-1357 is as large as 130 solar systems.

Planetary nebula Theoretical models predict that planetary nebulae can form from main-sequence stars of between one and eight solar masses, which puts the progenitor star's age at greater than 40 million years. Although there are a few hundred known open clusters within that age range, a variety of reasons limit the chances of finding a planetary nebula within.

It is actually the accumulation of gas and plasma given off by a star that is about to bade farewell to the universe.They are so named because their appearance through a small optical telescope closely resembles a giant planet. planetary nebula is not a planet, although its name often gives that initial impression.

What is a nebula? Space and astronomy A nebula is a bunch of atoms and molecules floating in outer space, like a cloud of dust. More than one nebula are called nebulae, because-ae is the plural ending in Latin, just as-s is the plural ending in English.Nebula is the Latin word for a cloud.ventually, inside some nebulae, the dust thickened in some places enough to form new stars, or to form planets around those stars. New nebulae are still forming today, whenever a star explodes into a supernova. One example is the Crab Nebula, which formed in 1054 AD.

The word nebula is Latin for mist or cloud, and the term planetary nebula is a misnomer that originated in the 1780s with astronomer William Herschel because, when viewed through his telescope, these objects resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and

- You can think of this as the nebula-star-nebula cycle. Stars that evolve into red giants can lose their outer layers during pulsations in their outer layers, known as their atmospheres. This released matter is typically 97% hydrogen and 3% helium, with a few other trace materials.o, it is this dispersed matter that eventually collapses and forms a nebula. Nebulae, like the Orion Nebula, are often favorite astronomical objects of scientists who want to learn more about stellar or planetary formation.
