- The Crab Nebula (catalogue designations M 1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.It is not, as its name might suggest, in Cancer.n 1928, Edwin Hubble proposed associating the cloud to the star of 1054, an idea which remained controversial until the nature of supernovae was understood, and it was Nicholas Mayall who indicated that the star of 1054 was undoubtedly the supernova whose explosion produced the Crab Nebula.

General Astronomy/Print version Protostar Herbig-Haro 34. Protostars are formed in star nurseries called nebulas, while nebulas are areas of higher dust and gas densities relative to the surrounding interstellar space. Nebulas are made up of mostly hydrogen and a little helium, although more massive elements and even molecules are also ubiquitous.

Emission, Dark, and Reflection Nebulae A nebula is a cloud of gas or dust in space that may reflect light emanating from nearby stars. 'Nebulae' is just the plural form of 'nebula.' A nebula is the location of where something called the interstellar medium (ISM) is densest.n emission nebula is a glowing cloud of ionized gas that is excited by ultraviolet radiation absorbed from hot nearby stars. Such a star must be hotter than 25,000 K to emit enough UV radiation to ionize the gas. When a gas is ionized, it's excited and produces an emission spectrum with a distinct pink color.

Crab Nebula The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 2.0 kiloparsecs (6,500 ly) from Earth. It has a diameter of 3.4 parsecs (11 ly), corresponding to an apparent diameter of some 7 arcminutes, and is expanding at a rate of about 1,500 kilometres per second (930 mi/s), or 0.5% c.n 1928, Edwin Hubble proposed associating the cloud to the star of 1054, an idea which remained controversial until the nature of supernovae was understood, and it was Nicholas Mayall who indicated that the star of 1054 was undoubtedly the supernova whose explosion produced the Crab Nebula.

Nebulae A 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.Reflection nebulae are frequently the sites of star formation. fine example of an emission nebula is the Orion Nebula (M42).

Dungeness Crab  ( Cancer magister/ syn. Metacarcinus magister)Species Profile Similar Species. There are eight congeners (same genus) to the Dungeness crab. Several of these, the European edible crab, Cancer pagurus, Jonah crab, Cancer borealis, and Atlantic rock crab, Cancer irroratus, are commercially harvested. The red rock crab, Cancer productus, is harvested by sport fishermen in Oregon.

Crab Nebula & Light Years Question! Please Help!? the astronomical object known as the crab nebula is the remnant of an exploded star. the explosion was seen by the chineses in AD 1054. however the crab nebula is about 3500 light years fromt he earth. in what earth year did the star actually explode?? please i have NO idea where to start for this.... Follow.

'X' shape in Milky Way confirmed via Twitter Perhaps the most famous image from the Hubble Space Telescope (HST) is that of the Crab Nebula. A nebula is a mixture of hot gas, dust and simple elements like hydrogen and helium. The Crab Nebula is approximately 6,500 light-years from Earth in the constellation Taurus.

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.

Hermit Crabs: Land Hermit Crab Species Coenobita cavipes. Cavipe hermit crabs are most often shades of purple or orange, and you can recognize them from their bright red eye-stalks and feelers. These crabs have a stripe on their big claw, and are very picky about their shells, preferring shells with D-shaped openings, snail shells, and murex shells.

Holly Sweat, Smithsonian Marine Station at Fort Pierce. The giant hermit crab, Petrochirus diogenes, is one of the most distinct hermit crab species in Florida. The portion of the body directly behind the eyes, called the anterior shield, is flattened, roughly square in shape, with tufts of hairs called setae scattered across the surface (Williams 1984).

Decorator crab Bateson, in a much quoted passage, describes crabs of the genera Stenorhynchus and Inachus: the crab tears a piece of seaweed in its claws, chews it, and then rubs it firmly on its body until it catches on the Velcro-like hooked setae, curved hairs which permit camouflage materials to be attached.

Crab Nebula At the center of the nebula lies the Crab Pulsar, a neutron star (or spinning ball of neutrons), 28–30 km across, which emits pulses of radiation from gamma rays to radio waves with a spin rate of 30.2 times per second. The nebula was the first astronomical object identified with a historical supernova explosion.he nebula was observed by John Bevis in 1731; it corresponds to a bright supernova recorded by Chinese and Arab astronomers in 1054. At X-ray and gamma-ray energies above 30 KeV, the Crab is generally the strongest persistent source in the sky, with measured flux extending to above 10 12 eV.

Look for the Crab Nebula Science of the Crab Nebula. The Crab Nebula is the remnant of a massive star that self destructed in an enormous supernova explosion. This is known as a Type II supernova, a typical result for stars at least 8 times more massive than our sun.

Stages of star life? The Crab Nebula is the final stage of life for a massive star, It's the remnant of a core collapse supernova that destroyed a massive star, leaving behind a neutron star that energizes the surrounding nebula into glowing. The Ring Nebula is merely the final stage of a Sun like star's life.

- Although not a large constellation, Scutum contains several open clusters, as well as a globular cluster and a planetary nebula. The two best known deep sky objects in Scutum are M11 (the Wild Duck Cluster) and the open cluster M26 (NGC 6694). The globular cluster NGC 6712 and the planetary nebula IC 1295 can be found in the eastern part of the constellation, only 24 arcminutes apart.

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.

Planetary nebulae Planetary nebulae are astronomical objects made up primarily of gaseous materials. They are extended in size and fuzzy in appearance, and generally show some degree of symmetry. The nebula is illuminated by a central star, which sometimes is too faint to be seen.

Nebula Red Dwarf White Dwarf Supernova Neutron Star Black Hole A nebula is a cloud of hydrogen gas and dust floating in space. These nebulae are where stars are born.There are many different types of nebulae, such as an Emission Nebula.ega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive its expected lifetime is also one tenth of that of the Sun; both stars are at present approaching the midpoint of their life expectancies.

- 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.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.
