A nebula.
That's composed mostly of hot gasses.
Hence, the name.
Hot nebula.
The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.
protostar or nebula
The nebula you are referring to is likely the Swan Nebula, also known as the Omega Nebula. It is a famous emission nebula located in the constellation Sagittarius. The name "Swan Nebula" comes from its resemblance to a swan when viewed in certain images.
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
Swan. To me, that doesn't rhyme. The answer may be the "prawn nebula".
The spectrum of the Orion Nebula (M42) would show emission lines typical of hot, ionized gas, such as hydrogen-alpha and doubly ionized oxygen. This is because the gas in the nebula is being energized by nearby hot stars, causing it to emit light at specific wavelengths.
A nebula, in general, is not particularly hot. They are usually visible due to embedded stars.
You would least expect to find an ionization nebula in a region that lacks hot, massive stars. These stars are responsible for emitting the high-energy ultraviolet radiation needed to ionize the gas in the nebula and make it visible. Therefore, areas with mainly low-mass and old stars would be less likely to host an ionization nebula.

Two forces that act on particles inside a nebula are gravity, which pulls particles together to form new stars and solar systems, and radiation pressure, which pushes particles apart due to the energy emitted by hot stars within the nebula. These forces must be balanced for a nebula to maintain its structure and not collapse or dissipate.
An ionization nebula is typically found in regions where there are hot, massive stars that emit high-energy ultraviolet radiation. These nebulae are commonly located in the spiral arms of galaxies, near star-forming regions or in clusters of young, hot stars.
The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).
The central star of the Ring Nebula is a white dwarf known as HD 229236. It is the remnant core of a low to intermediate mass star that has exhausted its nuclear fuel and shed its outer layers. The white dwarf is hot and compact, surrounded by the colorful nebula that was once its outer layers.
A nebula is a cloud of gas and dust in space where new stars are formed. These regions are often characterized by the presence of young, hot stars surrounded by glowing gas and dark dust.
"The Crab" is a nebula.
