Where would a nebula be found? A nebula is a cloud of dust and gas in space. Some of the clouds block out the light from the stars behind. These are called dark nebulae. One of the best-known is the Horse … head Nebula.Other dust clouds reflect the light from the stars and shine brightly.These are called bright nebulae.ebula means Cloud in Latin. A nebula is an interstellar cloud of hydrogen, helium, plasma and dust. They are often called stellar nurseries because stars are born within them.

- 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.

Nebula 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.mission nebulae, such as the Eagle Nebula, are vast, glowing clouds of ionised hydrogen and dust where stars are born. Others, such as planetary nebulae, are the bright shells of gas shed by dying stars. Despite their name, planetary nebulae have nothing to do with planets.

- Reflection 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. Such as the Eagle nebula.

Why are nebulae so beautiful if they are all dust? A nebula is not all dust. It is dust and gas and plasma. And It is the dust, gas, and plasma that makes a nebula beautiful. With regards to light source, there are two basic categories of nebula: emission nebula and reflection nebula. Emission nebulae are nebulae in which the ultraviolet light from a star is energizing the gas of the cloud. That causes the cloud to emit light. This is most often evident through emission of the color red, because of the abundance of hydrogen in the cloud.

A Planetary Nebula Sampler A Planetary Nebula Sampler. A planetary nebula forms when a star can no longer support itself by fusion reactions in its center. The gravity from the material in the outer part of the star takes its inevitable toll on the structure of the star, and forces the inner parts to condense and heat up. Planetary Nebula Sampler.

- Next image. The Ring Nebula (M 57) is a planetary nebula about 2300 light years away from us. This is how it looks when a star blows its outer layers at the end of the life. If the star is not big enough to explode in a supernova, it will eject some of its mass as in the case of M 57, the Ring Nebula. The star in the centre of the nebula can still be seen, but it is passing through the last stage of its stellar evolution and is soon to become a white dwarf.

Star Colors and Luminosities: The H-R Diagram Emission nebulae are usually red, because hydrogen, the most common gas in the universe, most commonly emits red light. Reflection nebulae are clouds of dust that simply reflect the light of a nearby star or stars. Reflection nebulae are usually blue, because blue light scatters more easily.n some nebulae, stars form out of large clouds of gas and dust; once some stars have formed inside the cloud, their light illuminates the cloud, making it visible to us. These star formation regions are sites of emission and reflection nebulae, like the famous Orion Nebula shown in the picture on the right.

Planetary nebula This is what causes a planetary nebula to look like it does. Planetary nebulae are very special objects because they can help make more stars. When a star dies, the metals that were in the core of the star are sent to other places in the universe.

Nebulae - Stellar Nurseries Usually nebulae are a mix of these groups. The first group, emission nebulae, are emit light themselves. A very hot and bright, nearby star ionizes (it strips off the electrons) the hydrogen in the nebula. When the free electrons recombine with protons, light is emitted, usually red light. A subgroup of emission nebulae are HII-regions, where massive stars forming are causing the ionization.

The size of these nebulae, known as HII regions, varies depending on the size of the original cloud of gas. New stars are formed in the nebulae.

Stars, Stellar Systems and Nebulae Planetary nebulae are shells of gas thrown out by some stars near the end of their lives. Our Sun will probably produce a planetary nebula in about 5 thousand million years. They have nothing at all to do with planets; the terminology was invented because they often look a little like planets in small telescopes.he gas and dust in the nebula emits light because it is irradiated by nearby emerging stars. Located at a distance of about 1,600 light years, the Orion nebula is the brightest diffuse nebula in the sky, visible to the naked eye.
