A large gaseous clould found in space?

A large gaseous cloud found in space is often referred to as a nebula. These clouds are composed primarily of hydrogen, helium, and other ionized gases, and they can serve as regions for star formation. Some nebulae are remnants of dead stars, while others are sites where new stars are born. Their stunning colors and shapes are often the result of the interaction of light from nearby stars with the gas and dust in the cloud.
