Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
The answer will depend on the amount of matter in the nebula.
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
An island comprising billions of stars and nebulae, held together by gravity.
Without gravity, objects would float freely in space, and there would be no weight or pressure on our bodies. Everything would move in straight lines unless acted upon by another force. The lack of gravity would have a profound impact on how we live and interact with our environment.
Gravity put all matters of the Universe together, Stars, Galaxy, Nebulae and many other things.
Astronomers believe that stars, planets, and other celestial objects are 'born' in nebulae. Nebulae are vast clouds of gas and dust in space that can eventually collapse under their own gravity to form new celestial bodies. This process of stellar birth is essential for the formation and evolution of galaxies.

emission nebulae and reflection nebulae.
The different types of nebulae include emission nebulae, reflection nebulae, and dark nebulae. Emission nebulae are clouds of gas and dust that emit light, reflection nebulae reflect light from nearby stars, and dark nebulae are dense clouds of dust that block the light from behind them.
Nebulae are vast clouds of gas and dust in space, often serving as stellar nurseries where new stars are born. They can be categorized into different types, such as emission nebulae, which glow due to ionized gas, and reflection nebulae, which shine by reflecting light from nearby stars. Nebulae can also be remnants of dying stars, known as planetary nebulae, or supernova remnants, showcasing a variety of colors and structures. Their intricate shapes and vibrant hues result from the interplay of gravity, radiation, and cosmic winds.
The main types of nebulae are emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae glow with their own light, often due to hydrogen gas being ionized by nearby stars. Reflection nebulae reflect light from nearby stars. Dark nebulae are dense clouds of dust that obscure light. Planetary nebulae are the ejected outer layers of dying stars.
