What is a nebula? how does it from a protostar? when does it become a star?? A nebula (Latin for cloud; pl. nebulae, nebulae, nebulæ or) nebulas is an interstellar cloud of, dust, hydrogen helium and other ionized. Gases, originally nebula was a name for any diffuse astronomical, object including galaxies beyond The Milky. wayxamples 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.

Stars Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

- A nebula is a large cloud that consists of dust and gas. Their  massive size can be as wide as a trillion miles. A huge release of  gas in the interstellar medium produces t … he nebula. The material  contained in the nebula collapses against itself and stars are  formed.hen a protostar is formed from the gas in a nebula, it is the  result of gravitational attraction. This attraction causes matter  to clump together until enough mass has ac … cumulated that it  collapses in on itself and begins the process of fusion.

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.

- A star forms a nebula when it runs out of fuel. The star either  becomes a red giant or a supergiant, then the star would be blown  off into space either by expansion or exp…losion. The outer layers,  which was released into space, would become a nebula, or sometimes  a part of a larger nebula.

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.

- The elements formed in these stages range from oxygen through to iron. During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

- We often think of the vast areas of space between the stars as being completely empty. However, this is not really true. Much of the space between the stars is filled with atomic and molecular gas (primarily hydrogen and helium) and tiny pieces of solid particles or dust (composed mainly of carbon, silicon and oxygen). In some places this interstellar material is very dense, forming nebulas.

- In the outer solar nebula temperatures were cool enough for the abundant gases to accumulate and be held by proto-planets. As a result the Jovian planets (Jupiter, Saturn, Uranus, and Neptune) are gas giants, made mostly from hydrogen, helium, and hydrogen compounds like methane (CH4) and ammonia (NH3).

Nebulae Types of Nebulae. Emission Nebula-An emission nebula is a cloud of high temperature gas. Within this type of nebula, a star energizes the atoms in the cloud with ultraviolet radiation. As these atoms fall back to lower energy states, they emit radiation.hese colors are the result of different elements within the nebula. Most nebulae are composed of about 90% hydrogen, 10% helium, and 0.1% heavy elements such as carbon, nitrogen, magnesium, potassium, calcium, iron.

How Do Planets Form? According to our current understanding, a star and its planets form out of a collapsing cloud of dust and gas within a larger cloud called a nebula. As gravity pulls material in the collapsing cloud closer together, the center of the cloud gets more and more compressed and, in turn, gets hotter. This dense, hot core becomes the kernel of a new star. Meanwhile, inherent motions within the collapsing cloud cause it to churn.

- So, 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.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.

Are we really all made of stardust? As time went on, young stars formed when clouds of gas and dust gathered under the effect of gravity, heating up as they became denser. At the stars’ cores, bathed in temperatures of over 10 million degrees C, hydrogen and then helium nuclei fused to form heavier elements. A reaction known as nucleosynthesis.

Women at war: should female soldiers serve in close combat? Physically and emotionally, few women will have the aptitude to join the combat arms, he writes in the Times. There are widespread concerns that the inclusion of women in the military will result in lower physical standards for all soldiers, as, they argue, women will be unable to meet current fitness targets.emale soldiers are allowed to serve in combat roles in other countries including the US, Australia, France and Israel, and commentators argue that Britain is lagging behind.

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.
