What is a nebula?

A nebula is a huge cloud of gas and dust in space. Some can be seen with the naked eyes but we can view more through a telescope. A nebula has mostly hydrogen gas and some helium. Sometimes the two gases will glow resulting in a bright nebula. In other cases, the dust will reflect light from nearby stars.
