Planetary nebula A planetary nebula is a nebula that is made up of gas and plasma. They are made by certain types of stars when they die. They are named this because they look like planets through small optical telescopes.his 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 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.

- 1 The Ring Nebula is a planetary nebula, these type of nebula are created when a small star sheds it mass at the end of its life span.  The core of the dead star remains in the form of white dwarf, it ionizes the surrounding gas producing an impressive light display.

- 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.

Emission nebula Emission nebula. An emission nebula is a nebula formed of ionized gases that emit light of various colors. The most common source of ionization is high-energy photons emitted from a nearby hot star.

Planetary system Planetary system. A planetary system is a set of gravitationally bound non-stellar objects in orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks.

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.

Boomerang Nebula The Boomerang Nebula is a protoplanetary nebula located 5,000 light-years away from Earth in the constellation Centaurus. It is also known as the Bow Tie Nebula and catalogued as LEDA 3074547. The nebula's temperature is measured at 1 K (−272.15 °C; −457.87 °F) making it the coolest natural place currently known in the Universe. The Boomerang Nebula is believed to be a star system evolving toward the planetary nebula phase.

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 denser regions which attract further matter and eventually will become dense enough to form stars

- This is often when and where you can ask for a jury trial, if your state is one that allows it for ordinary traffic violations. (If you are not allowed arraignment in your state, be sure to ask the court clerk how to ask for a jury trial, if you are allowed one.)

As these atoms fall back to lower energy states, they emit radiation.The process is similar to that of a neon light. fine example of an emission nebula is the Orion Nebula (M42). Reflection Nebula-A reflection nebula differs from an emission nebula in does not emit radiation of its own. It is a cloud of dust and gas that reflects the light energy from a nearby star or group of stars.

Helix Nebula See also: Planetary nebula, Lists of nebulae. The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.

What Is a Nebula? Usually several light years across, a nebula is an extremely large cluster of clouds and dust often found between stars. Nebulae are made of many elements including carbon, hydrogen and helium.

THE PLANETARY NEBULAE See the spectra of NGC 2440, the Ring Nebula in Lyra, NGC 7009, IC 418, and the original nebular spectrum, that of NGC 6543. Planetary nebulae, some of the loveliest objects in the sky, are complex shells of gas that have been ejected by dying advanced giant stars like Mira.

What is a nebula? how does it from a protostar? when does it become a star?? A nebula (Latin for cloud; pl. 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 Way.

Planet A planetary-mass object (PMO), planemo, or planetary body is a celestial object with a mass that falls within the range of the definition of a planet: massive enough to achieve hydrostatic equilibrium (to be rounded under its own gravity), but not enough to sustain core fusion like a star.

Types of nebula PLANETARY NEBULAplanetary nebulae, have nothign to do with planets, instead, they are the gas remnants thrown out by some stars near the end of thier lifespan, our own sun will probably produce a planetary nebula in about 5 000 000 000 years from now planetary nebulae do NOT produce stars.

- According to the nebula hypothesis, the Solar System began as a nebula, an area in the Milky Way Galaxy that was a swirling concentration of cold gas and dust. Due to some perturbation, possibly from a nearby supernova, this cloud of gas and dust began to condense, or pull together under the force of its own gravity.

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

- 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.
