No, they are ionized gases thrown off stars near the end of their fusion cycles. They are expanding clouds of matter, quite different from the nebulae in which stars form.
The term that refers to clouds of dust and gas composed of various chemical elements is "nebula." Nebulae are often the sites of star formation, as the dense regions within them can collapse under gravity to form new stars and planetary systems. They can also be remnants of dead or dying stars, such as supernova remnants or planetary nebulae.
There are mainly four types of nebulae: emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae glow due to the energy emitted by nearby stars, reflection nebulae reflect light from nearby stars, dark nebulae are dense clouds that block light, and planetary nebulae are the remnants of dying stars. Each type of nebula differs in its composition, appearance, and the processes that create them.
These are typically called Bok globules. They are dense, cold clouds of gas and dust where new stars are born. Due to their small size and high density, they are often considered as potential sites for the formation of star clusters or individual stars.
There are several stages involved in the making of a planetary nebula. Take the sun for example, which is of course a star. Eventually the sun will run out of "fuel" (hydrogen) and grow to a red giant, and then when it's completely out "fuel" the sun will loose it's blown up outter layers and that layer will form a ring of gas around the remaining star. After that it will just be a white dwarf left, doomed to a slow death! Now, this was a long story short. But I think you can read more about it on some other sites!
Nebulas are often referred to as the building blocks of the universe because they are vast clouds of gas and dust that serve as the primary sites for star formation. Within these regions, gravity pulls material together to form stars and planetary systems, essentially creating the fundamental components of galaxies. The elements produced in stars subsequently enrich the interstellar medium, contributing to the formation of new stars and planets, thus perpetuating the cycle of cosmic evolution.

Dark nebulae are dense clouds of gas and dust in space that block the light from objects behind them, making them appear as dark patches against the background of stars and other celestial bodies. They are often sites of star formation, as their dense material can collapse under gravity to form new stars. These nebulae are typically cold and thick, containing a mixture of hydrogen, helium, and other elements, which contribute to their opacity. Examples include the Horsehead Nebula and the Coalsack Nebula.
Some good sites for facts about Uranus include NASA's Solar System Exploration page on Uranus, the European Space Agency's website, and the Planetary Society's resources on Uranus. These sites provide accurate and up-to-date information about the planet's characteristics, composition, and history.
