Only water vapor, unless it is winter, and then there would be snow and ice crystals.
Nebulae are clouds of dust and gas that are composed of various chemical elements.
Thin feathery clouds are known as cirrus clouds. These types of clouds are composed of ice crystals and are found at high altitudes in the atmosphere. Cirrus clouds are often wispy in appearance and are associated with fair weather.
Vast interstellar clouds of hydrogen are known as "nebula."
Venus is the terrestrial planet that is permanently covered in clouds. Its thick atmosphere is composed mainly of carbon dioxide with clouds of sulfuric acid, which create a dense layer that obscures the planet's surface from view.
Neptune's clouds are primarily composed of hydrogen, helium, and methane gases. These clouds form distinct bands that circle the planet and contribute to its overall blue appearance. The presence of methane in the atmosphere is responsible for the planet's vibrant blue color.

Clouds are composed of tiny water droplets or ice crystals suspended in the air, making them a mixture of both gas and liquid.

Gaseous water is lighter than air. Clouds are composed (mainly) of gaseous water.
The highest clouds are called cirrus clouds, which form high in the atmosphere. They are wispy and composed of ice crystals.
Cirrus clouds are high-level clouds that are mainly composed of ice crystals. These wispy clouds form at altitudes of 20,000 feet or higher and are often indicators of fair weather. Cirrus clouds are thin and feathery in appearance, giving the sky a streaked or wispy look.

The clouds on Venus are composed of sulfuric acid, which likely originated from sulfur dioxide produced by volcanoes.
Cumulonimbus clouds are high clouds. The contain a large amount of moisture throughout and ice crystals at the top of the clouds. Strong convection currents and heavy winds are found in these clouds. Cumulonimbus clouds produce lightening and hail.
Neptune is surrounded by thick layers of clouds in rapid motion. Winds blow these clouds at speeds up to 700 miles (1,100 kilometers) per hour. The clouds farthest from Neptune's surface consist mainly of frozen methane. Scientists believe that Neptune's darker clouds, which lie below the clouds of methane, are composed of hydrogen sulfide.
High clouds that are composed of ice crystals are classified as "cirrus" clouds. These clouds are typically thin and wispy in appearance, and they form at altitudes above 20,000 feet (6,000 meters). Cirrus clouds often indicate fair weather, but they can also signal that a change in weather may be on the way.
Low-altitude clouds are typically composed of water droplets. They form at altitudes below 6,500 feet and are often associated with fair weather conditions, although they can also bring light precipitation. Examples of low-altitude clouds include cumulus and stratus clouds.
