Verified archiveThe correct statement is: Nebulas are large clouds of gas and dust in space.
A nebula is a vast region in space containing gas (mostly hydrogen and helium) and dust. They can be the birthplace of stars (like stellar nurseries) or remnants of dead stars (like planetary nebulae). While some nebulae can emit light due to the ionization of their gas, the key characteristic that defines a nebula is its composition as a cloud of gas and dust.
