gas clouds
Interstellar vapor formations
Gas clouds are vast accumulations of gas in space, primarily hydrogen and helium, that serve as the raw material for star formation.
Nebulae are gas clouds, as are the diffuse regions between galaxies.
Astronomers study gas clouds to understand cosmic evolution: The telescope detected gas clouds in the early universe.
On Earth, gas cloud typically means a dangerous concentration of airborne chemicals: Residents evacuated ahead of the gas cloud.
