Definitions &Translations Nebula (n.). (Astron.) A faint, cloudlike, self-luminous mass of matter situated beyond the solar system among the stars. The term was originally applied to any diffuse luminous region. Now, technically, it is applied to interstellar clouds of dust and gases (diffuse nebula).

Planetary nebula 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 appeared to him to resemble the rounded shapes of planets. mechanism for formation of most planetary nebulae is thought to be the following: at the end of the star's life, during the red giant phase, the outer layers of the star are expelled by strong stellar winds.

- The definition of a constellation is a group of stars that create a pattern in the sky. The International Astronomical Union (IAU) met for the first time in 1922. They picked the 88 constellations which we use today.

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.

Nebula 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. wayne of the best examples of this is the Crab Nebula, in Taurus. The supernova event was recorded in the year 1054 and is labelled SN 1054. The compact object that was created after the explosion lies in the center of the Crab Nebula and is a neutron star. Other nebulae may form as planetary nebulae.

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.The process is similar to that of a neon light.t is a cloud of dust and gas that reflects the light energy from a nearby star or group of stars. Reflection nebulae are frequently the sites of star formation. They usually tend to be blue in color because of the way that the light is scattered. Blue light is scattered more efficiently.

nebula The remnant of a supernova explosion is a glowing filamentary nebula of, generally, symmetric shape. In a supernova explosion a star ejects a substantial part of its mass (about 1 solar mass) at a speed of about 10,000 km/sec. The resulting spherically symmetric shock wave travels through the interstellar gas.

Reflection nebulae are clouds of dust that simply reflect light from nearby stars. The dust particles of reflection nebulae usually only scatter blue light, so the appearance is blue.

- 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.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.

Chapter 12: The Solar System Review a nebula cloud of gas, ice, and dust slowly formed into space from an explosion. since asteroids are made of a similar material that formed the planets, the nebula cloud might have exploded when asteroids were nearby.

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.

Planetary nebula NGC 6326, a planetary nebula with glowing wisps of outpouring gas that are lit up by a binary central star. A planetary nebula, often abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives.

Why are nebulae so beautiful if they are all dust? Reflection nebulae are nebulae in which the gas of the cloud is not emitting its own light, but the dust and gas are reflecting light from nearby stars. Due to scattering, different colors can result. However, scattering leads to a predominance of blue light.

Nebular hypothesis The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from nebulous material.

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. gasesxamples 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. The formed stars are sometimes known as a young, loose cluster.

Definitions &Translations Cosmos. In the general sense, a cosmos is an orderly or harmonious system. The word derives from the Greek term κόσμος, literally meaning order or ornament and metaphorically world, and is antithetical to the concept of chaos. Today, the word is generally used as a synonym of the Latin loanword Universe. The word cosmetics originates from the same root.

emission nebula A nebula that absorbs ionizing ultraviolet radiation from nearby hot stars or star remnants and reemits it as visible light. HII regions, planetary nebulae, and nebulae created by the explosion of supernovae are different kinds of emission nebulae.
