- A nebula is an interstellar cloud in outer space that is made up of dust, hydrogen and helium gas, and plasma.It is formed when portions of the interstellar medium collapse and clump together due to the gravitational attraction of the particles that comprise them.t is this released matter that forms what is known as a planetary nebula. The planetary nebula is just one of four major types of nebulae. The other three are H II regions, supernova remnant, and dark nebula. Some of the more prominent nebulae are the Crab, Eagle, Orion, Pelican, Ring, and Rosette Nebula.

- 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.

ASTRO CHAPTER 18 The explosion of the star creates a shock wave that compresses nearby interstellar clouds. Yes. When the material from the explosion encounters an interstellar cloud, it creates a shock wave in the cloud that compresses the cloud very suddenly. This sudden compression can initiate star formation in the cloud.

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.

- Nebula 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.There are many types of Nebula, some stars have nebula's around them when they approach the final stages of their lives as in Wolf Rayet stars. 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.

- Nebulae form in three ways: 1. Through gravitational collapse, 2. Through supernova explosion of a massive star, and 3. Through shedding off the outer layers of a less massive star. Through gravitational collapse: Diffuse nebulae are formed from the explosions of older stars, and the leftover hydrogen and helium from the Big Bang.

What Causes a Supernova Explosion? A Supernova Explosion in Process. A supernova occurs when a super massive star explodes. It is a dramatic end to a star’s life. Supernovae (which is the plural form of supernova) become very bright and cause an enormous burst of radiation that can outshine an entire galaxy before disappearing.

Atomic Nuclei Explain How Supernovae Formed Heavier Elements In order for a dying star to end up as a supernova, its core must have been transformed into iron. “Once the core cannot be compressed any further, the compressed matter must expand again in a gigantic explosion, or supernova. This is where the heavy elements of the universe may have been formed.” Atomic collisions

What happens to someone when they get Inguinal Hernia? What Happens. Inguinal hernias typically flatten or disappear when they are pushed gently back into place or when you lie down. Over time, hernias tend to increase in size as the abdominal muscle wall becomes weaker and more tissue bulges through. If you can't push your hernia back into your belly, it is incarcerated. A hernia gets incarcerated when tissue moves into the sac of the hernia and fills it up. This is not necessarily an emergency.

- Emission nebulae are extended clouds of hot, glowing interstellar matter. Associated with star formation, they are caused by hot O-and B-type stars heating and ionizing their surroundings. They are often crossed by dark dust lanes part of the larger molecular cloud from which they formed.

- 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.

- What happens after a supernova? Quick Answer. Depending on the size of the star before it explodes as a supernova, the core of the star either shrinks back into a tiny neutron star or becomes a black hole. If the star is only a few times bigger than the sun, the core becomes a tiny neutron star.

What is a nebula? how does it from a protostar? when does it become a star?? Many nebulae or stars form from the gravitational collapse of gas in the interstellar medium or ISM. As the material collapses under its own weight, massive stars may form in the center, and their ultraviolet radiation ionizes the surrounding gas, making it visible at optical wavelengths.xamples of these types of nebulae are the Rosette Nebula and the Pelican Nebula. 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.

What is a planetary nebula made of? Does it have anything to do with planets? The nebula that forms planets is called a protoplanetary disk or nebula and is the start of a star's life. A planetary nebula is the end of a star's life.lanetary nebula have nothing to do with planets, except for some of them resembling Uranus or Neptune through a telescope. They are in fact the discarded outer layers of stars less than 8 times the mass of the Sun after they've exhausted their supplies of helium in the core.

What two forces balance each other out in order to keep a nebula of dust and gas from collapsing or flying apart? Nebulae are massive collections of gas and dust that usually are very cool around 5-30 kelvin. These nebulae are the remains of dead stars that have long died and have had eno … ugh time to cool themselves from the original energy release of the nova or supernova that created them. Irregularities in the density of the gas causes a net gravitational force that pulls the gas molecules closer together. Some astronomers think that a gravitational or m … agnetic disturbance causes the nebula to collapse.

General Astronomy/Print version A Star's Size. A star begins its life in a contracting nebula of gas and dust. As the density of the material increases under the influence of gravity, compression heats the material. If the material gets hot enough, hydrogen atoms begin fusing together to form helium atoms, and a star is born. A star will spend most of its life, called the main sequence phase, fusing hydrogen into helium. Click the image to see the animation. It's logical that a large nebula (one with a large amount of mass) will form a large star, and a small nebula will form a small star. However, in addition to a star's initial mass, a star's size also depends on the balance between the inward pull of gravity and the outward push of the energy produced by fusion. The entire sequence of a star's evolution can be described in terms of the changing balance between these two opposing forces.

How Nebulae Work The first is a nebula's proximity to the star, and the second is the star's temperature. When a nebula is very close to a hot star, it can absorb large amounts of ultraviolet radiation.This heats the gas to about 10,000 Kelvin (9,726 degrees Celsius or 17,540 degrees Fahrenheit).At such extreme temperatures, the hydrogen gas becomes excited and glows with a fluorescent light.ourtesy NASA and STScIThe Orion Nebula is an emission nebula. It is illuminated and heated by four massive stars known as the Trapezium, which lie near the center of the image. Astronomers generally classify nebulae into two broad categories -- bright and dark.

1) Based on counting the number of galaxies in a small patch of the sky and multiplying by the number of such Here is a brief outline of the current theory of the events in the early history of the solar system: A cloud of interstellar gas and/or dust (the solar nebula) is disturbed and collapses under its own gravity. The disturbance could be, for example, the shock wave from a nearby supernova.

Ways to Identify a Gifted Child While parents may wonder what a gifted child looks like to see if their child looks similar, categorizing a child as gifted is difficult because not everyone defines gifted the same way. Yet, psychologists and educators have researched gifted children enough to provide a profile of the traits these children tend to have. The more one learns about gifted children, the easier it becomes to identify them. High IQ. IQ tests can be used to determine giftedness in some children.
