Some examples of different nebulae include the Orion Nebula, the Crab Nebula, the Eagle Nebula, and the Helix Nebula. These nebulae vary in size, shape, and composition, but they are all vast clouds of dust, gas, and plasma in space.
The pressure caused by the thermal energy of the gas within the nebula pushes outward in all directions, preventing the nebula from collapsing under its own gravity. This pressure acts to counterbalance the force of gravity, maintaining the nebula's size and structure.
The visible cloud of dust and gas in space is called a nebula. Nebulas are often regions where new stars are forming, and they can vary in size, shape, and color.
Yes, a nebula can be much larger in size than a star. Nebulae are vast clouds of gas and dust in space, while stars are relatively small and compact objects that form within these nebulae. Some nebulae can span hundreds of light-years across, whereas stars are typically only a few times the size of Earth.

Massive stars are the center of a distant nebula. The massive stars are formed as the gas in the interstellar medium collapses under its own weight. The size of a nebula depends on the size of the original gas cloud.
A nebula, in general, is not particularly hot. They are usually visible due to embedded stars.
The smallest nebula ever found is the planetary nebula called "K 1-27." Discovered in 1996, it measures only about 0.02 light-years across. This nebula is notable for its compact size and unique structure, which includes a bright central star surrounded by a faint halo of gas. Its small dimensions challenge our understanding of nebula formation and evolution.
Because nebula, like galaxies, do not have a defining edge, it is difficult to determine the exact size but an estimate is the closest you'll get.However, in this case, the difference is large enough.The Tarantula Nebula is about 15 times larger than the Carina Nebula.Tarantula ~ 1,000 light years acrossCarina ~ 65 light years across.
A stellar nebula can exist for millions to billions of years, depending on the size and mass of the nebula. These nebulae are the birthplaces of stars and can last until all the matter within them has been used up in the process of star formation.
Superclusters.

No. The sun is much closer to the size of the star that exploded almost 1,000 years ago, whose expanding outer shell is seen today as the Crab Nebula.
The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).
A nebula IS a cloud of dust and gas loosely held together by gravity.
