This is known as an emission nebula.
In many emission nebulae, an entire cluster of young stars is doing the work.
A small part of the emission nebula NGC 6357.
The large emission nebula dubbed IC 1805 looks, in whole, like a heart.
Planetary nebulae, represented here by the Ring Nebula, are examples of emission nebulae.
Most emission nebulae are about 90% hydrogen, with the remaining helium, oxygen, nitrogen, and other elements.
NGC 1955(also known as ESO 56-SC121)is an open cluster associated with an emission nebula located in the Dorado constellation.
NGC2264 is the location where the Cone Nebula, The Stellar Snowflake Cluster andthe Christmas Tree Cluster have formed in this emission nebula.
NGC 2029(also known as ESO 56-EN156) is a emission nebula in the Dorado constellation and is part of the Large Magellanic Cloud.
Collisions between gas in the inner and outer regions are creating many hot blue stars andpink emission nebula.
NGC 1934(also known as ESO 56-SC109) is an emission nebula located in the Dorado constellation and part of the Large Magellanic Cloud.
NGC 1980(also known as OCL 529, Collinder 72 and The Lost Jewel of Orion[4])is a young open cluster associated with an emission nebula in the constellation Orion.
NGC 1935(also known as ESO 56-EN110 and IC 2126)is an emission nebula which is part of the larger LMC-N44 nebula in the Dorado constellation.
First observed in the late 19th century by Sherburne Wesley Burnham, Herbig-Haro objects were not recognized as being a distinct type of emission nebula until the 1940s.
Among the several different types of emission nebulae are H II regions, in which star formation is taking place and young, massive stars are the source of the ionizing photons;
The objects were first observed in the late 19th century by Sherburne Wesley Burnham,but were not recognised as being a distinct type of emission nebula until the 1940s.
NGC 1974(also known as NGC 1991 and ESO 85-SC89)is an open cluster associated with a emission nebula which is located in the Dorado constellation which is part of the Large Magellanic Cloud.
The objects were first observed in the late 19th century by Sherburne Wesley Burnham,but were not recognised as being a distinct type of emission nebula until the 1940s.
NGC 2032(also known as ESO 56-EN160 and the Seagull Nebula) is an emission nebula in the Dorado constellation and near the supershell LMC-4[2] and it consists of NGC 2029, NGC 2035 and NGC 2040.
The PPN phase continues until the central star reaches around 30,000 K and it is hot enough(producing enough ultraviolet radiation) to ionize the circumstellar nebula(ejected gases)and it becomes a kind of emission nebula called a PN.
Due to the prevalence of hydrogen in interstellar gas,and its relatively low energy of ionisation, many emission nebulae appear red due to the strong emissions of the Balmer series.
NGC 2174(also known as Monkey Head Nebula) is an H II[1] emission nebula located in the constellation Orion and is associated with the open star cluster NGC 2175.[1] It is thought to be located about 6,400 light-years away from Earth.
Finally, just barely visible to the unaided eye but quite striking here is Barnard's Loop-a huge gaseous emission nebula surrounding Orion's Belt and Nebula discovered over 100 years ago by the pioneering Orion photographer E. E. Barnard.
This is within the N119 emission nebula, which has a distinctive spiral shape.[1] It is one of the visually brightest individual stars in the LMC, at some times the brightest.[2] There are only a handful of other 9th magnitude stars in the LMC, such as the yellow hypergiant HD 33579.
NGC 2035(also known as ESO 56-EN161 and the Dragon's Head Nebula) is a emission nebula and a H II region in the Dorado constellation and part of the Large Magellanic Cloud.[2] It was discovered by James Dunlop on August 3, 1826.
The east side of theN11 complex is N11C(NGC 1769), an emission nebula containing at least two compact open clusters.[12] Outside the main"bubble" of N11 to the northeast is N11E, also known as NGC 1773, a small bright nebula containing several massive young stars.
The Cygnus Loop(radio source W78, or Sharpless 103) is a large supernova remnant(SNR)in the constellation Cygnus, an emission nebula measuring nearly 3° across.[1] Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range.[1] Radio, infrared, and X-ray images reveal the complete loop.
Among the several different types of emission nebulae are H II regions, in which star formation is taking place and young, massive stars are the source of the ionizing photons; and planetary nebulae, in which a dying star has thrown off its outer layers, with the exposed hot core then ionizing them.
The Wreath Nebula also known as Barnard 3 or IRAS Ring G159.6-18.5is an emission nebula and H II region with a radius of about 22 light-years, located about 1,000 light-years away within our Milky Way in the Perseus molecular cloud complex, near the boundary with the constellation of Taurus.
NGC 1929(also known as ESO 56-EN107)is an open cluster associated with the emission nebula located within the N44 nebula in the Dorado constellation and part of the Large Magellanic Cloud.[3] It was discovered by James Dunlop on August 3 1826.[4] Its apparent magnitude is 14.0, and its size is 0.8 arc minutes.
